XRISM Resolve spectrum zoomed-in on the strongest Fe K-shell lines. He-like triplet components are shown: resonance (w), intercombination (x, y), and forbidden (z); Fe XXVI Lyα has α₁ and α₂ transitions. The spectrum is rebinned for clarity. Lower panels: Fit residuals for bapec (red), 2-bapec (blue), and blognorm (green). Minor deviations in Fe XXVI α₂ and Fe XXV intercombination lines resemble those seen in Coma (southern and center pointings), A2029, and Centaurus (XRISM Collaboration 2025a,b,c).
