Likelihood methods for CMB experiments
Martina Gerbino, Massimiliano Lattanzi, Marina Migliaccio +6
A great deal of experimental effort is currently being devoted to the precise measurements of the cosmic microwave background (CMB) sky in temperature and polarisation. Satellites,…
Planck 2018 results. V. CMB power spectra and likelihoods
Planck Collaboration, N. Aghanim, Y. Akrami +165
This paper describes the 2018 Planck CMB likelihoods, following a hybrid approach similar to the 2015 one, with different approximations at low and high multipoles, and implementin…
Planck 2018 results. VII. Isotropy and Statistics of the CMB
Planck Collaboration, Y. Akrami, M. Ashdown +147
Analysis of the Planck 2018 data set indicates that the statistical properties of the cosmic microwave background (CMB) temperature anisotropies are in excellent agreement with pre…
Planck 2018 results. IX. Constraints on primordial non-Gaussianity
Planck Collaboration, Y. Akrami, F. Arroja +157
We analyse the Planck full-mission cosmic microwave background (CMB) temperature and E-mode polarization maps to obtain constraints on primordial non-Gaussianity (NG). We compare e…
On the tension between Large Scale Structures and Cosmic Microwave Background
Marian Douspis, Laura Salvati, Nabila Aghanim
Recent years have brought strong observational evidences for the standard LCDM cosmological model. Cosmic microwave background (CMB) anisotropy and large scale structure (LSS) prob…
Mass bias evolution in tSZ cluster cosmology
Laura Salvati, Marian Douspis, Anna Ritz +2
Galaxy clusters observed through the thermal Sunyaev-Zeldovich (tSZ) effect are a recent cosmological probe. The precision on the cosmological constraints is affected mainly by the…
