Non-Gaussianity of secondary anisotropies from ACTPol and Planck
Non-Gaussianity of secondary anisotropies from ACTPol and Planck
Most secondary sources of cosmic microwave background anisotropy (radio sources, dusty galaxies, thermal Sunyaev Zel'dovich distortions from hot gas, and gravitational lensing) are highly non-Gaussian. Statistics beyond the power spectrum are therefore potentially important sources of information about the physics of these processes. We combine data from the Atacama Cosmology …
