Extragalactic Science with XRISM

XRISM, an international JAXA/NASA collaboration including participation from ESA, is an advanced X-ray observatory that will address some of the most important questions in astrophysics in the 2020s. Launched on September 5, 2022, XRISM has two instruments: Resolve, a high-resolution, non-dispersive X-ray spectrometer, providing high-resolution (~5 eV), imaging spectroscopic capability; and Xtend, a wide field imager that offers simultaneous coverage over a ~40 arcmin square field of view, with ~1′ angular resolution. This talk will highlight some of the scientific topics that XRISM will address, with emphasis on extragalactic X-ray sources: active and starburst galaxies and clusters of galaxies.
