微量热计在提供炎热和高能宇宙的高光谱分辨率观测方面取得了显著的成功，并为X射线天文学中革命性的新科学可能性铺平了道路。紧凑天体科学中有几个研究领域只能用能量分辨率ΔE≲ 5 eV在几千电子伏特的光子能量下进行，对应于每秒低于几百公里的速度分辨率，由微热量计引入。在这里，我们回顾了一些悬而未决的问题，重点是如何在吸积超大质量黑洞与其所在星系之间的界面上改变研究格局，在揭示吸积环境的结构方面，在解决关于能量和物质反馈起源的长期问题方面，在检验吸积和反馈的质量尺度的统一方面。强调需要从Hitomi吸取经验教训，并在实验室原子数据精度和等离子体建模方面做出改进。
Microcalorimeters have shown remarkable success in delivering high-spectral-resolution observations of the hot and energetic Universe, and have paved the way to revolutionary new science possibilities in X-ray astronomy. There are several research areas in compact-object science that can only be addressed with energy resolution ΔE≲ 5 eV at photon energies of a few kiloelectronvolts, corresponding to a velocity resolution of less than a few hundred kilometres per second, to be ushered in by microcalorimeters. Here we review some of the outstanding questions, focusing on how the research landscape is set to be transformed at the interface between accreting supermassive black holes and their host galaxies, in unravelling the structures of accretion environments, in resolving long-standing issues on the origins of energy and matter feedback, and in testing mass-scaled unification of accretion and feedback. The need to learn lessons from Hitomi and to make improvements in laboratory atomic data precision as well as plasma modelling are highlighted.
