AGN-ICM INTERACTION IN THE INTERACTING CLUSTER SYSTEM A3391/95
We propose conducting high-resolution spectroscopic observations of A3391/95, the unique triple galaxy cluster at z=0.05. Despite sharing a common large-scale structure, these clusters exhibit distinct merger stages and radio emissions, as revealed by eROSITA. Utilizing XRISM, we aim to accurately constrain bulk and turbulent motions at 150 and 200 km/s levels, respectively, and distinguish between the generation processes of gas motions attributed to AGN feedback and merger activity. Comparative analysis with multi-wavelength data and simulations will provide insights into the origins of gas motion and feedback processes within the cluster cores.
