Can CMB Lensing Help Cosmic Shear Surveys?
Can CMB Lensing Help Cosmic Shear Surveys?
Yes! Upcoming galaxy shear surveys have the potential to significantly improve our understanding of dark energy and neutrino mass if lensing systematics can be sufficiently controlled. The cross-correlations between the weak lensing shear, galaxy number counts from a galaxy redshift survey, and the CMB lensing convergence can be used to …
