Measuring the CMB primordial B-modes with Bolometric Interferometry
View through CrossRef
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 systematic effects that is typical of interferometry, both key features in the quest for the faint signal of the primordial B-modes. A unique feature is the so-called “spectral imaging”, i.e., the ability to recover the sky signal in several sub-bands within the physical band during data analysis. This feature provides an in-band spectral resolution of ∆v/v ~ 0.04 that is unattainable by a traditional imager. This is a key tool for controlling the Galactic foregrounds contamination. In this paper, we describe the principles of bolometric interferometry, the current status of the QU BIC experiment and future prospects.

Title: Measuring the CMB primordial B-modes with Bolometric Interferometry
Description:
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 systematic effects that is typical of interferometry, both key features in the quest for the faint signal of the primordial B-modes.
A unique feature is the so-called “spectral imaging”, i.
e.
, the ability to recover the sky signal in several sub-bands within the physical band during data analysis.
This feature provides an in-band spectral resolution of ∆v/v ~ 0.
04 that is unattainable by a traditional imager.
This is a key tool for controlling the Galactic foregrounds contamination.
In this paper, we describe the principles of bolometric interferometry, the current status of the QU BIC experiment and future prospects.
