Illuminating M82: Simulating X-ray Emission from Galactic Winds in a Starburst Galaxy
Allison Lin, Lachlan Lancaster, Viraj Pandya +6
We generate mock X-ray observations from a suite of idealized high-resolution ( pc), tall-box ( kpc) simulations of star formation driven gala…
Introducing sapphire: Towards Hybrid Physics-Informed, Data-Driven Modeling of Galaxy Formation
Viraj Pandya, Greg L. Bryan, T. Lucas Makinen +18
Semi-analytic models (SAMs) have been treating galaxy populations as dynamical systems for years, but their evolution equations remain poorly constrained. We introduce…
Dynamical Origins of Azimuthal Metallicity Variations in the Galactic Disk: Insights from Kinematic Ridges with Gaia
Carlos Jurado, Keith Hawkins, Jason A. S. Hunt +4
Kinematic and spectroscopic studies in the past few years have revealed coherent azimuthal metallicity variations across the Milky Way's disk that may be the result of dynamical pr…
Azimuthal metallicity variations, spiral structure, and the failure of radial actions based on assuming axisymmetry
Victor P. Debattista, Tigran Khachaturyants, Joao A. S. Amarante +3
We study azimuthal variations in the mean stellar metallicity, <[Fe/H]>, in a self-consistent, isolated simulation in which all stars form out of gas. We find <[Fe/H]> variations c…
