Probing early structure and model-independent neutrino mass with high-redshift CMB lensing mass maps
Probing early structure and model-independent neutrino mass with high-redshift CMB lensing mass maps
CMB lensing maps probe the mass distribution in projection out to high redshifts, but significant sensitivity to low-redshift structure remains. In this paper we discuss a method to remove the low-redshift contributions from CMB lensing mass maps by subtracting suitably scaled galaxy density maps, nulling the low redshift structure with …
