The diverse nature of spiral arms in the Auriga Superstars cosmological hydrodynamic simulations

Robert J J Grand, Francesca Fragkoudi, Rüdiger Pakmor +4

The dynamical nature and formation mechanism(s) of galactic spiral arms remain long-standing problems in astrophysics. Most theoretical work is based on analytic calculations or id…

Environment matters: stronger magnetic fields in satellite galaxies

Maria Werhahn, Rüdiger Pakmor, Rebekka Bieri +3

Magnetic fields are ubiquitous in the universe and an important component of the interstellar medium. It is crucial to accurately model and understand their properties in different…

Stellar-gas kinematic misalignments in EAGLE: enhanced SMBH growth in misaligned galaxies

Maximilian K. Baker, Timothy A. Davis, Freeke van de Voort +1

Stellar-gas kinematic misalignments are a transient phenomenon observed in of the local galaxy population. According to current models, misaligned gas is expected to los…

Stellar-gas kinematic misalignments in EAGLE: lifetimes and longevity of misaligned galaxies

Maximilian K. Baker, Timothy A. Davis, Freeke van de Voort +1

The dominant processes by which galaxies replenish their cold gas reservoirs remain disputed, especially in massive galaxies. Stellar-gas kinematic misalignments offer an opportuni…

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…

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…
