TL;DR: In this paper, the authors summarized the spacecraft, in-orbit performance, operations, and data processing that are related to observations of the Suzaku X-ray observatory, including high-sensitivity wide-band Xray spectroscopy.

TL;DR: In this article, a framework for the Monte-Carlo simulation of X-Ray Telescopes (XRT) and X-ray Imaging Spectrometers (XIS) onboard Suzaku was developed for the scientific analysis of spatially and spectroscopically complex celestial sources.

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: In this article, the authors constructed an X-ray non-X-ray background (NXB) database by collecting XIS events when the dark Earth covers the XIS FOV and found that the count rate of the NXB anti-correlates with the cut-off-rigidity and correlates with the PIN upper discriminator (PIN-UD).

TL;DR: In this article, the energy spectrum and the large-scale fluctuation of the X-ray background with the ASCA GIS instrument based on ASCA Medium Sensitivity Survey and Large Sky Survey observations were studied.
