Multi-Clustering Needlet-ILC for CMB B-modes component separation
Alessandro Carones, Marina Migliaccio, Giuseppe Puglisi +4
The Cosmic Microwave Background (CMB) primordial B-modes signal is predicted to be much lower than the polarized Galactic emission (foregrounds) in any region of the sky pointing t…
Minkowski Functionals of CMB polarisation intensity with Pynkowski: theory and application to Planck and future data
Alessandro Carones, Javier Carrón Duque, Domenico Marinucci +2
The angular power spectrum of the Cosmic Microwave Background (CMB) anisotropies is a key tool to study the Universe. However, it is blind to the presence of non--Gaussianities and…
Analysis of NILC performance on B-modes data of sub-orbital experiments
Alessandro Carones, Marina Migliaccio, Domenico Marinucci +1
The observation of primordial B-modes in the Cosmic Microwave Background (CMB) represents the main scientific goal of most of the future CMB experiments. This signal is predicted t…
Updated constraints on amplitude and tilt of the tensor primordial spectrum
Giacomo Galloni, Nicola Bartolo, Sabino Matarrese +3
We have taken a comprehensive approach to update the limits on the tensor-to-scalar ratio () and the tensor spectral index (), using 10 datasets from the BICEP/Keck Array 2…
Test of the Statistical Isotropy of the Universe using Gravitational Waves
Giacomo Galloni, Nicola Bartolo, Sabino Matarrese +3
Since WMAP and Planck some anomalous features appeared in the Cosmic Microwave Background (CMB) large-angle anisotropy, the so-called anomalies. One of these is the hemispherical p…
Probing Cosmic Inflation with the LiteBIRD Cosmic Microwave Background Polarization Survey
LiteBIRD Collaboration, E. Allys, K. Arnold +188
LiteBIRD, the Lite (Light) satellite for the study of B-mode polarization and Inflation from cosmic background Radiation Detection, is a space mission for primordial cosmology and…
