The first speaker of 2020 is Janet Chen (SU). The seminar will take place Friday 17th of January in room FC61 at 10:30. Title and abstract are included below and in the Albanova agenda. Title: Exploring transients at extreme space phase with ePESSTO+ Abstract: In this seminar, I would like to briefly introduce myself (as I am new here) and the projects I have been working on. I will present the advanced extended Public ESO Spectroscopic Survey of Transient Objects (ePESSTO+) programme. It has gathered the ESO community working on supernovae and unusual transients into one coherent team, developed efficient synergies with multi-messenger experiments and revolutionised the exploitation of wide-field surveys. I was PI of GROND supernova projects, and thus I will focus on the transients followed-up by the ePESSTO and GROND collaboration, which represent the extreme (e.g. the brightest superluminous supernovae or the fastest kilonova) of the luminosity-space of cosmic transients, providing a new dataset to understand their nature. Finally, I will also present the scientific goals of my Marie Skłodowska-Curie fellowship on photometric and spectroscopic sample study of kilonovae with ENGRAVE. https://www.albanova.se/event/astronomy-seminar-janet-chen/ Upcoming events: 24/01 (Fri) @ 10:30: Emil Rivera-Thorsen (SU) 31/01 (Fri) @ 10:30: Jes Jorgensen (NBI) 07/02 (Fri) @ 10:30: John Airy (SU Science Education) 14/02 (Fri) @ 10:30: Per Calissendorff (PhD seminar) Kind regards, Arjan & Cristina ------------------------------------------- Dr. Cristina Barbarino Stockholm University AlbaNova University Center Department of Astronomy SE-106 91 Stockholm - Sweden Tel: +46 (0) 85537 8538 https://www.su.se/english/profiles/cbarb ------------------------------------------- -------------- next part -------------- An HTML attachment was scrubbed...

Our speaker is Emil Rivera-Thorsen (SU): Title: A cosmic Sunburst in stunning GravLens-vision Abstract: Despite a growing consensus that young galaxies contributed the majority of the extreme-UV photons that reionized the early Universe, we still do not have a firm grasp on which mechanisms have allowed these photons to escape through the abundant galactic neutral medium and into intergalactic space. Low neutral column densities can arise either where a hot, luminous stellar population has ionized a large fraction of the galactic gas, or where turbulence, feedback or similar effects have created pathways through the neutral medium along certain lines of sight in an otherwise neutral medium. Realistic systems are generally complicated combinations of these effects; but in their pure form, they define toy models which are very useful to understand the underlying physics. Two years ago, our collaboration took spectra a gravtitationally lensed galaxy at z=2.4, which showed a theoretically predicted, but not previously observed, Lyman-alpha profile arising from light escaping through a narrow, channel with extremely low neutral column density in an otherwise opaque neutral medium, just like its namesake weather phenomenon gives a direct view of the sun through perforated clouds. Follow-up UV imaging with Hubble Space Telescope confirmed that ionizing Lyman-continuum photons in large amounts are pouring out from a very compact region, exactly where this channel was predicted to be, confirming that we are looking straight down the barrel of a narrow perforation of galactic ISM. The galaxy is strongly gravitationally lensed by a massive foreground cluster, which leads to the galaxy being seen in 12 distorted copies, each magnified 10-30 times; adding both extra scientific opportunity and visual spectacle to the mix. https://www.albanova.se/event/astronomy-seminar-emil-rivera-thorsen/ Upcoming events: 31/01 (Fri) @ 10:30: Jes Jorgensen (NBI) 07/02 (Fri) @ 10:30: John Airy (SU Science Education) 14/02 (Fri) @ 10:30: Per Calissendorff (PhD seminar) 21/02 (Fri) @ 10:30: Beibei Liu (Lund) Kind regards, Cristina & Arjan ------------------------------------------- Dr. Arjan Bik Stockholm University AlbaNova University Center Department of Astronomy SE-106 91 Stockholm - Sweden Tel: +46 (0) 85537 8549 https://www.su.se/english/profiles/abik ------------------------------------------- -------------- next part -------------- An HTML attachment was scrubbed...

In fact, most of the molecules detected in the interstellar medium to date have first been found in these regions. These molecules range all the way from simple di- and tri-atomic species to complex organic molecules, some of them with ten atoms or more, that can be considered the starting points for eventual prebiotic chemistry. Recently the Atacama Large Millimeter/submillimeter Array (ALMA) have opened new possibilities for studying this complex chemistry and, in particular, the link between the birth environments of individual stars and the conditions in their protoplanetary disks.

More than 4000 exoplanets have been discovered so far, and most of them are detected by radial velocity and transit methods. These exoplanets can be classified into three populations, hot Jupiters, cold Jupiters and Super-Earths. Studying the formation and evolution of these planets is a popular research topic. Planet formation includes the growth of four characteristic sizes of bodies, dust grain, pebble, planetesimal and planet.

How these bodies grow their masses and what is the major challenging in each stage will also be covered in this talk. > > > https://www.albanova.se/event/astronomy-seminar-beibei-liu/ > > > Upcoming events: > 28/02 (Fri) @ 10:30: Kathryn Kreckel (MPIA and ARI, Heidelberg) > 06/03 (Fri) @ 10:30: Leonardo Tartaglia (SU) > 13/03 (Fri) @ 10:30: Hannah Schunker (MPS, Göttingen) > 20/03 (Fri) @ 10:30: Svetlana Berdyugina (Freiburg) > > Kind Regards, > > Arjan and Cristina > > ------------------------------------------- > Dr. Arjan Bik > Stockholm University > AlbaNova University Center > Department of Astronomy > SE-106 91 Stockholm - Sweden > Tel: +46 (0) 85537 8549 > https://www.su.se/english/profiles/abik > ------------------------------------------- > ------------------------------------------- Dr. Arjan Bik Stockholm University AlbaNova University Center Department of Astronomy SE-106 91 Stockholm - Sweden Tel: +46 (0) 85537 8549 https://www.su.se/english/profiles/abik ------------------------------------------- -------------- next part -------------- An HTML attachment was scrubbed...

Title: Mapping the ionized ISM in nearby galaxies Abstract: The ionized interstellar medium (ISM) provides crucial insights into understanding baryon cycling within disk galaxies and tracing radiative and mechanical feedback from young massive stars. With new VLT/MUSE optical integral field spectroscopy, the PHANGS team now has a wealth of emission line maps that trace different ionization sources and physical conditions across nearby disk galaxies at the 50pc spatial scales needed to isolate individual ionized regions (e.g. HII regions, supernova remnants, planetary nebulae) from surrounding diffuse ionized gas. I will present our most recent results connecting the molecular gas with observed sites of massive star formation, and measuring the gas phase oxygen abundances across thousands of HII regions. Within the context of the large scale galactic environment, these studies have implications for our understanding of how spiral structure acts to organize and mix the ISM, and regulate star formation. https://www.albanova.se/event/astronomy-seminar-kathryn-kreckel/ Upcoming events: 28/02 (Fri) @ 10:30: Kathryn Kreckel (MPIA and ARI, Heidelberg) 06/03 (Fri) @ 10:30: Leonardo Tartaglia (SU) 13/03 (Fri) @ 10:30: Hannah Schunker (MPS, Göttingen) 20/03 (Fri) @ 10:30: Svetlana Berdyugina (Freiburg) 27/03 (Fri) @ 10:30: TBD Kind Regards, Arjan and Cristina ------------------------------------------- Dr. Arjan Bik Stockholm University AlbaNova University Center Department of Astronomy SE-106 91 Stockholm - Sweden Tel: +46 (0) 85537 8549 https://www.su.se/english/profiles/abik ------------------------------------------- -------------- next part -------------- An HTML attachment was scrubbed...

Our speaker is Michael Maseda from the University of Leiden (The Netherlands) Title: Spectroscopy of Galaxies in the Early Universe: A JWST Sneak Peek Abstract: Even though the first population of star-forming galaxies at z > 6 have been discovered in the deepest imaging campaigns with the Hubble Space Telescope, the redshift and intrinsic faintness of these objects currently present a challenge for spectroscopy. As such, relatively little is known about the physical conditions in galaxies at the earliest cosmic times and the limited observations we do have pose challenges to current stellar population models. We can, however, make progress on these issues with spectroscopic observations of “extreme” galaxies at lower redshifts (1 < z < 6). I will highlight my recent work in this direction from cutting edge facilities such as MUSE on the VLT as well as ultra-deep HST imaging and spectroscopy. In one particular region, the Hubble Ultra Deep Field, I have used these two facilities to construct a census of star-forming galaxies to unprecedented depths. This includes an abundant population of galaxies with physical properties similar to those at the highest redshifts, and a hitherto invisible population that represent the faintest and lowest-mass galaxies ever discovered at cosmological distances. Detailed studies of these populations serve as a preview of science in the JWST era, shedding light onto the galaxy formation process and cosmic Reionization. We will have the colloquium using zoom.

Our speaker is Leonardo Tartaglia from the Astronomi Department (SU) Title: Interacting supernovae and their progenitors from long-term monitoring Abstract: While modern surveys are able to discover and classify new optical transients within one day or less from their explosions, the proper characterization of their progenitor stars is still a partially unsolved astrophysical issue. The most common interacting supernovae are believed to arise from the core-collapse of massive stars ejecting fractions of their envelopes during the last stages of their lives. Direct evidences of luminous blue variables as progenitors of these transients is enclosed in deep archival images, while several indirect evidences point to less massive stars as candidate progenitors of at least a fraction of these transients. Indirect methods can help us to determine physical properties of progenitors and their surroundings, and require high-quality data, and good multi-wavelength monitoring of interacting transients up to very late times after explosion. During this colloquium, we will see how long-term photometric and spectroscopic follow-up campaigns, combined with early discoveries and multi-wavelength observations, can help us in characterizing this relatively rare and still poorly understood class of optical transients. https://www.albanova.se/event/astronomy-seminar-interacting-supernovae-and-their-progenitors-from-long-term-monitoring/ We will have the colloquium using zoom.

Our speaker is Daohai Li from Lund University. Title: Flyby encounters between two planetary systems Abstract: Stars formed in clustered environment may experience stellar encounters. Here we explore a case where both encountering stars each has its own planetary system of various orbital scales and mass ranges. Besides the immediate effect of the encounter, we have also propagated the systems post-encounter for up to Gyr. So we reveal the effect of a captured planet on a system that survives the encounter itself. We find that immediately during the encounter, a planet can be ejected from its original host star or captured by the intruding star. Here, the interplanetary interactions are negligible and a planet’s stellar-centric distance is a key factor in constraining its stability. Then, during the long-term post-encounter evolution, the interplanetary forcing takes control. The larger the perturbation a system acquires immediately during the encounter, the more likely and the earlier it becomes unstable in the later phase. Captured planets intensify the post-encounter instability and they themselves are often lost.

Our speaker is Clare Dobbs from the University of Exeter (UK). Title: Star formation in spiral arms Abstract: Numerical simulations of galaxies are an important tool for studying the evolution of the interstellar medium (ISM), and I will start by reviewing some fo the results on star formation and giant molecular clouds (GMCs) which have resulted from these types of simulations. I will also highlight some recent results, which model the nearby galaxy M33, and are able to provide a good match to both the overall structure of M33, and the properties of GMCs observed in CO surveys of M33. However whole galaxy simulations typically lack the resolution to effectively follow cluster evolution, and accurately model processes such as stellar feedback. I will show some current work in our group, which aims to model these processes in more detail. We show simulations which fully model ionisation from massive stars as well as including spiral arms in a galaxy subsection. We find ionisation has a surprisingly large scale effect on the ISM, effecting the densities of filaments and structures along the spiral arms, and triggering new star formation. Such results have not been shown before since previous simulations were typically limited to individual, isolated molecular clouds. We also show more localised simulations which focus on the formation of young massive clusters (YMCs). We propose that the formation of clusters by colliding flows can enable the rapid build up of large amounts of gas over short timescales, matching the observed characteristics of YMCs. We compare some of our simulated clusters to the masses and radii of Milky Way clusters. Finally we highlight future work aiming to fully resolve and model stellar clusters on spiral arm scale simulations, investigating the effects of spiral arm strength, gas velocity fields and stellar feedback. https://www.albanova.se/event/astronomy-seminar-clare-dobbs/ We will have the colloquium using zoom. You will find the invitation at the end of this email. Some guidelines: 1) Join the session with your microphone muted. 2) When you have a question, press the “raise hand button” and wait till you are asked to ask your question. 3) The session will be online from 10:20, please join at least a few minutes early as we would like to start 10:30 sharp. We hope to see all of you there!

Our speaker is Sven Wedemeyer from the University of Oslo (Norway). Title: Observing the Sun with ALMA – Challenges, scientific potential, and first results Abstract: The Atacama Large Millimeter/sub-millimeter Array (ALMA) in Chile is an interferometric array that consists of 66 antennas. Regular observations of the Sun with ALMA, which started in 2016, provide a new diagnostic tool for studying the solar chromosphere. The requirements for solar observations are different from many other observations with ALMA in the sense that the mapped atmospheric layers of the Sun evolve on very short timescales and the primary beam being filled with complex emission. High-cadence (snapshot) imaging is needed for such a dynamic target but it is very challenging. While the development of the solar observing mode is ongoing, ALMA now provides first scientific data featuring, among other things, the imprint of magnetic fields and propagating shock waves. I will give a brief introduction to ALMA and its diagnostic potential for the Sun. The challenges with carrying out solar observations and post-processing the data will be addressed and first examples for Band 3 and Band 6 data and first scientific results will be presented. https://www.albanova.se/event/astronomy-seminar-sven-wedemeyer/ We will have the colloquium using zoom. You will find the invitation at the end of this email. Some guidelines: 1) Join the session with your microphone muted. 2) When you have a question, press the “raise hand button” and wait till you are asked to ask your question. 3) The session will be online from 10:20, please join at least a few minutes early as we would like to start 10:30 sharp. We hope to see all of you there! After the summer break we will start again on the 28th of august with the fall seminar series, most likely also via zoom. We wish you all a great summer!

Next week we will start again with the Astronomy seminars. We will continue the seminars via zoom. On Monday August 24, 10:30 we will have the PhD seminar of Veronica Menacho: Title: Impact of feedback on the ISM of extreme starburst galaxies Abstract: Blue compact galaxies (BCGs) are metal-poor, starbursting galaxies with characteristics similar to the young high-redshifted galaxies. Their starburst condition favoured the formation of thousands of massive stars that are continuously injecting energy, heat and momentum into the ISM. These feedback mechanisms strongly affect the condition of the surrounding gas or even the gas of the entire galaxy. In this talk I will present results from my work during my PhD studies. We have used the nearby starburst and Lyman continuum emitting galaxy Haro 11 as a benchmark to study in detail a) the impact of stellar feedback on the ISM of strong starbursting galaxies; b) the mechanisms that favour the escape of LyC photons out of the galaxy; and c) the condition of the gas under extreme environments. We used deep VLT/MUSE data, that allowed us to get a 3D view of the internal structure of the galaxy.

Our speaker is Lorenz Roth from KTH and he will speak about: Title: The ongoing search for water plume activity on Jupiter’s moon Europa Abstract: Jupiter’s moon Europa might harbor life in its vast water ocean below the thick ice crust. This deep subsurface habitat could potentially be investigated at locations of active outgassing, giving the question whether Europa is geologically active a crucial importance. Evidence for present-day activity yet remained elusive for decades. In 2012, Hubble Space Telescope observations revealed localized hydrogen and oxygen emissions, refueling the idea that Europa is actively outgassing water vapor. Following this detection several studies derived the existence of water vapor plumes on various locations. These studies used a variety of methods from remote-sensing telescope observations (HST, Keck) to in-situ spacecraft magnetic field and plasma measurements. However, the final proof for the existence of active water plumes is still missing. I will review the different studies claiming evidence and explain why we still do not understand Europa’s plume activity. https://www.albanova.se/event/astronomy-seminar-via-zoom-lorenz-roth/ We will have the colloquium using zoom. You will find the invitation at the end of this email. Some guidelines: 1) Join the session with your microphone muted. 2) When you have a question, press the “raise hand button” and wait till you are asked to ask your question. 3) The session will be online from 10:20, please join at least a few minutes early as we would like to start 10:30 sharp. We agreed with the organisers of the astronomy seminars in Uppsala to share this invitation also with the astronomy institute in Uppsala. We hope to see all of you there!

Our speaker is Chris Usher from Stockholm University and he will speak about: Title: Studying Galaxy Formation with Globular Cluster Stellar Populations Abstract: Globular clusters are powerful probes of galaxy formation and assembly. The properties of globular clusters observed today reflect both the conditions of globular cluster formation but also the physics of globular cluster survival. Recent theoretical work has shown a strong connection between a galaxy's formation and assembly history and the distribution of the galaxy's globular clusters in age-metallicity space. Due to the age-metallicity degeneracy in the optical, reliably measuring extragalactic globular cluster ages has been observational challenging. I will present a novel method that combines optical photometry and near-infrared spectroscopy to provide ages for large samples of globular clusters. I will present results from applying this technique to data from the SLUGGS survey and to GCs around M31. I will also look to the future and discuss how forthcoming wide field surveys such as LSST will provide a volume limited sample of globular cluster systems. https://www.albanova.se/event/astronomy-seminar-via-zoom-chris-usher/ We will have the colloquium using zoom.

The properties of globular clusters observed today reflect both the conditions of globular cluster formation but also the physics of globular cluster survival. Recent theoretical work has shown a strong connection between a galaxy's formation and assembly history and the distribution of the galaxy's globular clusters in age-metallicity space. Due to the age-metallicity degeneracy in the optical, reliably measuring extragalactic globular cluster ages has been observational challenging. I will present a novel method that combines optical photometry and near-infrared spectroscopy to provide ages for large samples of globular clusters. I will present results from applying this technique to data from the SLUGGS survey and to GCs around M31. I will also look to the future and discuss how forthcoming wide field surveys such as LSST will provide a volume limited sample of globular cluster systems. > > https://www.albanova.se/event/astronomy-seminar-via-zoom-chris-usher/ > > We will have the colloquium using zoom.

Our speaker is João da Silva Santos from Stockholm University and he will speak about: Title: Probing the solar chromosphere with millimeter interferometry Abstract: The landscape of active regions in the solar atmosphere is marked by extended, bright patches named plage regions as well as loop-like structures which trace magnetic field lines that confine plasma several megameters above the solar surface. Within these environments, it is also common to observe different types of small-scale, short-lived optical and ultraviolet brightenings, which have been linked to magnetic reconnection processes in the low atmosphere. Therefore, solar active regions can be regarded as plasma laboratories for the study of the interplay between gas dynamics and magnetic fields. However, progress has been somewhat hampered partly due to the difficulty in interpreting the most widely used spectral diagnostics. In this seminar I will discuss how a new observing window opened by the Atacama Large Millimeter/submillimeter Array (ALMA) can be used to address many unsettled questions in solar physics and, particularly, I will show some of the first results of solar active region studies with ALMA. The diagnostic capabilities of the millimeter continuum for both hot and cold regions and for persistent heating in plage and transient phenomena in flux emergence regions will be highlighted. I will also explore the synergy between ALMA and other facilities observing at different wavelengths. We will have the colloquium using zoom. You will find the invitation at the end of this email. Some guidelines: 1) Join the session with your microphone muted. 2) When you have a question, press the “raise hand button” and wait till you are asked to ask your question. 3) The session will be online from 10:20, please join at least a few minutes early as we would like to start 10:30 sharp.

Our speaker is Freeke van der Voort from Cardiff University, UK. Title: Cosmic gas flows in the circumgalactic medium around Milky Way-like galaxies Abstract: Galaxies are intimately connected to the environments they live in. The haloes around them contain the gas reservoir from which the galaxies grow, while galactic outflows heat and enrich this ‘circumgalactic medium’ (CGM). Using cosmological, magnetohydrodynamical simulation we will discuss the physical and observable properties of the gas around galaxies. The simulations use a new simulation refinement technique to reach orders of magnitude higher resolution than the current state-of-the-art. These spatially refined simulations show that the CGM has more ‘cool’ gas than previously thought, which strongly affects predicted observables in the CGM: The neutral hydrogen (HI) column densities are dramatically enhanced, more in line with observations. I will also show how the presence of magnetic fields alters the gas flows into and out of galaxies, resulting in less mixing and higher gas fractions inside the halo. I will briefly discuss the effects on the galaxies themselves. https://www.albanova.se/event/astronomy-seminar-via-zoom-freeke-van-der-voort/ We will have the colloquium using zoom.

I will briefly discuss the effects on the galaxies themselves. > > > > We will have the colloquium using zoom.

Our speaker is Ernest Alsina from Locarno, Switzerland. Title: Magnetic sensitivity of the H I Lyman-α scattering polarization wings in the solar disk radiation. Abstract: The linear polarization signals arising from scattering processes in the H I Lyman-α line in the solar disk radiation represent a valuable observable for probing the chromosphere-corona transition region (TR) and the underlying chromospheric plasma. Whereas the line-center signal encodes information on the magnetic activity and geometry of the TR, the broad large-amplitude scattering polarization signals in the wings, produced through the joint action of partial frequency redistribution and J-state interference, had generally thought to be insensitive to the influence of magnetic fields. However, our investigations show that such Q/I and U/I wing signals are in fact sensitive to the presence of chromospheric magnetic fields with a significant longitudinal component. This sensitivity arises from the magneto-optical (MO) effects that introduce a coupling between the transfer equations for Stokes Q and U and it becomes appreciable for field strengths similar to those for which the Hanle effect operates in the line core (approximately between 5 and 100 gauss), being well below those required for sizable signals to be produced through the familiar Zeeman effect. In this talk, we begin by giving a primer on the main physical mechanisms that give rise to polarization phenomena in this line. We then show the results of a series of numerical radiative transfer calculations, highlighting the sensitivity to MO effects both in its wing and frequency-integrated linear polarization signals. The theoretical results presented here further enhance the diagnostic interest of the unprecedented spectropolarimetric and broadband observations obtained by the Chromospheric Lyman-Alpha Spectropolarimeter (CLASP) sounding rocket mission. https://www.albanova.se/event/astronomy-seminar-via-zoom-ernest-alsina/ We will have the colloquium using zoom.

Our speaker is Enric Palle from the IAC in Spain. Title: Observing planetary atmosphere at high spectral resolution. The path from Hot Jupiters to biomarkers. Abstract: With over 4000 confirmed planets, one of the main goals of exoplanets research is the detailed characterization of the most accessible planetary systems, including the bulk atmospheric composition of their atmospheres. Space and ground-based planet searches are concentrating on finding the brighter and closer stars to us hosting exoplanets. Most of the atmospheric characterization so far has been carried out using space facilities such as HST, Spitzer and soon JWST and Ariel. However, ground-based instrumentation, particularly using high-dispersion spectrographs, is quickly becoming a powerful tool to perform transmission spectroscopy and cross-correlation studies in search for molecular, atomic or ionized species signatures in planetary atmospheres. Here I will review the major achievements in planetary atmospheric characterization using these techniques, including the latest highlights from instruments such as CARMENES and ESPRESSO. Finally I will discuss the potential discovery space for this type of techniques (including biomarker detection) when similar instrumentation is available at the Extremely Large Telescope facilities currently under construction. https://www.albanova.se/event/astronomy-seminar-via-zoom-enric-palle/ We will have the colloquium using zoom.

Abstract: The brightest and longest-lasting supernovae radiate about about a hundred times more energy than typical events. These “superluminous” supernovae were discovered only about 15 years ago, and their stellar progenitors and the mechanisms by which they radiate so much energy are under much debate. SN 2006gy was one of the first observed such supernovae, and still one of the brightest ever seen. It showed signs of circumstellar interaction with a massive hydrogen-rich envelope that must have been ejected shortly before the supernova. In 2008 spectroscopy of the ejecta revealed emission lines that had not been seen before in any supernova and could not be identified. I present a resolution to this long-standing mystery, showing that the lines can be convincingly identified with neutral iron. Further, the properties of the lines point towards a large mass of iron in the ejecta, at least a third of a solar mass. I discuss how this new discovery means problems for most models proposed so far for SN 2006gy - all involving the explosion of a very massive star - and outline a path toward a new scenario instead involving a white dwarf spiralling into the envelope of a red giant or supergiant companion. https://www.albanova.se/event/discovery-of-a-massive-iron-reservoir-in-superluminous-supernova-sn-2006gy/ We will have the colloquium using zoom.

I discuss how this new discovery means problems for most models proposed so far for SN 2006gy - all involving the explosion of a very massive star - and outline a path toward a new scenario instead involving a white dwarf spiralling into the envelope of a red giant or supergiant companion. > > https://www.albanova.se/event/discovery-of-a-massive-iron-reservoir-in-superluminous-supernova-sn-2006gy/ > > We will have the colloquium using zoom.

Our speaker is Jérôme Guilet from the CEA Saclay, Paris. Title: Magnetar formation & extreme explosions. Abstract: Extremely strong magnetic fields of the order of 10^15 Gauss are required to explain the properties of magnetars, the most magnetic neutron stars. Such a strong magnetic field is expected to play an important role for the dynamics of core-collapse supernovae, and in the presence of rapid rotation may power superluminous supernovae and hypernovae associated to long gamma-ray bursts. The origin of these strong magnetic fields is still uncertain and most likely requires an amplification over several orders of magnitude in the protoneutron star. I will review our current understanding of the physical processes that can lead to this magnetic field amplification, including the magnetorotational instability and the convective dynamo. I will also describe how the explosion dynamics depends on the properties of the magnetic field. https://www.albanova.se/event/jerome_guilet/ We will have the colloquium using zoom.

Eldridge In-Reply-To: References: Message-ID: Dear all, In the SU Astronomy seminars, we would like to extend the topics to not only science but also to diversity and social topics, in the context of the academia community. This Friday we invited Jan J. Eldridge to give a seminar talk about binary exploding stars and additionally about "gender binary". It was highlighted by the Section Dean of SU that all departments must try to increase the number of seminars by underrepresented gender. The LGBTQ group is definitely underrepresented and it's a great opportunity that JJ is willing to share her/their view with us. Moreover, during discussions on the day of "strike" to support the black life matters movement, the OKC working environment group keeps addressing the issue of anti-black racism in academia. In a seminar next year, we will have the other talk about racism in academia. On Friday November 27 at 10:30 we will have the next Astronomy Seminar, remotely via zoom. Our speaker is Jan J. Eldridge (please note her/their pronouns are she/her/them/they and please call her/them Jan or JJ) from the University of Auckland. Title: Exploding binaries: stars and gender. Abstract: Most of the stars in the Universe are not single like our Sun but in binary stars systems. A binary star is composed of two stars in orbit around each other, as they age they can "get-in-each-others" way and experience very different evolution to that our stars like our Sun. Only over the last decade it has become clear that to accurately understand the Universe we need to take account of these interacting binary stars. In my talk I will go over a few examples showing how understanding binary stars allows us to understand the appearance of galaxies, the diversity of supernovae and the production of gravitational wave transients.​ There is also another binary that has been exploded recently, that is the assumption that gender is a binary. After discussing astrophysics I'll discuss gender diversity and how to make academia more welcoming for trans and gender diverse people with a few examples from science fiction. https://www.albanova.se/event/jj_eldridge/ We will have the colloquium using zoom.

After discussing astrophysics I'll discuss gender diversity and how to make academia more welcoming for trans and gender diverse people with a few examples from science fiction. > > https://www.albanova.se/event/jj_eldridge/ > > > We will have the colloquium using zoom.

Our speaker is Jorryt Matthee from ETH, Zürich, Switzerland. Title: (Re)solving the formation of galaxies in the 2020s Abstract: Over the recent decades, observational and theoretical developments have lead to a consensus picture of the formation of galaxies in a LCDM framework. With new large surveys and space missions on the horizon, we are now suited to explore new, bold and more detailed questions in the 2020s: When did the first stars form and what were their properties? Which sources of light were the main drivers of cosmic reionisation? What drives the variation in galaxy' star formation histories and their chemical evolution, and how is this connected to the dark matter assembly? These questions are particularly challenging as they describe complex, multi-scale and multi-dimensional phenomena. Observations furthermore are fundamentally limited by resolution and sensitivity and can not be used for longitudinal studies. In this framework, I will first discuss results from cosmological hydrodynamical simulations. I will present explorations of the multi-dimensional relations between the assembly of dark matter halos, star formation histories and stellar alpha-enhancement that can be tested with large upcoming galaxy surveys. I will then move to the mostly uncharted territory of the observational study of the most distant galaxies and present results from recent attempts to witness the assembly of galaxies in the first few Gyr of cosmic time. I will emphasise the role of the bright Lyman-alpha line in observations of faint distant galaxies to study the process of reionisation, and to help identifying galaxies with very young stellar populations. I will briefly discuss what we can expect to learn from future observations with JWST and the ELT. https://www.albanova.se/event/resolving-the-formation-of-galaxies-in-the-2020s/ We will have the colloquium using zoom. You will find the invitation at the end of this email. Some guidelines: 1) Join the session with your microphone muted. 2) When you have a question, press the “raise hand button” and wait till you are asked to ask your question. 3) The session will be online from 10:20, please join at least a few minutes early as we would like to start 10:30 sharp. We hope to see all of you there! Arjan & Janet ========================================= Arjan Bik is inviting you to a scheduled Zoom meeting.
