Bagla Affiliation: IISER, Mohali Conference ID: ASI2016_635 Title : Gravitational clustering in an expanding universe Abstract Type : plenary Abstract : I will describe the equations of motion for non-relativistic matter in an expanding universe and discuss generic aspects of dynamics and clustering. With the use of quasilinear approximations and spherical collapse, we can understand the key features of large scale structure. I will discuss the impact of dark energy on dynamics and growth of perturbations. It may be possible to probe characteristics of dark energy by studying dynamics in the vicinity of clusters of galaxies. |
