The next big test for cosmology: the non-linear scales of structure formation

17.09.2021 11:30 – 12:30

One exciting opportunity to push our understanding of the Universe is the under-utilised small (non-linear) scales of cosmic structure formation. Upcoming galaxy survey missions promise tiny measurement errors at these scales where even the tiniest deviation to the standard model, ΛCDM, would provide strong evidence for non-standard physics. This hinges on our ability to accurately model the galaxy distribution in a theoretically agnostic way. I describe a promising framework to model the matter correlations in the non-linear regime of structure formation at the required accuracy while accounting for possible deviations to ΛCDM, massive neutrinos, and baryonic physics.
