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…

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…

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 $…
