Steady-State or Not? The Evolution of Cosmic Ray Electron Spectra in Galaxies
Maria Werhahn, Christoph Pfrommer, Joseph Whittingham +4
Cosmic ray (CR) electrons are key tracers of non-thermal processes in galaxies, yet their spectra are often modelled under the untested assumption of steady state between injection…
Robust magnetic field estimates in star-forming galaxies with the equipartition formula in the absence of equipartition
H. -H. Sandy Chiu, Mateusz Ruszkowski, Maria Werhahn +2
The equipartition model is widely used to estimate magnetic field strength from synchrotron intensity in radio galaxies, yet the validity of its underlying assumptions remains unce…
Unveiling the Impact of Cosmic Rays on the Disc Sizes and Outflows from Dwarf Scales to Galaxy Groups
Rebekka Bieri, Rüdiger Pakmor, Freeke van de Voort +4
Cosmic rays (CRs) are a non-thermal energy component in the interstellar and circumgalactic medium (CGM) that can act as an additional feedback channel beyond thermal and kinetic f…
Auriga Superstars: Improving the resolution and fidelity of stellar dynamics in cosmological galaxy simulations
Ruediger Pakmor, Francesca Fragkoudi, Robert J. J. Grand +7
Cosmological hydrodynamical simulations have become an indispensable tool to understand galaxies. However, computational constraints still severely limit their numerical resolution…
Quantifying the intrinsic variability due to randomness of the Auriga galaxy formation model
Ruediger Pakmor, Rebekka Bieri, Francesca Fragkoudi +6
Numerical simulations have become an indispensable tool in astrophysics. To interpret their results, it is critical to understand their intrinsic variability, that is, how much the…
The role of magnetic fields in ram pressure stripping of satellite galaxies in the circumgalactic medium around massive galaxies
Thomas A. Rintoul, Freeke van de Voort, Andrew T. Hannington +4
The presence of magnetic fields in galaxies and their haloes could have important consequences for satellite galaxies moving through the magnetised circumgalactic medium (CGM) of t…
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…
