VIRTUAL INPA SEMINAR | Joseph DeRose (UC Santa Cruz)
January 29, 2021 @ 12:00 pm - 1:00 pm
Speaker: VIRTUAL INPA SEMINAR | Joseph DeRose (UC Santa Cruz)
Title: “Models of the Non-Linear Universe for Precision Cosmology”
Abstract:
Imaging and redshift surveys of galaxies and high resolution observations of the CMB promise to shed light on the physical nature of dark matter and dark energy in the coming decade. One of the main factors limiting the precision and accuracy of cosmological constraints coming from these measurements will be our understanding of how non-linear structure forms in our universe. In this talk I will present a roadmap for leveraging cosmological simulations to improve this understanding. First, I will discuss recent progress on combining perturbative models of structure formation with N-body simulations in order to obtain highly optimized predictions for real-space galaxy clustering and weak lensing, and describe how similar models might be used to confront a variety of observations. I will then show how realistic models of galaxy formation and evolution combined with contemporary machine learning techniques can be used as robustness tests for complex cosmological analyses, with case studies from the Dark Energy Survey and the Dark Energy Spectroscopic Instrument.
