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 Radio Synchrotron Morphology, Spectra, and Polarization of Cosmic Ray Driven Galactic Winds
H. -H. Sandy Chiu, Mateusz Ruszkowski, Timon Thomas +2
The formation of galaxies is significantly influenced by galactic winds, possibly driven by cosmic rays due to their long cooling times and better coupling to plasma compared to ra…
