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 ...

Catching galaxies in the act of quenching star formation [PDF]
Monthly Notices of the Royal Astronomical Society, 2018 Detecting galaxies when their star-formation is being quenched is crucial to understand the mechanisms driving their evolution. We identify for the first time a sample of quenching galaxies selected just after the interruption of their star formation by exploiting the [O III]5007/Halpha ratio and searching for galaxies with undetected [O III].

Galaxy Quenching with Mass Growth History of Galaxy Groups and Clusters: The Importance of Post-processing [PDF]
The Astrophysical Journal, 2023 We investigate the fraction of quenched satellite galaxies in host galaxy groups and clusters using TNG300 in the IllustrisTNG cosmological magnetohydrodynamical simulations.

The quenching time scale and quenching rate of galaxies [PDF]
The Astrophysical Journal, 2016 The average star formation rate (SFR) in galaxies has been declining since redshift of 2. A fraction of galaxies quench and become quiescent. We constrain two key properties of the quenching process: the quenching time scale and the quenching rate among galaxies.

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.

Star Formation Quenching Timescale of Central Galaxies in a Hierarchical Universe [PDF]
, 2016 Central galaxies make up the majority of the galaxy population, including the majority of the quiescent population at $\mathcal{M}_* > 10^{10}\mathrm{M}_\odot$. Thus, the mechanism(s) responsible for quenching central galaxies plays a crucial role in galaxy evolution as whole.

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.

Galaxy Zoo: major galaxy mergers are not a significant quenching pathway [PDF]
The Astrophysical Journal, 2017 We use stellar mass functions to study the properties and the significance of quenching through major galaxy mergers. In addition to SDSS DR7 and Galaxy Zoo 1 data, we use samples of visually selected major galaxy mergers and post merger galaxies. We determine the stellar mass functions of the stages that we would expect major merger quenched galaxies ...

Merger Shocks Enhance Quenching in Local Galaxy Clusters [PDF]
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.

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.
