论文摘要
宇宙学(Qubic)的Q&U骨测量干涉仪是一种优化的新型偏振仪,用于测量宇宙微波后地面B模式极化(CMB),这是观察宇宙学的主要挑战之一。该信号有望达到数十万个NK的顺序,容易产生仪器系统效应,并受到各种天体物理前景污染,这些前景只能通过多核电观测来控制。 Qubic旨在通过一种新型方法来解决这些观察性问题,该方法将干涉仪的优势与宽带探测器的控制范围探测器相结合,以宽波段的宽带,背景限制的灵敏度。
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 be of the order of a few tens of nK, prone to instrumental systematic effects and polluted by various astrophysical foregrounds which can only be controlled through multichroic observations. QUBIC is designed to address these observational issues with a novel approach that combines the advantages of interferometry in terms of control of instrumental systematics with those of bolometric detectors in terms of wide-band, background-limited sensitivity.
