A multi-scale view of molecular gas and magnetic fields in the Antennae galaxies
Akhil Lasrado, Enrique Lopez-Rodriguez, Claudia Cicone +5
Major mergers are transformative events in galaxy evolution, dynamically reshaping the stellar and gas makeup of the hosts, as well as the galaxy-scale magnetic fields (B-fields) t…
Fast, Stable, and Physical: Hyperbolic, Magnetic Field-Aligned Diffusion in SPH
Nicholas Owens, James Wadsley, Robert Wissing +1
In this paper, we introduce the first implementation of magnetic field-aligned hyperbolic diffusion for standard smoothed particle (magneto-)hydrodynamics (SPH), and its linear-exa…
EuroHPC SPACE CoE: Redesigning Scalable Parallel Astrophysical Codes for Exascale
Nitin Shukla, Alessandro Romeo, Caterina Caravita +36
High Performance Computing (HPC) based simulations are crucial in Astrophysics and Cosmology (A&C), helping scientists investigate and understand complex astrophysical phenomena. T…
The LISA Astrophysics "Disc-IMRI" Code Comparison Project: Intermediate-Mass-Ratio Binaries in AGN-Like Discs
Andrea Derdzinski, Alexander J. Dittmann, Alessia Franchini +16
Upcoming space-based gravitational wave detectors such as LISA, the Laser Interferometer Space Antenna, will be sensitive to extreme- and intermediate-mass-ratio inspirals (EMRIs a…
In-Situ High Performance Visualization for Astronomy & Cosmology
Nicola Tuccari, Eva Sciacca, Yolanda Becerra +4
The Astronomy & Cosmology (A&C) community is presently witnessing an unprecedented growth in the quality and quantity of data coming from simulations and observations. Writing resu…
The Seven Dwarfs illuminated. The impact of radiation on dwarf galaxies and their circumgalactic medium
Bernhard Baumschlager, Sijing Shen, James W. Wadsley +6
We present a high-resolution cosmological zoom-in simulation of a group of field dwarf galaxies which includes on-the-fly radiative transfer (RT) and is evolved to . Emission…
Optimized smoothing kernels for SPH
Robert Wissing, Thomas R. Quinn, Ben Keller +2
We present a set of new smoothing kernels for smoothed particle hydrodynamics (SPH) that improve the convergence of the method without any additional computational cost. These kern…
Axisymmetric smoothed particle magneto-hydrodynamics
Domingo García-Senz, Robert Wissing, Rubén M. Cabezón +2
Many astrophysical and terrestrial scenarios involving magnetic fields can be approached in axial geometry. Although the smoothed particle hydrodynamics (SPH) technique has been su…
Numerical dependencies of the galactic dynamo in isolated galaxies with SPH
Robert Wissing, Sijing Shen
Understanding the numerical dependencies that act on the galactic dynamo is a crucial step in determining what resolution and what conditions are required to properly capture the m…
Axisymmetric magneto-hydrodynamics with SPH
Domingo García-Senz, Robert Wissing, Rubén M. Cabezón
Many interesting terrestrial and astrophysical scenarios involving magnetic fields can be approached in axial geometry. Even though the Lagrangian smoothed particle hydrodynamics (…
