Spectral Imaging with QUBIC: building frequency maps from Time-Ordered-Data using Bolometric Interferometry

M. Regnier, T. Laclavère, J-Ch. Hamilton +34

The search for relics from the inflation era in the form of B-mode polarization of the CMB is a major challenge in cosmology. The main obstacle appears to come from the complexity…

Intracluster Medium Fluctuations on Scales up to 1 Mpc: A Combined eROSITA and SPT/Planck Analysis of Abell 3266

H. Saxena, A. Heinrich, J. Sayers +22

Galaxy clusters form through hierarchical assembly, where smaller substructures merge to build the largest gravitationally bound objects in the universe. These mergers, combined wi…

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…

Spectral Imaging with QUBIC: building astrophysical components from Time-Ordered-Data using Bolometric Interferometry

M. Regnier, T. Laclavere, J-Ch. Hamilton +33

The detection of B-modes in the CMB polarization pattern is a major issue in modern cosmology and must therefore be handled with analytical methods that produce reliable results. W…

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…

KISS: instrument description and performance

J. F. Macías-Pérez, M. Fernández-Torreiro, A. Catalano +35

Kinetic inductance detectors (KIDs) have been proven as reliable systems for astrophysical observations, especially in the millimetre range. Their compact size enables to optimally…
