XRISM Mission Sheds Light on Supermassive Black Holes' Galactic Neighborhoods

The **X-Ray Imaging and Spectroscopy Mission (XRISM)**, a collaboration between the Japanese Aerospace Exploration Agency (JAXA), NASA, and the European Space Agency, is providing unprecedented insights into supermassive black holes and their cosmic surrounds. Launched in September 2023, XRISM uses cutting-edge X-ray spectroscopy to confirm long-theorized complex structures around black holes, known as accretion disks, which are now shown to have twists and warps. With XRISM’s “Resolve” microcalorimeter providing ten times better energy resolution, scientists can finally begin to understand the complex multi-structured environments of black holes. Moreover, XRISM's data allows astrophysicists to explore the orders of magnitude between close-up and zoomed-out views of black holes, filling in the gaps left by previous missions. The mission's success follows previous attempts like Astro-E and Hitomi, underscoring the importance of perseverance in space exploration. Jon Miller from the University of Michigan, key figure in this mission, reflects on the profound impact XRISM is expected to have in advancing our understanding of black holes and their impact on galaxy evolution.
