Validation of harmonic-space likelihood methods for LiteBIRD B-mode polarisation analysis

G. Galloni, P. Campeti, C. Gimeno-Amo +112

The LiteBIRD satellite mission aims to measure the tensor-to-scalar ratio with unprecedented sensitivity through observations of the cosmic microwave background (CMB) -mode…

Combining Systematic Effects in CMB Polarization Experiments through map-based simulations: application to LiteBIRD's HWP non-idealities and detectors non-linearity

Silvia Micheli, Francesco Piacentini, Tommaso Ghigna +10

We quantify the impact of coupled instrumental systematics on next-generation CMB polarization experiments targeting primordial -mode polarization, with a focus on the forthcomi…

A cross-calibration approach for polarisation-sensitive detectors in CMB experiments: application to LiteBIRD's polarisation angle calibration

A. Novelli, F. Piacentini, S. Micheli +102

We present a cross-calibration algorithm that determines the relative calibration of detectors within the same frequency band of a CMB experiment. The method iteratively compares s…

Intracluster Medium Fluctuations on Scales up to 1 Mpc: A Combined eROSITA and SPT/Planck Analysis of Abell 3266

H. Saxena, A. Heinrich, J. Sayers +22

Galaxy clusters form through hierarchical assembly, where smaller substructures merge to build the largest gravitationally bound objects in the universe. These mergers, combined wi…

Mitigating half-wave plate systematics at the map-making level: calibration requirements for LiteBIRD

N. Raffuzzi, A. Carones, M. Monelli +101

Although half-wave plates (HWPs) are becoming a popular choice of polarization modulators for cosmic microwave background (CMB) experiments, their non-idealities can introduce syst…

LiteBIRD Science Goals and Forecasts. -mode Anomalies

A. J. Banday, C. Gimeno-Amo, P. Diego-Palazuelos +101

Various so-called anomalies have been found in both the WMAP and Planck cosmic microwave background (CMB) temperature data that exert a mild tension against the highly successful b…

LiteBIRD science goals and forecasts: improved full-sky reconstruction of the gravitational lensing potential through the combination of Planck and LiteBIRD data

M. Ruiz-Granda, P. Diego-Palazuelos, C. Gimeno-Amo +102

Cosmic microwave background (CMB) photons are deflected by large-scale structure through gravitational lensing. This secondary effect introduces higher-order correlations in CMB an…

Requirements on bandpass resolution and measurement precision for LiteBIRD

S. Giardiello, A. Carones, T. Ghigna +95

In this work, we study the impact of an imperfect knowledge of the instrument bandpasses on the estimate of the tensor-to-scalar ratio in the context of the next-generation Lit…

LiteBIRD Science Goals and Forecasts: constraining isotropic cosmic birefringence

E. de la Hoz, P. Diego-Palazuelos, J. Errard +112

Cosmic birefringence (CB) is the rotation of the photons' linear polarisation plane during propagation. Such an effect is a tracer of parity-violating extensions of standard electr…

Exploring Cosmic Origins with CORE: B-mode Component Separation

M. Remazeilles, A. J. Banday, C. Baccigalupi +113

We demonstrate that, for the baseline design of the CORE satellite mission, the polarized foregrounds can be controlled at the level required to allow the detection of the primordi…
