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) -- 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…
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…
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…
When are galactic winds molecular?
Aditi Vijayan, Mark R. Krumholz
The molecular phase of supernova-driven outflows originates from the cold, molecular gas in the disc of a star-forming galaxy, and may carry a substantial fraction of the wind mass…
Quokka-based Understanding of Outflows (QED) I. Metal loading, phase structure, and convergence testing for Solar neighbourhood conditions
Aditi Vijayan, Mark R. Krumholz, Benjamin D. Wibking
Multiphase galactic outflows, generated by supernova feedback, are likely to be more metal-rich than the interstellar media from which they are driven due to incomplete mixing betw…
X-ray Emission from the Interstellar and Circumgalactic Medium of Elliptical Galaxies based on MACER simulations
Aditi Vijayan, Bocheng Zhu, Miao Li +2
Interstellar (ISM) and circumgalactic mediums (CGM) around galaxies are linked to several physical processes that drive galaxy evolution. For example, the X-ray emission from the C…
Radio Halo of NGC 4631: Comparing Observations and Simulations
Aditi Vijayan, K. S. Dwarakanath, Biman B. Nath +1
We present low frequency observations at and MHz from the upgraded Giant Metrewave Radio Telescope (uGMRT) of the edge-on, nearby galaxy NGC . We compare the obse…
X-ray Spectra of Circumgalactic Medium Around Star-Forming Galaxies: Connecting Simulations to Observations
Aditi Vijayan, Miao Li
The hot component of the circum-galactic medium (CGM) around star forming galaxies is detected as diffuse X-ray emission. The X-ray spectra from the CGM depend on the temperature a…
Kinematics and Dynamics of Multiphase Outflows in Simulations of the Star-Forming Galactic ISM
Aditi Vijayan, Chang-Goo Kim, Lucia Armillotta +2
Galactic outflows produced by stellar feedback are known to be multiphase in nature. Both observations and simulations indicate that the material within several kpc of galactic dis…
Radio halos of star forming galaxies
Aditi Vijayan, Biman B. Nath, Prateek Sharma +1
We study the synchrotron radio emission from extra-planar regions of star forming galaxies. We use ideal magneto-hydrodynamical (MHD) simulations of a rotating Milky Way-type disk…
Extra-planar X-ray emission from disc-wide outflows in spiral galaxies
Aditi Vijayan, Kartick C. Sarkar, Biman B. Nath +2
We study the effects of mass and energy injection due to OB associations spread across the rotating disc of a Milky Way-type galaxy, with the help of 3D hydrodynamic simulations. W…
