Summary

Description Per A spectra comparison.png	English: The X-ray spectrum observed by Hitomi's Soft X-ray Imaging Spectrometer (SXS) reveals never-before-seen details of the million-degree gas filling the Perseus galaxy cluster. For comparison, a dashed red line shows the best previous observation using the Suzaku satellite's X-ray Imaging Spcetrometer (XIS). The area enlarged at right is shown on a logarithmic scale to highlight some of the important emission lines detected at higher energies. Top left: An X-ray image from NASA's Chandra X-ray Observatory reveals the hot gas filling the Perseus galaxy cluster. The square indicates the area targeted by Hitomi.
