| Abstract: |
Current and next generations of cosmology surveys (Euclid, LSST, DES, DESI, etc.) will perform an unprecedentedly detailed mapping of the large-scale structure of the universe. In order to access the wealth of cosmological information from these surveys, it is important to develop an accurate theoretical understanding of the underlying physical processes that govern the evolutions of observables like galaxy n-point functions. Some of these key physical processes are the nonlinear clustering of dark matter, the evolution of biased tracers, redshift space distortions, baryonic effects, etc. Recently introduced effective field theory techniques have proven to be a very useful and illuminating tool in the study of these processes. I will discuss this formalism, present some fo the main results and show the comparisons to the n-body simulation results. |
