Giovanni Camelio (post-doc at the SU astronomy department) will give a talk titled: Early evolution of newly born proto-neutron stars. Here the abstract: %%%%%%%%%%% We evolve a proto-neutron star (PNS) with a nuclear many-body theory equation of state (EoS), for the first tens of seconds after the core bounce. In particular, we have determined the neutrino signal on terrestrial detectors and the frequencies of the gravitational waves due to stellar oscillations. Including rotation in an effective way, we also determine the time variation of the rotation rate and the neutrino angular momentum loss of the PNS with the GM3 mean-field EoS, and determine the corresponding gravitational wave signal due to rotation as the PNS contracts. We find that the mass shedding limit restricts the initial angular momentum and consequently the final rotation rate must be smaller than about 300 Hz for a PNS of about 1.6 solar masses. These results are obtained using a new code we have developed which describes the PNS evolution in spherical symmetry. This code integrates the neutrino number and energy transport equations together with the relativistic stellar structure equations by iteration. The neutrino cross sections are determined consistently with the underlying EoS. To include the many-body EoS in the evolution, we have find and tested a new fitting formula for the interacting part of the baryon free-energy, valid at finite temperature. %%%%%%%%%%% Regards /Francesco ------------------------------------------- Francesco Taddia Postdoctoral Researcher Department of Astronomy Stockholm University, Sweden ftadd at astro.su.se -------------- next part -------------- An HTML attachment was scrubbed...

Here the abstract: NGC6217 is a nearby (z=0.005) spiral galaxy. A variety of multi band data highlights various aspects of its central core resulting in multiple types of classifications, from a pure starburst to a Seyfert nucleus. Pietsch+2001 reported a jet emanating from the nucleus of NGC6217 in the Rosat X-ray images. The structure is composed by three knots and it is extended over 19 kpc. We have studied four observations from XMM Newton satellite, studying the images and the spectra of the central core and the knots in order to understand their nature. The spectra of the central core are well represented by a complex starburst-AGN core. The XMM images confirm the presence of the jet structure. The spectra of the knots are harder than the spectrum of the core, in agreement with the jet hypothesis. Additional HST and VLA data display a complex nucleus with several condensations, suggesting a low luminosity AGN core coexisting with a starburst region. The accretion rate estimated in our study is consistent with an ADAF accretion mode. cheers /Francesco ------------------------------------------- Francesco Taddia Postdoctoral Researcher Department of Astronomy Stockholm University, Sweden ftadd at astro.su.se -------------- next part -------------- An HTML attachment was scrubbed...

The basic detection principle and simulations that address selected particle and astrophysical aspects will be discussed. As the signal is observed on top of a large dark rate background, IceCube cannot resolve individual neutrino interactions at these low energies to determine energy, direction and the neutrino type. Investigations that help to remedy this situation and joint measurements of various neutrino and gravitational wave experiments will be mentioned. cheers /Francesco ------------------------------------------- Francesco Taddia Postdoctoral Researcher Department of Astronomy Stockholm University, Sweden ftadd at astro.su.se -------------- next part -------------- An HTML attachment was scrubbed...

Aug 23 @ 13:30 To: "people at nordita.org" , "alla at astro.su.se" < alla at astro.su.se> Dear All, The next Nordita Astrophysics Seminar will be tomorrow *Wednesday Aug 23 at 13:30* (room 122:026*, Nordita West Building*). Speaker: Andrei M. Beloborodov (Columbia Univ.) Title: *Physics of magnetars* Abstract: Magnetars are neutron stars born with ultra-strong magnetic fields. Their spectacular X-ray activity is fed by dissipation of magnetic energy. The dissipation mechanism will be discussed, including processes inside and around the star. Welcome!

The workshop aims to discuss the state-of-the-art approaches, challenges for the next-generation hybrid MHD-PiC and radiation-PiC methods and outline the problems to be answered by the new exascale simulations of Nature in silico. It will bring together experts in high-performance computing, numerical methods, plasma physics and radiative processes. The program of the workshop is available at http://www.nordita.org/exa2017 You are welcome to listen to the talks.

Abstract: PoGO+ is a purpose-built and calibrated balloon borne polarimeter flown from the north of Sweden in the summer of 2016. The polarization of emissions from the Crab, as measured during the flight in 2016 is reported for the energy range (~20-160 keV). The Crab is a complex system consisting of a central pulsar, a diffuse pulsar wind nebula, as well as structures in the inner nebula including a jet and torus. Source and background observations are interspersed allowing for a rigorous background subtraction eliminating systematic effects. The polarization vector is found to be aligned with the spin axis of the pulsar for a polarization fraction, PF = (20.9 ± 5.0)%. Contrary to measurements at higher energies, no significant temporal evolution of phase-integrated polarisation parameters is observed. Through phase selections the off-pulse (OP) and pulsar (P1, P2) can be studied separately. The polarization properties of nebula dominated OP are compatible with the phase-integrated results. The polarization parameters for the pulsar itself (P2) are measured and are consistent with observations at optical wavelengths. Additionally, the instrument design and analysis methodology is detailed. cheers /Francesco ------------------------------------------- Francesco Taddia Postdoctoral Researcher Department of Astronomy Stockholm University, Sweden ftadd at astro.su.se > On 31 Aug 2017, at 13:26, Francesco Taddia wrote: > > Dear all, > > it is time to restart our extreme object meetings after the summer break. > > Mark these first three dates on your calendar: > > 1) Next Thursday, 7/9, Federica Bianco (Center for Urban Science and Progress > and NYU Center for Cosmology and Particle Physics) will talk about LSST and > the recent adventures of an astrophysicist in urban science. > > 2) On 28/9, we will have a talk titled "Shedding new light on the Crab with polarized X-rays" by the PoGo+ collaboration. > > 3) On 12/10 we want to have another EO meeting, and > we kindly ask for volunteers to give a talk! > > The meetings will be at 13:00-14:00, @ KTH meeting room on the 5th floor. > > cheers > > /Francesco > ------------------------------------------- > Francesco Taddia > Postdoctoral Researcher > Department of Astronomy > Stockholm University, Sweden > ftadd at astro.su.se > > > > > > > > > > > ------------------------------------------------- > okc-wp4 at albanova.se mailing list -------------- next part -------------- An HTML attachment was scrubbed...
