[Astronomy seminar] Astronomy seminar via zoom, 11 December 10:30: Jorryt Matthee

[Astronomy seminar announcements]

Dear all,

On Friday December 11 at 10:30 we will have our last Astronomy Seminar of 2020, remotely via 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.
