In this talk I will describe some of my recent work on using large-scale velocity probes to contrain cosmology. I will explain how models with primordial non-Gaussianity leave signatures on the velocity PDF of both dark matter field and biased tracers. I will then present an analytical model to describe the velocity prifile around massive clusters and its potential to probe modified gravity.
