Description
Large scale structure in the universe causes gravitational lensing of
the cosmic microwave background (CMB), which has now been
well-measured by several CMB experiments. By cross-correlating CMB
lensing with tracers of large scale structure (like galaxies), it is
possible to obtain new constraints on cosmology and a better
understanding of possible systematic errors in cosmological probes.
I will discuss the theoretical formulation, methods used in estimating
errors, systematic checks to verify robustness, and cosmological
implications of cross-correlations between CMB lensing and galaxy
surveys, and will present recent results of cross-correlation analyses.
