Probing Cosmic Ray Transport with Radio Synchrotron Harps in the Galactic Center
Timon Thomas, Christoph Pfrommer, Torsten A. Enßlin
Recent observations with the MeerKAT radio telescope reveal a unique population of faint non-thermal filaments pervading the central molecular zone (CMZ). Some of those filaments a…
Braginskii viscosity on an unstructured, moving mesh accelerated with super-time-stepping
Thomas Berlok, Ruediger Pakmor, Christoph Pfrommer
We present a method for efficiently modelling Braginskii viscosity on an unstructured, moving mesh. Braginskii viscosity, i.e., anisotropic transport of momentum with respect to th…
Magnetising the circumgalactic medium of disk galaxies
Ruediger Pakmor, Freeke van de Voort, Rebekka Bieri +7
The circumgalactic medium (CGM) is one of the frontiers of galaxy formation and intimately connected to the galaxy via accretion of gas on to the galaxy and gaseous outflows from t…
The effects of cosmic rays on the formation of Milky Way-mass galaxies in a cosmological context
Tobias Buck, Christoph Pfrommer, Rüdiger Pakmor +2
We investigate the impact of cosmic rays (CR) and different modes of CR transport on the properties of Milky Way-mass galaxies in cosmological magneto-hydrodynamical simulations in…
Spectrally resolved cosmic ray hydrodynamics -- I. Spectral scheme
Philipp Girichidis, Christoph Pfrommer, Michal Hanasz +1
Cosmic ray (CR) protons are an important component in many astrophysical systems. Processes like CR injection, cooling, adiabatic changes as well as active CR transport through the…
The impact of magnetic fields on cold streams feeding galaxies
Thomas Berlok, Christoph Pfrommer
High redshift, massive halos are observed to have sustained, high star formation rates, which require that the amount of cold gas in the halo is continuously replenished. The cooli…
