XMAGNET : Kinetic, Thermal and Magnetic AGN Feedback in Massive Galaxies at Halo Masses M
Deovrat Prasad, Philipp Grete, Brian O'Shea +5
The interplay between radiative cooling of the circumgalactic medium (CGM) and feedback heating governs the evolution of the universe's most massive galaxies. This paper presents s…
Precipitation plausible: magnetized thermal instability in the intracluster medium
Benjamin D. Wibking, G. Mark Voit, Brian W. O'Shea
Observations of galaxy-cluster cores reveal that AGN feedback is strongly associated with both a short central cooling time () and accumulation…
XMAGNET: Velocity structure functions of active galactic nucleus-driven turbulence in the multiphase intracluster medium
M. Fournier, P. Grete, M. Brüggen +5
Significant theoretical and observational efforts are underway to investigate the properties of turbulence in the hot plasma that pervades galaxy clusters. Spectroscopy has been us…
The XMAGNET exascale MHD simulations of SMBH feedback in galaxy groups and clusters: Overview and preliminary cluster results
Philipp Grete, Brian W. O'Shea, Forrest W. Glines +5
We present initial results from extremely well-resolved 3D magnetohydrodynamical simulations of idealized galaxy clusters, conducted using the AthenaPK code on the Frontier exascal…
Precipitation possible: turbulence-driven thermal instability with constrained entropy profiles
Benjamin D. Wibking, G. Mark Voit, Brian W. O'Shea
Precipitation of cold gas due to thermal instability in both galaxy clusters and the circumgalactic medium may regulate AGN feedback. We investigate thermal instability in idealize…
The properties of magnetised cold filaments in a cool-core galaxy cluster
Martin Fournier, Philipp Grete, Marcus Brüggen +2
Filaments of cold gas ( K) are found in the inner regions of many cool-core clusters. These structures are thought to play a major role in the regulation of feedback…
The Case for Hot-Mode Accretion in Abell 2029
Deovrat Prasad, G. Mark Voit, Brian W. O'Shea
Radiative cooling and AGN heating are thought to form a feedback loop that regulates the evolution of low redshift cool-core galaxy clusters. Numerical simulations suggest that for…
A Black-Hole Feedback Valve in Massive Galaxies
G. M. Voit, G. L. Bryan, D. Prasad +6
Star formation in the universe's most massive galaxies proceeds furiously early in time but then nearly ceases. Plenty of hot gas remains available but does not cool and condense i…
Circumgalactic Gas and the Precipitation Limit
G. M. Voit, A. Babul, Iu. Babyk +15
During the last decade, numerous and varied observations, along with increasingly sophisticated numerical simulations, have awakened astronomers to the central role the circumgalac…
Triggering and Delivery Algorithms for AGN Feedback
Gregory R. Meece, G. Mark Voit, Brian W. O'Shea
We compare several common sub-grid implementations of AGN feedback, focusing on the effects of different triggering mechanisms and the differences between thermal and kinetic feedb…
Cooling, AGN Feedback and Star Formation in Simulated Cool-Core Galaxy Clusters
Yuan Li, Greg L. Bryan, Mateusz Ruszkowski +3
Numerical simulations of active galactic nuclei (AGN) feedback in cool-core galaxy clusters have successfully avoided classical cooling flows, but often produce too much cold gas.…
