AGN-ICM study: XRISM feasibility study of the cores of the A3391/95 clusters and X-ray morphological properties of eRASS1-EMU radio pilot survey cluster sample

The A3391/95 clusters harbor bright central radio sources, which makes them ideal objects to probe the ICM-AGN interaction. The future JAXA/NASA/ESA mission, the X-Ray Imaging and Spectroscopy Mission (XRISM) will enable us to resolve line emission and the motion of the ICM affected by AGN feedback. Through simulation using cluster properties obtained from eROSITA and XMM-Newton, a forecast of the best observing strategy for XRISM high-resolution spectroscopy will be made. Given the complexity of the system, we will probe their merger state, as well. We further extend the central AGN-ICM study to a larger sample, namely using the first eROSITA All-Sky Survey (eRASS1) cluster sample in the EMU pilot field using the Australian ASKAP radio telescopes. We present preliminary results of the X-ray morphological properties of this sample.
Athena will complete the AGN-ICM study, for instance, to investigate in great detail the chemical distribution and central cluster gas motion due to the central AGN feedback.
