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…
FEASTS Compared with Simulations: Abnormally Irregular and Extended HI Morphologies at a Column Density of in TNG50 and Auriga
Xuchen Lin, Jing Wang, Guinevere Kauffmann +2
With new atomic-hydrogen (HI) observations of FAST Extended Atlas of Selected Targets Survey (FEASTS), we present the first statistical comparison of HI morphology between observat…
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…
Co-evolution of baryons and dark matter halos of LYRA dwarf galaxies
Joaquin Sureda, Shaun T. Brown, Azadeh Fattahi +4
We use the extremely high-resolution () LYRA cosmological galaxy formation simulations of six dwarf galaxies with at…
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…
