M87_NW
We propose a mosaic of XRISM/Resolve pointings designed to study supermassive black hole feedback in the nearest and second brightest cool core cluster in spatially resolved detail. The most striking features in M87 are the 6 arcmin-long, X-ray bright arms thought to be filaments of multi-phase, metal-rich gas uplifted by the buoyant AGN radio lobes. XRISM measurements will reveal the kinematics of this uplift and quantify the amount of metals being transported outwards by the AGN. The relatively low ambient temperature of M87 corresponds to a line-rich spectrum that will perfectly showcase the soft X-ray capabilities of Resolve.
