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…
Requirements on the gain calibration for LiteBIRD polarisation data with blind component separation
F. Carralot, A. Carones, N. Krachmalnicoff +106
Future cosmic microwave background (CMB) experiments are primarily targeting a detection of the primordial -mode polarisation. The faintness of this signal requires exquisite co…
LiteBIRD Science Goals and Forecasts. Mapping the Hot Gas in the Universe
M. Remazeilles, M. Douspis, J. A. Rubiño-Martín +104
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 compreh…
LiteBIRD Science Goals and Forecasts: Primordial Magnetic Fields
D. Paoletti, J. Rubino-Martin, M. Shiraishi +97
We present detailed forecasts for the constraints on primordial magnetic fields (PMFs) that will be obtained with the LiteBIRD satellite. The constraints are driven by the effects…
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\,…

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…
Cosmoglobe DR1 results. II. Constraints on isotropic cosmic birefringence from reprocessed WMAP and Planck LFI data
J. R. Eskilt, D. J. Watts, R. Aurlien +28
Cosmic birefringence is a parity-violating effect that might have rotated the plane of linearly polarized light of the cosmic microwave background (CMB) by an angle since its e…
