Welcome to the home page of the Galaxies and Cosmology Theory group led by Annalisa Pillepich.


Was wir im Team machen (auf Deutsch): https://www.youtube.com/watch?v=bpwJqTppNjQ

We focus on modeling and understanding the formation and evolution of cosmic structures and galaxies in the context of the standard cosmological model and its plausible alternatives.


Our goals

  1. to provide a self-consistent theoretical framework for the interpretation of observations pertaining the Local Universe, as well as galaxies at higher redshifts and in diverse environments
  2. to advance the modeling of baryonic processes in galaxy formation, and therefore to quantify their effects onto the underlying DM structures
  3. to ultimately enhance the reliability of galaxies and galaxy clusters as tools to refine and test the fundamentals of the ΛCDM model
