The assembly history of NGC 1365 through chemical archaeology

Lisa J. Kewley, Kathryn Grasha, Alex Garcia +8

Galaxies build through infalling gas and galaxy mergers. Tracking the dynamical history of a galaxy from a single snapshot in time is notoriously difficult. We show that the dynami…

Metallicity Gradients in Modern Cosmological Simulations I: Tension Between Smooth Stellar Feedback Models and Observations

Alex M. Garcia, Paul Torrey, Aniket Bhagwat +14

The metallicity of galaxies, and its variation with galactocentric radius, provides key insights into the formation histories of galaxies and the physical processes driving their e…

Star Formation Rates, Metallicities, and Stellar Masses on kpc-scales in TNG50

Jia Qi, Alex M. Garcia, Davis Robinson +7

Integral field units (IFU) have extended our knowledge of galactic properties to kpc (or, sometimes, even smaller) patches of galaxies. These scales are where the physics driving g…

SLAMS-Propelled Electron Acceleration at High-Mach Number Astrophysical Shocks

Vladimir Zeković, Anatoly Spitkovsky, Zachary Hemler

Short Large Amplitude Magnetic Structures (SLAMS) are frequently detected during spacecraft crossings over the Earth bow shock. We investigate the existence of such structures at a…

Does the Fundamental Metallicity Relation Evolve with Redshift? II: The Evolution in Normalisation of the Mass-Metallicity Relation

Alex M. Garcia, Paul Torrey, Sara L. Ellison +10

The metal content of galaxies is a direct probe of the baryon cycle. A hallmark example is the relationship between a galaxy's stellar mass, star formation rate (SFR), and gas-phas…

Does the Fundamental Metallicity Relation Evolve with Redshift? I: The Correlation Between Offsets from the Mass-Metallicity Relation and Star Formation Rate

Alex M. Garcia, Paul Torrey, Sara Ellison +8

The scatter about the mass-metallicity relation (MZR) has a correlation with the star formation rate (SFR) of galaxies. The lack of evidence of evolution in correlated scatter at $…

Interplay of Stellar and Gas-Phase Metallicities: Unveiling Insights for Stellar Feedback Modeling with Illustris, IllustrisTNG, and EAGLE

Alex M. Garcia, Paul Torrey, Kathryn Grasha +6

The metal content of galaxies provides a window into their formation in the full context of the cosmic baryon cycle. In this study, we examine the relationship between stellar mass…

Gas-phase metallicity break radii of star-forming galaxies in IllustrisTNG

Alex M. Garcia, Paul Torrey, Z. S. Hemler +6

We present radial gas-phase metallicity profiles, gradients, and break radii at redshift from the TNG50-1 star-forming galaxy population. These metallicity profiles are…

Gas-phase metallicity gradients of TNG50 star-forming galaxies

Z. S. Hemler, Paul Torrey, Jia Qi +8

We present the radial gas-phase, mass-weighted metallicity profiles and gradients of the TNG50 star-forming galaxy population measured at redshifts 0--3. We investigate the re…
