Galaxy Zoo: Major Galaxy Mergers Are Not a Significant Quenching Pathway* [PDF]
The Astrophysical Journal, 2017 Abstract 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.

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.

Overconsumption, outflows and the quenching of satellite galaxies [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2014 Abstract The baryon cycle of galaxies is a dynamic process involving the intake, consumption and ejection of vast quantities of gas. In contrast, the conventional picture of satellite galaxies has them methodically turning a large gas reservoir into stars until this reservoir is forcibly removed due to external ram pressure. This picture

What drives galaxy quenching? A deep connection between galaxy kinematics and quenching in the local Universe [PDF]
Monthly Notices of the Royal Astronomical Society, 2022 ABSTRACT We develop a 2D inclined rotating disc model, which we apply to the stellar velocity maps of 1862 galaxies taken from the MaNGA survey (SDSS public Data Release 15) . We use a random forest classifier to identify the kinematic parameters that are most connected to galaxy quenching.

The GOGREEN survey: transition galaxies and the evolution of environmental quenching [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 ABSTRACT We measure the rate of environmentally driven star formation quenching in galaxies at z ∼ 1, using eleven massive ($M\approx 2\times 10^{14}\, \mathrm{M}_\odot$) galaxy clusters spanning a redshift range 1.0 < z < 1.4 from the GOGREEN sample. We identify three different types of transition galaxies: ‘green valley’ (

Probing satellite quenching with galaxy clustering [PDF]
Monthly Notices of the Royal Astronomical Society, 2015 Satellites within simulated massive clusters are significantly spatially correlated with each other, even when those satellites are not gravitationally bound to each other. This correlation is produced by satellites that entered their hosts relatively recently, and is undetectable for satellites that have resided in their hosts for multiple dynamical ...

THE QUENCHING TIMESCALE AND QUENCHING RATE OF GALAXIES
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.

The Way to Quench: Galaxy Evolution in A2142
Research in Astronomy and Astrophysics, 2023 Abstract We show how the star formation activity of galaxies is progressively inhibited from the outer region to the center of the massive cluster A2142. From an extended spectroscopic redshift survey of 2239 galaxies covering a circular area of radius ∼11 Mpc from the cluster center, we extract a sample of 333 galaxies with known ...

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.
