Cosmology/galaxies discussion group

The idea is to discuss interesting current topics that are of interest for cosmology and galaxy/clusters astrophysics and bring together different groups at USM to discuss common strains of research; examples of subjects that I would find interesting to discuss are e.g.:
  • What can we learn with current and upcoming cosmological surveys (SDSS-IV, DES, DESI, Euclid, LSST… , but also CMB data) about open questions in astrophysics if we assume cosmology to be known - e.g. HOD modelling and connection to galaxy evolution, AGN and SN feedback, etc.
  • What degeneracies are there that need further study between astrophysics and cosmology - e.g. between baryonic effects and neutrino mass on the small-scale clustering.
  • Any aspect of observational cosmology (especially related to galaxy surveys and CMB observations).
  • Any other topic that you find interesting.
