DEX-XIX: 19th Durham-Edinburgh eXtragalactic Workshop

10 Jan 2023, 10:30 → 11 Jan 2023, 18:00 Europe/London

Progress in the new era of cosmology and galaxy evolution

The next generation of instruments and surveys is beginning to provide us with new data, producing our best ever measurements of galaxies at very high redshifts. This new data is questioning our current models of galaxy formation and evolution (e.g. with JWST), and our models of cosmology and gravity (e.g. DESI and Euclid). At the same time, many advances are being made in hydrodynamical simulations (e.g. MillenniumTNG) and theoretical models, which are necessary to take full advantage of this new data. Conjointly, our theories and observations are improving our understanding of the early Universe and its evolution to the present day, from the galaxies in the local group to the large-scale structure of the Universe.

This meeting aims to bring together observers and theorists to discuss progress in modelling, simulations and observations at the frontier. Along the way, we hope to create a space where we can freely exchange new ideas and foster collaborations among our respective research groups.
