Evolving Galaxies in Evolving Environments

The programme of the conference will cover the following topics:

  • Evolving environments: clusters, groups, density field, clustering, dark matter environment, and how they depend globally on redshift)
  • Central galaxies: links between accretion, bulge growth, star formation & AGN feedback, including BCGs.
  • Multiphase gas and environment: observations and simulations of gas budget vs halo mass, hot gas (detection, cooling, stripping), warm gas (absorption studies, abundance), cold gas (detection of flows, abundance).
  • Satellite galaxies: direct evidence of interaction with environment, physical mechanisms, simulations, empirical trends.
  • Tight interactions and no interactions: merging, close pairs, compact groups, fossils/isolated galaxies, etc.

The Emergence of Disk Galaxies

Recent multi-wavelength observations suggest that the first sizable disk galaxies emerged at redshifts 2-3, when the Universe was most actively forming stars.  These disk galaxies look remarkably different than their local counterparts, being more turbulent, clumpier, and forming stars several orders of magnitude faster.  This focused, mid-sized workshop will bring together multi-wavelength observers and theorists interested in understanding what drives the observable properties of disk galaxies across cosmic time, how they transform from their progenitors at high redshifts into their descendants today, and what they tell us about star formation and feedback processes during Cosmic Noon.
