Active galactic nucleus driven jet feedback in cosmologically forming cool-core galaxy clusters I: The effect of hierarchical assembly on intra-cluster medium properties

Rainer Weinberger, Lorenzo Maria Perrone, Christoph Pfrommer +7

The atmospheres of cool-core galaxy clusters are excellent probes of astrophysical plasmas. However, how the interplay between assembly and active galactic nucleus (AGN) feedback l…

Simulating realistic radio morphologies of Fanaroff-Riley I jets in a self-regulating cool-core cluster

Léna Jlassi, Rainer Weinberger, Christoph Pfrommer +3

Active galactic nucleus (AGN) jets radiate radio synchrotron emission displaying a wide range of morphologies. At the same time, they provide heat to prevent cooling flows in cool-…

Revisiting radio synchrotron diagnostics in star-forming galaxies

Maria Werhahn, Christoph Pfrommer, Philipp Girichidis +7

Radio continuum observations are widely used to study cosmic ray (CR) electron populations and transport processes in star-forming galaxies, but their interpretation relies on seve…

How supermassive black holes shape central entropies in galaxy clusters

Rainer Weinberger, Christoph Pfrommer

A significant fraction of galaxy clusters show central cooling times of less than 1 Gyr and associated central cluster entropies below . We provide…

Simulating cosmic ray electron spectra and radio emission from an AGN jet outburst in a cool-core cluster

Léna Jlassi, Rainer Weinberger, Christoph Pfrommer +3

Active galactic nucleus (AGN) powered jets can accelerate cosmic ray electrons, leading to the observed radio synchrotron emission. To simulate this emission, jet dynamics in galax…

On the Origin of the Ancient, Large-Scale Cold Front in the Perseus Cluster of Galaxies

Elena Bellomi, John ZuHone, Rainer Weinberger +4

The intracluster medium of the Perseus Cluster exhibits spiral-shaped X-ray surface brightness discontinuities known as ``cold fronts'', which simulations indicate are caused by th…

Simulations of the dynamics of magnetised jets and cosmic rays in galaxy clusters

Kristian Ehlert, Rainer Weinberger, Christoph Pfrommer +2

Feedback processes by active galactic nuclei in the centres of galaxy clusters appear to prevent large-scale cooling flows and impede star formation. However, the detailed heating…
