Description
I will outline the ways in which cosmological observations of large-scale
structure can test departures from LCDM or, more generally, apparent violations of
general relativity. These observations include a broad variety of cosmological
probes that are now being exploited by spectroscopic and photometric
surveys. I will focus on the basics physics behind these probes, and end with
the outline of the formalism that compares the geometrical and growth aspects
of LSS that can provide a very general stress-test of the cosmological model.
