Lagrangian tracers show mixing with low-entropy seeds drives most condensation in cluster cores; magnetic fields cause earlier divergence, higher vorticity, lower Mach numbers, and slower cold-cloud motion via tension.
An idealized simulation of a relaxed Perseus-like cluster shows that combined jet-wind AGN feedback, with GRMHD-constrained properties, reproduces key observables by boosting heating efficiency through shear-driven turbulence.
Multi-frequency radio data supports Abell 980 as hosting a detached double-double radio galaxy formed by two jet episodes from the BCG with subsequent lateral drift causing loss of lobe colinearity.
UV background suppresses NEI in galaxy haloes, restoring equilibrium shock thresholds and producing extended absorption columns for OVI, CIV, and HI beyond the virial radius.
