FOSSIL: A future mission for CMB spectral distortion measurements

N. Aghanim, B. Maffei, J. Aumont +96

We present FOSSIL, a proposed space mission which is designed to deliver unprecedented absolute spectroscopic measurements of the sky intensity over a broad frequency range (50GHz…

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…

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…

Non-Gaussianity in SMICA

M. Citran, H. V. Tran, G. Patanchon +1

We develop a new formalism for the component separation method Spectral Matching Independent Component Analysis (SMICA) in order to include the information contained in the foregro…

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…

Constraints on primordial non-Gaussianity from Planck PR4 data

Gabriel Jung, Michele Citran, Bartjan van Tent +2

We perform the first bispectrum analysis of the final Planck release temperature and E-polarization CMB data, called PR4. We use the binned bispectrum estimator pipeline that was a…

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…
