Title: Some analytical approaches for cosmological large-scale structures
Time: 10:30-12:00
Location: Seminar room @ 1st floor of Sci.Bldg. No.4

We present a few analytical methods that can be used to describe the statistical properties of cosmological large-scale structures, such as the matter power spectrum and bispectrum, the halo mass function, and the probability distribution of the matter density. In particular, we discuss some perturbation methods as well as toy models that can provide some insight in the dynamics.
Finally, we explain how such methods can be applied to other models than the standard LCDM cosmology, such as modified-gravity or WDM scenarios.
