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…
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…
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…
Magnetized Decaying Turbulence in the Weakly Compressible Taylor-Green Vortex
Forrest W. Glines, Philipp Grete, Brian W. O'Shea
Magnetohydrodynamic turbulence affects both terrestrial and astrophysical plasmas. The properties of magnetized turbulence must be better understood to more accurately characterize…
Environmental Dependence of Self-Regulating Black-hole Feedback in Massive Galaxies
Deovrat Prasad, G. Mark Voit, Brian W. O'shea +1
In the universe's most massive galaxies, kinetic feedback from a central supermassive black hole appears to limit star formation. Abundant circumstantial evidence suggests that acc…
Tests of AGN Feedback Kernels in Simulated Galaxy Clusters
Forrest W. Glines, Brian W. O'Shea, G. Mark Voit
In cool-core galaxy clusters with central cooling times much shorter than a Hubble time, condensation of the ambient central gas is regulated by a heating mechanism, probably an ac…
K-Athena: a performance portable structured grid finite volume magnetohydrodynamics code
Philipp Grete, Forrest W. Glines, Brian W. O'Shea
Large scale simulations are a key pillar of modern research and require ever-increasing computational resources. Different novel manycore architectures have emerged in recent years…
