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 [PDF]
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 ...

Probing Satellite Quenching With Galaxy Clustering [PDF]
Monthly Notices of the Royal Astronomical Society, 2014 Satellites within simulated massive clusters are significantly spatially correlated with each other, even when those satellites are not gravitationally bound to each other.

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

The First Quenched Galaxies: When and How?
The Astrophysical Journal LettersMany quiescent galaxies discovered in the early Universe by JWST raise fundamental questions on when and how these galaxies became and stayed quenched. Making use of the latest version of the semianalytic model GAEA that provides good agreement with the ...

Merger Shocks Enhance Quenching in Local Galaxy Clusters
The Astrophysical JournalWe report evidence for enhanced quenching in low-redshift galaxy clusters hosting radio relics. This effect is strongest for low-mass galaxies and is consistent with a rapid quenching of star formation.

Galaxy zoo: stronger bars facilitate quenching in star-forming galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 ABSTRACTWe have used Galaxy Zoo DECaLS (GZD) to study strong and weak bars in disc galaxies. Out of the 314 000 galaxies in GZD, we created a volume-limited sample (0.01 < z < 0.05, Mr < − 18.96) which contains 1867 galaxies with reliable volunteer bar classifications in the ALFALFA footprint.

Quenched Galaxies in Clusters of Galaxies and Their Outskirts [PDF]
Astrophysical Bulletin, 2020 Based on the SDSS data, the properties of galaxies with quenched star formation (QGs) within the "splashback"-radius of galaxy clusters $R_{\rm sp}$ and beyond it have been studied.

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

Quenching star formation in cluster galaxies [PDF]
Monthly 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.
