Constraining local non-Gaussianities with kinetic Sunyaev-Zel’dovich tomography
Constraining local non-Gaussianities with kinetic Sunyaev-Zel’dovich tomography
The authors use the reconstruction of the radial velocity field of matter in the Universe to determine constraints on primordial non-Gaussianities. By cross-correlating future high-resolution CMB and galaxy surveys, the sensitivity for the radial velocity field measurement and thus the constraint on non-Gaussianties can be improved by a factor of …
