Results of two simulations of a 100 ks XRISM observation zoomed in on the blueshifted Fe K absorption signature. The X-ray continuum consists of a power law modified by Galactic absorption. Top panel: the UFO absorption feature is modeled with a single broad absorption Gaussian line. Bottom panel: the broad absorption line is superseded by five narrow Gaussian absorption lines to test the capabilities of XRISM’s Resolve calorimeter to detect structures within the outflow profile.
