Accelerated Galaxy Growth and Environmental Quenching in a Protocluster at z = 3.24 [PDF]

open access: yesAstrophysical Journal, 2021
We present a multiwavelength study of galaxies around D4UD01, a spectroscopically confirmed protocluster at z = 3.24, to investigate environmental trends. 450 galaxies are selected based on K S band detection with photometric redshifts (photo-z) at 3.0 <

Investigating the Dominant Environmental Quenching Process in UVCANDELS/COSMOS Groups

open access: yesThe Astrophysical Journal, 2023
We explore how the fraction of quenched galaxies changes in groups of galaxies with respect to the distance to the center of the group, redshift, and stellar mass to determine the dominant process of environmental quenching in 0.2 < z < 0.8 groups.

MOSFIRE Spectroscopy of Quiescent Galaxies at 1.5 < z < 2.5. II. Star Formation Histories and Galaxy Quenching [PDF]

open access: yesAstrophysical Journal, 2018
We investigate the stellar populations for a sample of 24 quiescent galaxies at 1.5 < z < 2.5 using deep rest-frame optical spectra obtained with Keck MOSFIRE.

CLEAR: The Morphological Evolution of Galaxies in the Green Valley

open access: yesThe Astrophysical Journal, 2023
Quiescent galaxies having more compact morphologies than star-forming galaxies has been a consistent result in the field of galaxy evolution. What is not clear is at what point this divergence happens, i.e., when do quiescent galaxies become compact, and

Mass and Environment as Drivers of Galaxy Evolution. IV. On the Quenching of Massive Central Disk Galaxies in the Local Universe [PDF]

open access: yesAstrophysical Journal, 2021
The phenomenological study of evolving galaxy populations in Peng et al. has shown that star forming galaxies can be quenched by two distinct processes: mass quenching and environment quenching. To explore the mass quenching process in local galaxies, we

AGN-driven quenching of satellite galaxies [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2019
ABSTRACT We explore the effect of active galactic nucleus (AGN) feedback from central galaxies on their satellites by comparing two sets of cosmological zoom-in runs of 27 haloes with masses ranging from 1012 to 1013.4$\rm {M}_{\odot}$ at z = 0, with (wAGN) and without (noAGN) AGN feedback.

Bar quenching in gas-rich galaxies [PDF]

open access: yesAstronomy & Astrophysics, 2018
Galaxy surveys have suggested that rapid and sustained decrease in the star-formation rate (SFR), “quenching”, in massive disk galaxies is frequently related to the presence of a bar. Optical and near-IR observations reveal that nearly 60% of disk galaxies in the local universe are barred, thus it is important to understand the relationship between ...

The Roles of Mass and Environment in the Quenching of Galaxies [PDF]

open access: yesThe Astrophysical Journal, 2019
Abstract We study the roles of stellar mass and environment in quenching the star formation activity of a large set of simulated galaxies by taking advantage of an analytic model coupled to the merger tree extracted from an N-body simulation. The analytic model has been set to match the evolution of the global stellar mass function since

Quenching star formation in cluster galaxies [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2014
In order to understand the processes that quench star formation within rich clusters, we construct a library of subhalo orbits drawn from $ $CDM cosmological N-body simulations of four rich clusters. The orbits are combined with models of star formation followed by quenching in the cluster environment.
