Testing gravity at cosmological scales: from linear to nonlinear regimes
Speaker(s): Pengjie Zhang
Abstract: Observations are opening new windows to test general relativity at cosmological scales. In this talk, I will discuss how gravity determines the expansion and structure formation of the universe, what smoking guns of gravity in the cosmos we are expecting, what difficulties we are facing to perform unambiguous tests of gravity and what are possible ways to overcome these difficulties.
