(a) XRISM/Resolve (black) and Xtend (red) spectra of 3C 120 in the observed frame, shown together with the best-fit relativistic reflection model. The total model consists of a primary thermal Comptonization continuum (orange), a relativistically blurred reflection component (magenta), and narrow neutral Fe Kα emission lines from distant reflectors, namely the BLR (blue) and dusty torus (green). (b) Close-up view of the XRISM/Resolve spectrum and the best-fit total model in the Fe K region, corrected to the rest frame and shown in units of counts s⁻¹ keV⁻¹ instead of νF_ν. In both panels, the bottom subpanel shows the data-to-model ratios.
