Place:	Seminar Room A
Abstract:	Galaxy redshift surveys hold the promise of containing the largest amount of cosmological information among all of the cosmological probes, but this relies on understanding the connection between the galaxies and the dark matter clustering. I will discuss topics related to this connection. Among these is the galaxy biasing, where I will show evidence for its non-locality and non-linearity. I will also discuss the issue of shot noise, arguing that it is more complicated than the standard model. Finally, I will discus the redshift space distortions presenting a physically motivated model that can explain many of the properties seen in simulations.
