The Evolution of Environmental Quenching Timescales to $z\sim1.6$ [PDF]
, 2018 Using a sample of 4 galaxy clusters at $1.35 < z < 1.65$ and 10 galaxy clusters at $0.85 < z < 1.35$, we measure the environmental quenching timescale, $t_Q$, corresponding to the time required after a galaxy is accreted by a cluster for it to fully ...

Dissecting the Mass Quenching in TNG50: Galaxy Size Determines the Quenching Mode
The Astrophysical JournalThe diminishing of star formation is accompanied by size differentiating, as quiescent galaxies are more compact than star-forming galaxies (SFGs) at fixed stellar mass. In order to understand how galaxy quenching is related to galaxy sizes, we performed

From Clusters to Proto-Clusters: The Infrared Perspective on Environmental Galaxy Evolution
Universe, 2022 Environment is one of the primary drivers of galaxy evolution; via multiple mechanisms, it can control the critical process of transforming galaxies from star forming to quiescent, commonly termed “quenching”. Despite its importance, however, we still do

The Astrophysical Journal, 2023 We identify the intrinsic dependence of star formation quenching on a variety of galactic and environmental parameters, utilizing a machine-learning approach with Random Forest classification.

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.

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

Rapid Quenching of Galaxies at Cosmic Noon
The Astrophysical Journal, 2023 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 what physical mechanisms are involved.

Galaxy Quenching from Cosmic Web Detachment
The Open Journal of Astrophysics, 2019 We propose the Cosmic Web Detachment (CWD) model, a framework to interpret the star-formation history of galaxies in a cosmological context. The CWD model unifies several starvation mechanisms known to disrupt or stop star formation into one single ...

Pegasus W: An Ultrafaint Dwarf Galaxy Outside the Halo of M31 Not Quenched by Reionization
The Astrophysical Journal, 2023 We report the discovery of an ultrafaint dwarf (UFD) galaxy, Pegasus W, located on the far side of the Milky Way–M31 system and outside the virial radius of M31.
