The Impact of Molecular Hydrogen Cooling on the Galaxy Formation Threshold

open access: yesThe Astrophysical Journal Letters
We study the impact of molecular (H _2 ) and atomic (H i ) hydrogen cooling on the galaxy formation threshold. We calculate the fraction of dark matter (DM) halos that exceeds a critical mass required for star formation, M _crit ( z ), as a function of ...

Widespread Rapid Quenching at Cosmic Noon Revealed by JWST Deep Spectroscopy

open access: yesThe Astrophysical Journal
Massive quiescent galaxies in the young Universe are expected to be quenched rapidly, but it is unclear whether they all experience starbursts before quenching and what physical mechanism drives rapid quenching. We study 14 massive quiescent galaxies ( $\

Exploring Lenticular Galaxy Formation in Field Environments Using NewHorizon: Evidence for Counterrotating Gas Accretion as a Formation Channel

open access: yesThe Astrophysical Journal
The formation pathways of lenticular galaxies (S0s) in field environments remain a matter of debate. We utilize the cosmological hydrodynamic simulation, NewHorizon , to investigate the issue. We select two massive star formation quenched S0s as our main
