Title: See description
Description: Christian Fidler: From Newton to Einstein: Large-Scale Signatures of GR in Galaxy Surveys. Abstract: Newtonian N-body simulations can be consistently embedded in general relativity. I discuss the basic framework of Newtonian motion gauges, the application of a GR dictionary in practice and which effects are missed by an ordinary Newtonian analysis. Julien Lesgourgues : Could the Hubble tension hint at new particle physics Abstract: the fact that cosmological data sets (like measurements of H0 or sigma8) are in tension with others is a model-dependent statement. It is however very difficult to reconcile these datasets with simple extensions of the minimal LambdaCDM model. Instead I will argue that new particle physics (with a dark sector and dark forces) could do the job. I will present the results of very recent fits to the data supporting this claim.
