Bursting and quenching in satellite galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2019 ABSTRACT The difference in stellar metallicity between red and blue galaxies with the same mass constrains the time-scale over which red galaxies ceased to form stars. Here we investigate this constraint with the galics 2.0 semi-analytic model of galaxy formation.

The Morphological Transformation and the Quenching of Galaxies [PDF]
The Astrophysical Journal, 2019 Abstract We study the morphological transformation from late types to early types and the quenching of galaxies with the seventh Data Release (DR7) of the Sloan Digital Sky Survey. Both early-type galaxies and late-type galaxies are found to have bimodal distributions on the star formation rate versus stellar mass diagram (lg SFR–lg M

Quenching of satellite galaxies at the outskirts of galaxy clusters [PDF]
Monthly Notices of the Royal Astronomical Society, 2018 We find, using cosmological simulations of galaxy clusters, that the hot X-ray emitting intra-cluster medium (ICM) enclosed within the outer accretion shock extends out to $R_{\rm shock}\sim(2 - 3) R_{\rm vir}$, where $R_{\rm vir}$ is the standard virial radius of the halo.

Investigating the Dominant Environmental Quenching Process in UVCANDELS/COSMOS Groups
The 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.

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

Bar quenching in gas-rich galaxies [PDF]
Astronomy & 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 ...

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