Joint resonant CMB power spectrum and bispectrum estimation
P. Daniel Meerburg, Moritz Münchmeyer, Benjamin Wandelt
We develop the tools necessary to assess the statistical significance of resonant features in the CMB correlation functions, combining power spectrum and bispectrum measurements. T…
Optimal CMB estimators for bispectra from excited states
P. Daniel Meerburg, Moritz Münchmeyer
We propose optimal estimators for bispectra from excited states. Two common properties of such bispectra are the enhancement in the collinear limit, and the prediction of oscillati…
Planck 2015 results. XX. Constraints on inflation
Planck Collaboration, P. A. R. Ade, N. Aghanim +244
We present the implications for cosmic inflation of the Planck measurements of the cosmic microwave background (CMB) anisotropies in both temperature and polarization based on the…
Planck 2015 results. XVII. Constraints on primordial non-Gaussianity
Planck Collaboration, P. A. R. Ade, N. Aghanim +239
The Planck full mission cosmic microwave background(CMB) temperature and E-mode polarization maps are analysed to obtain constraints on primordial non-Gaussianity(NG). Using three…
