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.
