Abstract

Hot Universe Baryon Surveyor (HUBS) is a proposed space-borne observatory for X-ray astronomy. The primary scientific objectives of the mission are to fill a void in probing the ecosystem of galaxies and thus to advance our understanding of galaxy formation and evolution, which is of fundamental importance in cosmology. More specifically, HUBS aims at directly detecting soft X-ray emission from diffuse gas of temperature exceeding $10^{6}$ K, which is theoretically postulated to permeate the large structures in the cosmic web and also fill the extended halo of galaxies. However, although some indirect evidence exists, the presence of such hot gas has yet to be well established observationally, due to the lack of effective tools to probe it. In this paper, we describe the design of HUBS, focusing on its scientific payload, which employs superconducting technologies in the detector system, and particularly on progress in the development of superconducting microcalorimeters.

用于HUBS任务的超导微热量计的发展

热宇宙重子探测器(HUBS)是一种被提议的用于x射线天文学的星载天文台。该任务的主要科学目标是填补探索星系生态系统的空白，从而推进我们对星系形成和演化的理解，这在宇宙学中是至关重要的。更具体地说，HUBS的目标是直接探测温度超过106 K的弥漫气体发出的软x射线，理论上假设这些气体会渗透到宇宙网中的大型结构中，也会填充星系的延伸晕。然而，尽管存在一些间接证据，由于缺乏有效的探测工具，这种热气体的存在尚未得到很好的观测证实。在本文中，我们描述了hub的设计，重点介绍了其科学有效载荷，它在探测器系统中采用了超导技术，特别是超导微热量计的发展进展。
