Constraining primordial non-Gaussianity by combining photometric galaxy and 21 cm intensity mapping surveys
Abstract The fluctuations produced during cosmic inflation may exhibit non-Gaussian characteristics that are imprinted in the large-scale structure of the Universe. This non-Gaussian imprint is an ultra-large scale signal that can be detected using the power spectrum. We focus on the local-type non-...
