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…
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…
The diffuse gamma-ray sky of a Milky Way analogue: Local diversity and global constraints
Karin Kjellgren, Philipp Girichidis, Maria Werhahn +8
Diffuse gamma-ray emission is a key tracer of cosmic rays (CRs) in galaxies, encoding information about their transport, energetics, and interactions with the interstellar medium.…
Disentangling AGN Feedback and Sloshing in the Perseus Cluster with XRISM: Insights from Simulations
Elena Bellomi, John A. ZuHone, Nhut Truong +10
High-resolution X-ray spectroscopy with XRISM has revealed complex, non-monotonic velocity dispersion profiles in the Perseus cluster, pointing to a complex interplay between at le…
Zooming-in on cluster radio relics -- I. How density fluctuations explain the Mach number discrepancy, microgauss magnetic fields, and spectral index variations
Joseph Whittingham, Christoph Pfrommer, Maria Werhahn +2
It is generally accepted that radio relics are the result of synchrotron emission from shock-accelerated electrons. Current models, however, are still unable to explain several asp…
The theory of resonant cosmic ray-driven instabilities -- Growth and saturation of single modes
Rouven Lemmerz, Mohamad Shalaby, Christoph Pfrommer +1
Cosmic ray (CR) feedback is critical for galaxy formation as CRs drive galactic winds, regularize star formation in galaxies, and escape from active galactic nuclei to heat the coo…
