XRISM (X-Ray Imaging and Spectroscopy Mission) is an X-ray observatory led by JAXA and NASA. XRISM carries two X-ray observing systems, called Resolve and Xtend. Resolve consists of an X-ray mirror and an X-ray microcalorimeter, while Xtend combines an X-ray mirror with an X-ray CCD. Resolve has high energy resolution of 5 eV at 6 keV X-ray photons, and it is effective even for spatially extended objects since it is a non-dispersive spectrometer. Xtend has a wide field of view of more than 900 arcmin2 (larger than the full moon!). XRISM was successfully launched in September 2023. However, due to a gate valve in front of the microcalorimeter failing to open, Resolve is unfortunately unable to observe X-ray photons below 2 keV. Nevertheless, XRISM observations are yielding exciting results. In this talk, I will present some of the recent results from XRISM.
