Title: The Q&U Bolometric Interferometer for Cosmology (QUBIC): status and perspectives
Abstract: QUBIC (Q & U Bolometric Interferometer for Cosmology) is an international ground-based experiment dedicated in the measurement of the polarized fluctuations of the millimeter sky and especially the Cosmic Microwave Background (CMB). It is based on bolometric interferometry, an original detection technique which combine the immunity to systematic effects of an interferometer with the sensitivity of low temperature incoherent detectors. QUBIC is currently in commissioning in Argentina, at the Alto Chorrillos mountain site at 5000m a.s.l. near San Antonio de los Cobres, in the Salta province. After a description of the QUBIC instrument, I will present the last results of the first characterization phases with a focus on the detectors and readout system based on NbSi Transition Edge Sensors (TESs) cooled to 320mK. The perspective of spectro-imaging will also be described allowing for better foreground mitigation. This feature will soon be tested with QUBIC and could represent a significant breakthrough in CMB polarimetry.
