Description
The precision to which we can constrain cosmological parameters is limited by sampling variance and shot noise. I will discuss the extent to which systematics in the shot noise modelling affect measurements of GR projection effects and fNL with the multi-tracer technique, and how these measurements could be optimized.I will also present measurements of the halo shot noise in halo bispectra along with theoretical predictions based on the halo model.
