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…

Identifying heating processes in simulations with an entropy-based scheme: A single jet episode in a galaxy cluster

Moun Meenakshi, Rainer Weinberger, Christoph Pfrommer +1

Understanding heating processes in galaxy clusters is essential for predicting the regulation of radiative cooling and star formation, and for clarifying the mechanisms underlying…

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…
