Viewing the ins and outs of black hole accretion with XRISM

Abstract

The Resolve microcalorimeter on XRISM provides unprecedented energy resolution in the Fe K band of AGN. In several objects, we resolve multiple components in the iron emission lines indicating origins from the inner wall of the torus, the broad-line region, and regions much closer to the black hole. Highly-ionised, clumpy or stratified, multiphase winds are observed, and the ultrafast outflow nature of some are confirmed. Here, we will present observations of AGN (e.g NGC 4151, Cen A, M81*) in various accretion states observed with XRISM during the performance verification phase and highlight how material is falling inward and being ejected in these systems. The power of XRISM demonstrates the Fe K region is an effective probe of the accretion flow in AGN.
