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.…

The dynamical impact of cosmic rays in the Rhea magnetohydrodynamics simulations
Karin Kjellgren, Philipp Girichidis, Junia Göoller +10
This study explores the dynamical impact of cosmic rays (CRs) in Milky Way-like galaxies using the Rhea simulation suite. Cosmic rays, with their substantial energy density, influe…

Introducing the Rhea simulations of Milky-Way-like galaxies I: Effect of gravitational potential on morphology and star formation
Junia Göller, Philipp Girichidis, Noé Brucy +11
The Milky Way is a complex ecosystem, for which we can obtain detailed observations probing the physical mechanisms determining the interstellar medium. For a detailed comparison w…
