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…
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…
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 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 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…
