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

N. Raffuzzi, A. Carones, M. Monelli, S. Giardiello et autres

Abstract Although half-wave plates (HWPs) are becoming a popular choice of polarization modulators for cosmic microwave background (CMB) experiments, their non-idealities can introduce systematic effects that should be carefully characterized and mitigated. One possible mitigation strategy is to incorporate information about the …

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, P. Vielva et autres

Abstract Cosmic microwave background (CMB) photons are deflected by large-scale structure through gravitational lensing. This secondary effect introduces higher-order correlations in CMB anisotropies, which are used to reconstruct lensing deflections. This allows mapping of the integrated matter distribution along the line of …

First release of LiteBIRD simulations from an end-to-end pipeline

M. Bortolami, N. Raffuzzi, L. Pagano, Giuseppe Puglisi et autres

Abstract The LiteBIRD satellite mission aims at detecting Cosmic Microwave Background B modes with unprecedented precision, targeting a total error on the tensor-to-scalar ratio r of δr ∼ 0.001. Operating from the L2 Lagrangian point of the Sun-Earth system, LiteBIRD will survey …

LiteBIRD science goals and forecasts: constraining isotropic cosmic birefringence

E. de la Hoz, P. Diego-Palazuelos, Josquin Errard, A. Gruppuso et autres

Abstract 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 electromagnetism and would probe the existence of a new cosmological field acting as dark matter or …

LiteBIRD science goals and forecasts. Mapping the hot gas in the Universe

M. Remazeilles, M. Douspis, J.A. Rubiño-Martín, A. J. Banday et autres

Abstract We assess the capabilities of the LiteBIRD mission to map the hot gas distribution in the Universe through the thermal Sunyaev-Zeldovich (SZ) effect. Our analysis relies on comprehensive simulations incorporating various sources of Galactic and extragalactic foreground emission, while accounting for …

LiteBIRD science goals and forecasts: primordial magnetic fields

D. Paoletti, J. A. Rubiño-Martín, Maresuke Shiraishi, D. Molinari et autres

Abstract We present detailed forecasts for the constraints on the characteristics of primordial magnetic fields (PMFs) generated prior to recombination that will be obtained with the LiteBIRD satellite. The constraints are driven by some of the main physical effects of PMFs on …

We describe the processing of data from the Low Frequency Instrument (LFI) used in production of the Planck Early Release Compact Source Catalogue (ERCSC). In particular, we discuss the steps involved in reducing the data from telemetry packets to cleaned, calibrated, time-ordered …
