Merging galaxies and clusters: Insights into the role of magnetic fields and the physics of radio relics

Joseph Whittingham

Mergers have long been understood to be a driver of galaxy and galaxy cluster evolution. They release tremendous amounts of gravitational potential energy - ~ and ~$10^{64…

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…

Zooming in on radio relics -- II. How relic morphology probes density fluctuations at the edge of galaxy clusters

Joseph Whittingham, Christoph Pfrommer, Maria Werhahn +2

Gas properties in the outer intracluster medium (ICM) are not well-constrained, as traditional probes lose sensitivity at Mpc distances. We show that the morphology of radio relics…

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…
