The role of mass and environment in the build-up of the quenched galaxy population since cosmic noon. Monthly Notices of the Royal Astronomical Society, 522(2), 2297-2306. https://doi.org/10.1093/mnras/stad1098

We conduct the first study of how the relative quenching probability of galaxies depends on environment over the redshift range 0.5 < z < 3, using data from the UKIDSS Ultra-Deep Survey. By constructing the stellar mass functions for quiescent and po... Read More about The role of mass and environment in the build-up of the quenched galaxy population since cosmic noon.

We present rest-frame optical emission-line flux ratio measurements for five z > 5 galaxies observed by the James Webb Space Telescope Near-Infared Spectrograph (NIRSpec) in the SMACS 0723 Early Release Observations. We add several quality-control an... Read More about The Physical Conditions of Emission-line Galaxies at Cosmic Dawn from JWST/NIRSpec Spectroscopy in the SMACS 0723 Early Release Observations.

Dusty Starbursts Masquerading as Ultra-high Redshift Galaxies in JWST CEERS Observations (2023)

Lyman-break galaxy (LBG) candidates at z ≳ 10 are rapidly being identified in James Webb Space Telescope (JWST)/NIRCam observations. Due to the (redshifted) break produced by neutral hydrogen absorption of rest-frame UV photons, these sources are exp...
