| Abstract: | Understanding the cosmic cycle of baryons and metals is central to unraveling the evolution of structure in the Universe. The intracluster medium (ICM) in galaxy clusters serves as a unique laboratory for studying both the dynamics of large-scale structure formation and the history of chemical enrichment across cosmic time. In this talk, I will present recent insights into the circulation of mass and metals in the Universe, enabled by the unprecedented spectral resolution of the XRISM (X-Ray Imaging and Spectroscopy Mission) Resolve instrument. I will focus on how XRISM”Æs high-resolution X-ray spectroscopy allows us to probe the kinematics of the ICM”Ŗrevealing bulk motions, turbulence, and feedback processes”Ŗas well as trace the distribution and origin of heavy elements synthesized in stars and supernovae. In addition to cluster environments, I will highlight a few key results from other astrophysical targets, including active galactic nuclei and supernova remnants, showcasing XRISM”Æs broad impact on our understanding of energetic processes and chemical evolution in the cosmos. |
