TL;DR: The IBIS telescope as mentioned in this paper is the high angular resolution gamma-ray imager on-board the INTEGRAL Observatory, which was successfully launched from Baikonur (Kazakhstan) the 17th of October 2002.

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 Imaging X-ray Polarimetry Explorer (IXPE) as mentioned in this paper is an international collaboration for a scientific mission that dramatically brings together the unique talents of the partners to expand observation space by simultaneously adding polarization measurements to the array of source properties currently measured (energy, time, and location).

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 X-ray Imaging Polarimetry Explorer (XIPE) as mentioned in this paper was proposed in 2012 to the first ESA call for a small mission with a launch in 2017, but the proposal was, unfortunately, not selected.
