A High-Resolution Look at Cosmic Metals: What XRISM Reveals About the Centaurus Cluster Core

Using high-resolution XRISM/Resolve data, Mernier et al. measure the chemical composition of the Centaurus cluster core with unprecedented precision. Most element-to-iron ratios are close to solar, but nitrogen is enhanced and magnesium is depleted compared to the Solar System. These differences suggest that cluster cores may not share a universal chemical composition and reflect variations in stellar enrichment histories.
