Abstract

Ultrafast outflows (UFOs) launched near supermassive black holes (SMBHs) are key to understanding AGN feedback, which is crucial to the co-evolution of galaxies and their central SMBHs. However, the acceleration mechanism remains unclear and is a major open question. During the XRISM PV phase, we observed the AGN-starburst composite system IRAS 05189 2524 and identified at least three UFO components with distinct bulk velocities and velocity widths. In AO2, we propose a 300 ksec follow-up observation to probe variability in each UFO component and investigate correlations with X-ray luminosity. This will provide new insights into the acceleration mechanism and enable robust estimates of outflow properties, which are essential for quantifying AGN feedback and its impact on galaxy evolution.
