JAXA-led new X-ray space telescope XRISM is going to launch soon to study cosmic violent events. X-rays are emitted by extremely hot and energetic objects, such as colliding gas between galaxies. XRISM stands for “X-Ray Imaging and Spectroscopy Mission”. The X-ray calorimeter, a device that measures X-ray photon energies by detecting temperature changes, will enable astronomers to identify the chemical elements in various astrophysical phenomena. It can also study large objects, such as galaxy clusters and supernova remnants, beyond pointlike sources. XRISM studies super-hot gas envelopes around galaxy clusters using X-rays. How galaxies are shaped by violent outbursts from monster black holes at their centers, how different chemical elements are distributed in the universe, and the history of the universe. The launch is scheduled for Monday, August 28, 2023 09:26 Japan time, from Tanegashima Japan.
