Core of the Centaurus cluster and its XRISM/Resolve and XMM-Newton/RGS extraction regions. The full-array Resolve FoV (excluding pixels 12 and 27; Sect. 2.1.1) is shown in solid green contours while the cross-dispersion apertures of RGS (0.8′ and 3′) chosen for this work are shown in yellow (dashed and solid contours, respectively). Left: Exposure-corrected 0.3–7 keV Chandra/ACIS fluxed image showing the soft X-ray features of NGC 4696 (plume, cavities). Right: XMM-Newton/EPIC MOS 2 counts image showing the gas extent at larger scale. Detected point sources (red circles) fall mostly outside of our regions and are thus negligible.
