The PICO-Cluster Project: presenting the galaxy cluster sample and studying magnetic field growth, Faraday rotation and Braginskii heating
Thomas Berlok, Christoph Pfrommer, Ewald Puchwein +9
Galaxy clusters constitute a microcosm of the Universe and offer a unique laboratory for studying plasma astrophysics, encompassing processes such as cosmic-ray acceleration and no…
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…
You Shall Not Pass! The propagation of low/moderate powered jets through a turbulent interstellar medium
Olga Borodina, Yueying Ni, Jake S. Bennett +6
Feedback from black hole-powered jets has been invoked in many cosmological simulations to regulate star formation and quench galaxies. Despite this, observational evidence of how…
Magnetic dynamos in galaxy clusters: the crucial role of galaxy formation physics at high redshifts
Larissa Tevlin, Thomas Berlok, Christoph Pfrommer +6
Observations of Faraday rotation and synchrotron emission in galaxy clusters imply large-scale magnetic fields with strengths possibly extending back to . Non-ra…
Connecting turbulent velocities and magnetic fields in galaxy cluster simulations with active galactic nuclei jets
Kristian Ehlert, Rainer Weinberger, Christoph Pfrommer +1
The study of velocity fields of the hot gas in galaxy clusters can help to unravel details of microphysics on small-scales and to decipher the nature of feedback by active galactic…
