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…

A Morphology Catalog of Galaxies in CEERS: Evolution in the Size and Color Gradients of Galaxies Since Cosmic Dawn

Elizabeth J. McGrath, Steven L. Finkelstein, Guillermo Barro +42

We present measurements of morphological parameters from fitting 53,885 galaxies detected to a magnitude limit of F356W in the CEERS NIRCam imaging with galfit in six broad…

Second public data release of the FIRE-2 cosmological zoom-in simulations of galaxy formation

Andrew Wetzel, Jenna Samuel, Pratik J. Gandhi +34

We describe the second data release (DR2) of the FIRE-2 cosmological zoom-in simulations of galaxy formation, from the Feedback In Realistic Environments (FIRE) project, available…

Evaluating Mass Outflow Rate Estimators in FIRE-2 Simulations: Towards a Self-Consistent Framework for Spectral Line Based Predictions

Cody A Carr, Aaron Smith, Viraj Pandya +4

$\require{mediawiki-texvc}$Galactic outflows shape galaxy evolution, but their mass, energy, and momentum transfer remain uncertain. High-resolution spectroscopy can help, but syst…
