Auriga Streams III: the mass-metallicity relation does not rule out tidal mass loss in Local Group satellites
Alexander H. Riley, Rebekka Bieri, Alis J. Deason +6
The mass-metallicity relation is a fundamental galaxy scaling law that has been extended to the faintest systems in the Local Group. We show that the small scatter in this relation…
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…
In-Transit Data Transport Strategies for Coupled AI-Simulation Workflow Patterns
Harikrishna Tummalapalli, Riccardo Balin, Christine M. Simpson +5
Coupled AI-Simulation workflows are becoming the major workloads for HPC facilities, and their increasing complexity necessitates new tools for performance analysis and prototyping…
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…
Auriga Streams I: disrupting satellites surrounding Milky Way-mass haloes at multiple resolutions
Alexander H. Riley, Nora Shipp, Christine M. Simpson +8
In a hierarchically formed Universe, galaxies accrete smaller systems that tidally disrupt as they evolve in the host's potential. We present a complete catalogue of disrupting gal…
