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…
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…
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…
Measuring the CMB primordial B-modes with Bolometric Interferometry
A. Mennella, P. Ade, A. Almela +111
The Q&U Bolometric Interferometer for Cosmology (QUBIC) is the first bolometric interferometer designed to measure the primordial B-mode polarization of the Cosmic Microwave Backgr…
Tensor-to-scalar ratio forecasts for extended LiteBIRD frequency configurations
U. Fuskeland, J. Aumont, R. Aurlien +114
LiteBIRD is a planned JAXA-led CMB B-mode satellite experiment aiming for launch in the late 2020s, with a primary goal of detecting the imprint of primordial inflationary gravitat…
Polarization angle requirements for CMB B-mode experiments. Application to the LiteBIRD satellite
P. Vielva, E. Martínez-González, F. J. Casas +68
A methodology to provide the polarization angle requirements for different sets of detectors, at a given frequency of a CMB polarization experiment, is presented. The uncertainties…
Spectral Distortions of the CMB as a Probe of Inflation, Recombination, Structure Formation and Particle Physics
J. Chluba, A. Kogut, S. P. Patil +98
Following the pioneering observations with COBE in the early 1990s, studies of the cosmic microwave background (CMB) have focused on temperature and polarization anisotropies. CMB…
Forecast analysis and focal plane optimization for a multi-frequency CMB B-modes polarization experiment: the case of LSPE
Roberto Mainini, Massimo Gervasi, Mario Zannoni +1
We present an optimization scheme for the focal plane of a multi-frequency CMB B-modes experiment with a fixed number of detectors and apply it to the specific case of LSPE experim…
An improved upper limit to the CMB circular polarization at large angular scales
R. Mainini, D. Minelli, M. Gervasi +7
Circular polarization of the Cosmic Microwave Background (CMB) offers the possibility of detecting rotations of the universe and magnetic fields in the primeval universe or in dist…
A template of atmospheric molecular oxygen circularly polarized emission for CMB experiments
Giulio Fabbian, Sebastiano Spinelli, Massimo Gervasi +2
We compute the polarized signal from atmospheric molecular oxygen due to Zeeman effect in the Earth magnetic field for various sites suitable for CMB measurements such as South Pol…
Cosmological observations in the radio domain: the contribution of extragalactic sources
Andrea Tartari, Mario Zannoni, Massimo Gervasi +2
The low frequency tail of the CMB spectrum, down along the radio range (~1 GHz), may carry weak spectral distortions which are fingerprints of processes occurred during different e…
SAGACE: the Spectroscopic Active Galaxies And Clusters Explorer
P. De Bernardis, D. Bagliani, A. Bardi +42
The SAGACE experiment consists of a mm/sub-mm telescope with a 3-m diameter primary mirror, coupled to a cryogenic multi-beam differential spectrometer. SAGACE explores the sky in…
