XMAGNET -- Stir before serving: a Lagrangian perspective on mixing-driven condensation in the intracluster medium
M. Fournier, P. Grete, M. Brüggen +4
We aim to characterize the thermodynamic and dynamical conditions leading to condensation in cluster cores, and to assess the role of magnetic fields. We implement a Monte-Carlo tr…
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…
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…
