Anisotropic cosmic birefringence estimates for forthcoming CMB experiments
Matteo Longo Minnolo, Matteo Billi, Giuseppe Puglisi
Cosmic Birefringence (CB) is a unique probe of physics beyond the Standard Model, potentially sourced by an axion-like field coupled to photons via a Chern-Simons interaction. Rece…
The anomaly of the CMB power with the latest Planck data
M. Billi, R. B. Barreiro, E. Martínez-González
The lack of power anomaly is an unexpected feature observed at large angular scales in the CMB maps produced by the COBE, WMAP and Planck satellites. This signature, which consists…
Impact of half-wave plate systematics on the measurement of cosmic birefringence from CMB polarization
Marta Monelli, Eiichiro Komatsu, Alexandre E. Adler +6
Polarization of the cosmic microwave background (CMB) can probe new parity-violating physics such as cosmic birefringence (CB), which requires exquisite control over instrumental s…
Planck constraints on cross-correlations between anisotropic cosmic birefringence and CMB polarization
Marco Bortolami, Matteo Billi, Alessandro Gruppuso +2
Cosmic Birefringence (CB) is the in-vacuo rotation of the linear polarization direction of photons during propagation, caused by parity-violating extensions of Maxwell electromagne…
Probing frequency-dependent half-wave plate systematics for CMB experiments with full-sky beam convolution simulations
Adriaan J. Duivenvoorden, Alexandre E. Adler, Matteo Billi +2
We study systematic effects from half-wave plates (HWPs) for cosmic microwave background (CMB) experiments using full-sky time-domain beam convolution simulations. Using an optical…
Polarisation as a tracer of CMB anomalies: Planck results and future forecasts
M. Billi, A. Gruppuso, N. Mandolesi +2
The lack of power anomaly is an intriguing feature at the largest angular scales of the CMB anisotropy temperature pattern, whose statistical significance is not strong enough to c…
