TL;DR: The Advanced Telescope for High Energy Astrophysics (Athena+) mission as discussed by the authors provides the necessary performance (e.g., angular resolution, spectral resolution, survey grasp) to address these questions and revolutionize our understanding of the Hot and Energetic Universe.

TL;DR: X-ray observations of the core of the Perseus cluster reveal a remarkably quiescent atmosphere in which the gas has a line-of-sight velocity dispersion of 164 ± 10 kilometres per second in the region 30–60 kiloparsecs from the central nucleus, infering that a total cluster mass determined from hydrostatic equilibrium in a central region would require little correction for turbulent pressure.

TL;DR: The ASTRO-H mission is the sixth in a series of highly successful X-ray missions initiated by the Institute of Space and Astronautical Science (ISAS) as discussed by the authors.

TL;DR: The ASTRO-H mission as discussed by the authors is the sixth in a series of highly successful X-ray missions initiated by the Institute of Space and Astronautical Science (ISAS), and is the first mission to perform high-resolution, high-throughput spectroscopy with moderate angular resolution.

TL;DR: The X-ray Astronomy Recovery Mission (or, XARM) is proposed to regain the key scientific advances anticipated by the international collaboration behind Hitomi by focusing on one of the main science goals of Hitomi,“Resolving astrophysical problems by precise high-resolution X-Ray spectroscopy”.
