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…
The All-Sky Impact of the LMC on the Milky Way Circumgalactic Medium
Christopher Carr, Greg L. Bryan, Nicolás Garavito-Camargo +3
The first infall of the LMC into the Milky Way (MW) represents a large and recent disruption to the MW circumgalactic medium (CGM). In this work, we use idealized, hydrodynamical s…
Equilibrium States of Galactic Atmospheres II: Interpretation and Implications
G. M. Voit, C. Carr, D. B. Fielding +5
The scaling of galaxy properties with halo mass suggests that feedback loops regulate star formation, but there is no consensus yet about how those feedback loops work. To help cla…
Equilibrium States of Galactic Atmospheres I: The Flip Side of Mass Loading
G. M. Voit, V. Pandya, D. B. Fielding +5
This paper presents a new framework for understanding the relationship between a galaxy and its circumgalactic medium (CGM). It focuses on how imbalances between heating and coolin…
[X/Fe] Marks the Spot: Mapping Chemical Azimuthal Variations in the Galactic Disk with APOGEE
Zoe Hackshaw, Keith Hawkins, Carrie Filion +4
Chemical cartography of the Galactic disk provides insights to its structure and assembly history over cosmic time. In this work, we use chemical cartography to explore chemical gr…
Zooming by in the CARPoolGP lane: new CAMELS-TNG simulations of zoomed-in massive halos
Max E. Lee, Shy Genel, Benjamin D. Wandelt +10
Galaxy formation models within cosmological hydrodynamical simulations contain numerous parameters with non-trivial influences over the resulting properties of simulated cosmic str…
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…
