Rapid Quenching of Galaxies at Cosmic Noon
Minjung Park, Sirio Belli, Charlie Conroy +6
The existence of massive quiescent galaxies at high redshift seems to require rapid quenching, but it is unclear whether all quiescent galaxies have gone through this phase and wha…
Formation of Galactic Disks II: the Physical Drivers of Disk Spin-up
Vadim A. Semenov, Charlie Conroy, Vedant Chandra +2
Using a representative sample of Milky Way (MW)-like galaxies from the TNG50 cosmological simulation, we investigate physical processes driving the formation of galactic disks. A d…
Birth of the Galactic Disk Revealed by the H3 Survey
Charlie Conroy, David H. Weinberg, Rohan P. Naidu +12
We use chemistry ([alpha/Fe] and [Fe/H]), main sequence turnoff ages, and kinematics determined from H3 Survey spectroscopy and Gaia astrometry to identify the birth of the Galacti…
Star Formation Shut Down by Multiphase Gas Outflow in a Galaxy at a Redshift of 2.45
Sirio Belli, Minjung Park, Rebecca L. Davies +15
Large-scale outflows driven by supermassive black holes are thought to play a fundamental role in suppressing star formation in massive galaxies. However, direct observational evid…
Extending the Chemical Reach of the H3 Survey: Detailed Abundances of the Dwarf-galaxy Stellar Stream Wukong/LMS-1
Guilherme Limberg, Alexander P. Ji, Rohan P. Naidu +10
We present the first detailed chemical-abundance analysis of stars from the dwarf-galaxy stellar stream Wukong/LMS-1 covering a wide metallicity range ($-3.5 < \rm[Fe/H] \lesssim -…
