Abstract

Supermassive black holes (SMBH) interact with gas in the interstellar and intergalactic media (ISM/IGM) in a process termed “feedback” that is key to the formation and evolution of galaxies and clusters. Characterizing the origins and physical mechanisms governing this feedback requires tracing the propagation of outflowing mass, energy and momentum from the vicinity of the SMBH out to megaparsec scales. Our ability to understand the interplay between feedback and structure evolution across multiple scales, as well as a wide range of other important astrophysical phenomena, depends on diagnostics only available in soft x-ray spectra (10-50 Å). Arcus combines high-resolution, efficient, lightweight x-ray gratings with silicon pore optics to provide R~2500 with an average effective area of ~200 cm2, an order of magnitude larger than the Chandra gratings. Flight-proven CCDs and instrument electronics are strong heritage components, while spacecraft and mission operations also reuse highly successful designs.

Arcus:探索星团、星系和恒星的形成和演化

超大质量黑洞(SMBH)与星际和星系间介质(ISM/IGM)中的气体在一个被称为“反馈”的过程中相互作用，这是星系和星团形成和演化的关键。描述起源和控制这种反馈的物理机制需要追踪从SMBH附近流出的质量、能量和动量的传播到百万秒差距尺度。我们理解反馈和结构演变之间的相互作用的能力，以及其他广泛的重要天体物理现象，依赖于仅在软x射线光谱中可用的诊断(10-50 Å)。Arcus将高分辨率、高效、轻便的x射线光栅与硅孔光学相结合，提供R~2500的平均有效面积为~200 cm2，比钱德拉光栅大一个数量级。经过飞行验证的ccd和仪器电子设备是强大的传统组件，而航天器和任务操作也重复使用非常成功的设计。
