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 ZekoviÄ, 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…
