Statistical analysis of the relative orientations between filaments and magnetic fields using Herschel and Planck data in star-forming regions

Jonathan Oers, Isabelle Ristorcelli, Katia Ferrière +4

Observations and simulations of the interstellar medium both suggest that magnetic fields play a key role in the formation and evolution of filaments and in the process of star for…

Status of the COSmological Microwave Observations CALibrator

L. Mousset, J. Aumont, S. Berta +33

As the sensitivity of CMB telescopes increases, the need for precise calibration becomes critical. Started in 2022, the COSMOCal project aims to place an artificial polarized sourc…

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…
