Description
Determining the connection between the invisible dark matter and the visible distribution of galaxies and gas in the Universe is key not only to understand how galaxy structures form and evolve, but also to use galaxy data to tackle open problems in cosmology like the particle nature of inflation, gravity, dark energy and dark matter. In this talk I will go through a number of recent advances we have made in our ability to make predictions for this visible-dark connection (called "galaxy bias") using state-of-the-art hydrodynamical galaxy formation simulations. I will discuss what these new results have been telling us about the astrophysics of galaxy formation, along with the corresponding consequences to observational tests of various cosmological models.
