Implementation of frequency-correlated noise in CMB component separation: Method, Validation, and Early Applications

L. Zapelli, M. Bersanelli, L. P. L. Colombo, A. Mennella et autres

Parametric component separation methods used in cosmic microwave background (CMB) analyses commonly assume instrumental noise to be uncorrelated between frequency channels. This approximation may become insufficient for experiments whose design naturally introduces cross-channel correlations, such as interferometric or multi-band bolometric systems. This …

Performance of the QUBIC CMB telescope's detectors

S. Marwede, C O’Sullivan, A. B. Flood, D. Gayer et autres

The Theory of Inflation postulates that, immediately after the Big Bang, the Universe expanded exponentially. If this theory is true, the resulting gravitational waves must have left traces in the CMB in the form of an extremely faint B-mode polarisation pattern. The …

The effect of QUBIC beam uncertainty on the reconstruction of the CMB B-mode power spectrum

A. B. Flood, C. O’Sullivan, M. L. Gradziel, D. Gayer et autres

The cosmic microwave background (CMB) is microwave radiation from the Big Bang which permeates the entire observable universe. Inflation, a brief period of exponential expansion in the early universe, is predicted to have imprinted an extremely faint polarization signature, known as the …

Measuring the CMB primordial B-modes with Bolometric Interferometry

ANIELLO MENNELLA, Peter A. R. Ade, Alejandro Almela, G. Amico et autres

The Q&U Bolometric Interferometer for Cosmology (QL’BIC) is the first bolometric interferometer designed to measure the primordial B-mode polarization of the Cosmic Microwave Background (CMB). Bolometric interferometry is a novel technique that combines the sensitivity of bolometric detectors with the control of …

QUBIC – The Q & U Bolometric Interferometer for Cosmology

C. O’Sullivan, David P. Burke, M. De Petris, Marcin Gradziel et autres

This In this paper we briefly describe QUBIC, the Q & U Bolometric Interferometer for Cosmology, a novel ground-based instrument designed to measure the extremely faint polarization anisotropy of the cosmic microwave background at intermediate angular scales. In particular we will describe …

Status of QUBIC, the Q&U Bolometer for Cosmology

L. Mousset, P. Ade, Alejandro Almela, G. Amico et autres

The Q&U Bolometric Interferometer for Cosmology (QUBIC) is a novel kind of polarimeter optimized for the measurement of the B-mode polarization of the Cosmic Microwave Back-ground (CMB), which is one of the major challenges of observational cosmology. The signal is expected to …
