Local non-Gaussianity in the Cosmic Microwave Background the Bayesian way
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/27
We introduce an exact Bayesian approach to search for non-Gaussianity of local type in Cosmic Microwave Background (CMB) radiation data. Using simulated CMB temperature maps, the newly developed techn...
Non-Gaussianity and the Cosmic Microwave Background Anisotropies
Non-Gaussianity Cosmic Microwave
2010/3/19
We review in a pedagogical way the present status of the impact of non-Gaussianity (NG) on the Cosmic Microwave Background (CMB) anisotropies. We first show how to set the initial conditions at second...
