Feb 5, 2015 · The Planck full mission cosmic microwave background(CMB) temperature and E-mode polarization maps are analysed to obtain constraints on primordial non- ...
One of the main goals of this paper is to improve NG constraints using mainly the angular bispectrum of CMB anisotropies, i.e., the harmonic transform of the 3- ...
The results are based on comprehensive cross-validation of these estimators on Gaussian and non-Gaussian simulations, are stable across component separation ...
