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 High Energy Transmission Grating (HETG) has been used at the Chandra X-Ray Observatory (Chandra X-ray Observatory) for 5 years of flight experience as discussed by the authors.

TL;DR: The High Energy Transmission Grating (HETG) has been used at the Chandra X-ray Observatory for five years of flight experience as discussed by the authors, and has been successfully used for ground testing and calibration.

TL;DR: In this paper, the authors propose a contract with the U.S. National Aeronautics and Space Administration (Nasa) for the development of a satellite communications system.

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.
