A STELLAR MASS THRESHOLD FOR QUENCHING OF FIELD GALAXIES [PDF]
The Astrophysical Journal, 2012 We demonstrate that dwarf galaxies (10^7 < M_stellar < 10^9 Msun) with no active star formation are extremely rare (<0.06%) in the field. Our sample is based on the NASA-Sloan Atlas which is a re-analysis of the Sloan Digital Sky Survey Data Release 8.

Death at watersheds: Galaxy quenching in low-density environments [PDF]
Astronomy & Astrophysics, 2022 Our aim is to understand the effect of environment to galaxy quenching in various local and global environments. We focus on galaxies with very old stellar populations (VO galaxies), typically found in the centers of clusters and groups, and search for ...

Signatures of quenching in dwarf galaxies in local galaxy clusters [PDF]
Astronomy & Astrophysics, 2021 Context. The transformation of late-type galaxies has been suggested as the origin of early-type dwarf galaxies (typically M⋆ ≤ 109 M⊙) in galaxy clusters. Based on deep images, Venhola and colleagues analysed correlations between colour and surface brightness for galaxies in the Fornax cluster binned by luminosity or stellar mass. In the bins with M⋆ &

The role of stochastic and smooth processes in regulating galaxy quenching [PDF]
Astronomy & Astrophysics, 2021 Context. Galaxies can be classified as passive ellipticals or star-forming discs. Ellipticals dominate at the high end of the mass range, and therefore there must be a mechanism responsible for the quenching of star-forming galaxies. This could either be

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

What drives galaxy quenching? Resolving molecular gas and star formation in the green valley [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2020 We study quenching in seven green valley galaxies on kpc scales by resolving their molecular gas content using 12CO(1–0) observations obtained with NOrthern Extended Millimeter Array and Atacama Large Millimeter Array, and their star formation rate ...

THE QUENCHING TIMESCALE AND QUENCHING RATE OF GALAXIES [PDF]
The Astrophysical Journal, 2016 ABSTRACT The average star formation rate (SFR) in galaxies has been declining since the redshift of 2. A fraction of galaxies quench and become quiescent. We constrain two key properties of the quenching process: the quenching timescale and the quenching rate among galaxies.
