Spiral-like Features in Galaxy Clusters Driven by AGN Jet Feedback: Evidence from MHD Simulations and X-ray Observations

X-ray observations of galaxy clusters have revealed the presence of spiraling features, found in approximately 95% of cool core (CC) clusters. These features are commonly believed to arise from the motion of the intracluster medium induced by minor mergers. While simulations of Merging clusters have reproduced such features, their limitations (eg, merging is rare in CC clusters) have prompted the investigation of alternative mechanisms. AGN feedback is one such mechanism, and its potential role in driving spiral-like features has been the focus research. We present evidence for spiral-like features in a cosmic ray (CR)-dominated AGN jet feedback simulation of galaxy clusters. Our magnetohydrodynamic simulation shows that jet compression could generate spiral-like features with a scale of ~100 kpc, consistent with some current X-ray observations of CC clusters. We analyzed the results using various projections and compared them with actual X-ray observations from Chandra and XMM-Newton. Our findings suggest that AGN jet feedback can drive spiral-like gas features in galaxy clusters. These findings have important implications for understanding the formation and evolution of galaxy clusters and the role of AGN feedback in shaping their properties.These findings have important implications for understanding the formation and evolution of galaxy clusters and the role of AGN feedback in shaping their properties.These findings have important implications for understanding the formation and evolution of galaxy clusters and the role of AGN feedback in shaping their properties.
