Impact of beam far side-lobe knowledge in the presence of foregrounds for LiteBIRD

C. Leloup, G. Patanchon, J. Errard +108

We present a study of the impact of an uncertainty in the beam far side-lobe knowledge on the measurement of the Cosmic Microwave Background -mode signal at large scale. It is e…

LiteBIRD Science Goals and Forecasts: Improving Sensitivity to Inflationary Gravitational Waves with Multitracer Delensing

T. Namikawa, A. I. Lonappan, C. Baccigalupi +119

We estimate the efficiency of mitigating the lensing -mode polarization, the so-called delensing, for the experiment with multiple external data sets of lensing-mass…

LiteBIRD Science Goals and Forecasts: A full-sky measurement of gravitational lensing of the CMB

A. I. Lonappan, T. Namikawa, G. Piccirilli +119

We explore the capability of measuring lensing signals in full-sky polarization maps. With a arcmin beam width and an impressively low polarization noise of $2.16\,…

Zero-polarization candidate regions for calibration of wide-field optical polarimeters

N. Mandarakas, G. V. Panopoulou, V. Pelgrims +14

Context. Calibration of optical polarimeters relies on the use of stars with negligible polarization (unpolarized standard stars) for determining the instrumental polarization zero…

LiteBIRD Science Goals and Forecasts. A Case Study of the Origin of Primordial Gravitational Waves using Large-Scale CMB Polarization

P. Campeti, E. Komatsu, C. Baccigalupi +107

We study the possibility of using the satellite -mode survey to constrain models of inflation producing specific features in CMB angular power spectra. We explore a p…

Bright-Moon Sky as a Wide-Field Linear Polarimetric Flat Source for Calibration

S. Maharana, S. Kiehlmann, D. Blinov +20

Next-generation wide-field optical polarimeters like the Wide-Area Linear Optical Polarimeters (WALOPs) have a field of view (FoV) of tens of arcminutes. For efficient and accurate…
