Improving cosmological predictions : baryonic effects and analytical techniques in the effective field theory of large scale structure
Abstract/Contents
- Abstract
- The Effective Field Theory of Large Scale Structure (EFTofLSS) is a powerful framework for making accurate predictions of the distribution of matter in the universe on large scales. In this thesis, we have worked in developing the theory in two aspects. First, we studied how to incorporate complex astrophysical processes such as star formation or AGN into the theory, and showed that it is possible to do so, even if not knowing the complete details of the physical processes. We also showed the influence of these baryonic effects on the lensing power spectrum. Second, we used analytical methods borrowed from Quantum Field Theory to calculate the non-linear corrections in the theory. This allowed to do cosmological inference not only using the one-loop power spectrum, but using the one-loop bispectrum as well.
