In the first part of the talk I will review nonlinear cosmological perturbation theory and show how it can be used to measure cosmological parameters independently of the Planck CMB data. The second part of my talk will be devoted to the probability distribution function of the dark matter density field. I will present a first systematic non-perturbative calculation of this statistic and discuss its potential as a cosmological probe.
Mikhail Ivanov received his PhD at EPFL (Lausanne) joint with IAS Princeton and is currently a Postdoc at NYU.
Mikhail's work involves the interface of cosmology, particle physics, and astrophysics. Recently he was working on analytic approaches to cosmic large-scale structure. Mikhail also developed new methods, inspired by quantum field theory, and use them to analyze observational data in an attempt to learn more about dark matter, dark energy, and the early Universe.
