Limitations of Standard Perturbation Theory and EFT Corrections in Large Scale Structure

Explore a comprehensive lecture on advanced cosmological concepts delivered by Henrique Rubira from LMU/Cambridge at ICTP-SAIFR, covering fundamental limitations of standard perturbation theory and the necessity of Effective Field Theory (EFT) corrections in cosmological studies. Delve into crucial topics including renormalization in Cosmological EFT, distinctions between Eulerian and Lagrangian perturbation theory, galaxy bias expansion, and Redshift-Space Distortions (RSD). Learn about parameter estimation techniques and their application in comparing theoretical models with observational data. Master these advanced concepts through this in-depth two-hour presentation, part of the Minicourse on Effective Field Theory in Large Scale Structure held at IFT/UNESP in São Paulo, Brazil.
