KODIAQ-Z: Metals and Baryons in the Cool Intergalactic and Circumgalactic Gas at 2.2<z<3.6
Nicolas Lehner, Claire Kopenhafer, John O'Meara +8
We present the KODIAQ-Z survey aimed to characterize the cool, photoionized gas at 2.2<z<3.6 in 202 HI-selected absorbers with 14.6<log N(HI)<20, i.e., the gaseous interface betwee…
The physics of gas phase metallicity gradients in galaxies
Piyush Sharda, Mark R. Krumholz, Emily Wisnioski +3
We present a new model for the evolution of gas phase metallicity gradients in galaxies from first principles. We show that metallicity gradients depend on four ratios that collect…
On the origin of the mass-metallicity gradient relation in the local Universe
Piyush Sharda, Mark R. Krumholz, Emily Wisnioski +3
In addition to the well-known gas phase mass-metallicity relation (MZR), recent spatially-resolved observations have shown that local galaxies also obey a mass-metallicity gradient…
