Description
We investigate the transformation of cool-core (CC) clusters into non-cool-core (NCC) systems during cluster mergers, incorporating both active galactic nucleus (AGN) feedback and radiative cooling. Using three-dimensional hydrodynamic simulations implemented with the GAMER (v2) code, we explore how mergers affect the entropy evolution of CC clusters. By varying key parameters such as mass ratios and impact parameters, we examine the relative contributions of merger-driven heating and AGN feedback in regulating CC stability. Our analysis focuses on the entropy evolution, the interplay between AGN jets and intracluster medium (ICM) turbulence, and the cooling–heating balance in cluster cores. This study provides physical insights into the mechanisms that disrupt cool cores and offers a theoretical framework to interpret the observed diversity of cluster thermal states in cosmological surveys.
