| Abstract: AGN feedback has been considered a key to understanding the cosmic evolution of structures in the Universe. In this work, we utilize the Illustris TNG suite of simulations to investigate the impact of AGN feedback on the thermodynamics of galaxy clusters. We perform a joint fitting of the Sunyaev-Zel'dovich and X-ray signals by combining mock observations from the Atacama Large Millimeter/submillimeter Array (ALMA) and ATHENA/WFI to constrain the thermodynamic properties of the intergalactic medium (IGM) and the intracluster medium (ICM). We propose to use the resulting deprojected radial profiles of electron density, temperature, and pressure to benchmark cosmological volume simulations against real observations obtained from joint ALMA and Chandra analyses. This comparison provides a quantitative test of how efficiently different AGN feedback models redistribute energy and baryons across multiple spatial scales, thereby constraining the impact of different AGN feedback prescriptions on galaxy evolution. Building on previous results obtained from SIMBA (Kar Chowdhury et al., 2022; Chakraborty et al., 2023), we also aim to understand which feedback models best reproduce observed cluster properties, thereby improving the feedback prescriptions used in future cosmological, hydrodynamical simulations. |
