Quokka-based understanding of outflows (QED) -- IV. Limitations of H as an outflow diagnostic
Rongjun Huang, Aditi Vijayan, Mark R. Krumholz
The presence of broad wings in the H line is commonly used as a diagnostic of the presence and properties of galactic winds from star-forming galaxies. However, the accuracy of…
A novel algorithm for GPU-accelerated particle-mesh interactions implemented in the QUOKKA code
Chong-Chong He, Benjamin D. Wibking, Aditi Vijayan +2
We present a novel, GPU-optimized algorithm for particle-mesh interactions in grid-based hydrodynamics simulations, designed for massively parallel architectures. This approach ove…
QED V: Variations in metal loading of galactic winds with element nucleosynthetic origin
Aditi Vijayan, Mark R. Krumholz, Benjamin D. Wibking
Type Ia supernovae, type II supernovae, and asymptotic giant branch (AGB) stars are important sites of stellar nucleosynthesis, but they differ greatly in their rates, their locati…
Quokka-based understanding of outflows (QED) -- II. X-ray metallicity gradients as a signature of galactic wind metal loading
Rongjun Huang, Aditi Vijayan, Mark R. Krumholz
Supernova-driven galactic outflows play a vital but still poorly-understood role in galactic chemical evolution, and one of the largest uncertainties about them is the extent to wh…
QUOKKA-based understanding of outflows (QED) -- III. Outflow loading and phase structure as a function of galactic environment
Aditi Vijayan, Mark R. Krumholz, Benjamin D. Wibking
We present results from a suite of 3D high-resolution hydrodynamic simulations of supernova-driven outflows from galactic disc regions with a range of gas surface density, metallic…
