<div dir="auto" style="font-size: 14px;"><br>
<b>Abstract:</b> The X-ray Imaging and Spectroscopy Mission (XRISM) was launched by JAXA and NASA in late 2023. XRISM carries onboard the next generation of X-ray instrumentation - the X-ray microcalorimeter. With nearly two orders of magnitude improvement
in spectral resolution over current CCD spectroscopy, XRISM is now revealing the dynamics of hot atmospheres in galaxy clusters. I will review the first results from the performance verification phase and present our Cycle 1 observations of gas motions driven
by AGN feedback in the Ophiuchus cluster.</div>
