The distribution of galaxies on the largest scales contains a wealth of cosmological information. I briefly review the current state of our knowledge in light of results from recent large scale cosmological surveys. I will then present some of my own work which utilises the 3-dimensional redshift space distribution of galaxies and allows us to place constraints on key cosmological quantities like the growth rate, the hubble parameter and the angular diameter distance. Combining these dynamical and geometric quantities, with minimal assumptions, allows us to test Einstein's gravity on the large cosmological scales. In the last part of my talk I will discuss some recent work on the 3-point correlation function and modified gravity. |
