The Morphological Transformation and the Quenching of Galaxies [PDF]
The Astrophysical Journal, 2019 Abstract We study the morphological transformation from late types to early types and the quenching of galaxies with the seventh Data Release (DR7) of the Sloan Digital Sky Survey. Both early-type galaxies and late-type galaxies are found to have bimodal distributions on the star formation rate versus stellar mass diagram (lg SFR–lg M

The SAMI Galaxy Survey: Observing the environmental quenching of star formation in GAMA groups [PDF]
, 2019 We explore the radial distribution of star formation in galaxies in the SAMI Galaxy Survey as a function of their Local Group environment. Using a sample of galaxies in groups (with halo masses less than ≃ 1014M⊙) from the Galaxy And Mass Assembly Survey,

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

The role of stochastic and smooth processes in regulating galaxy quenching [PDF]
, 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

Satellite dwarf galaxies: stripped but not quenched [PDF]
Astronomy & Astrophysics, 2019 In the Local Group, quenched gas-poor dwarfs galaxies are most often found close to the Milky Way and Andromeda, while star forming gas-rich ones are located at greater distances. This so-called morphology-density relation is often interpreted as the consequence of the ram pressure stripping of the satellites during their interaction with the Milky Way

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 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 ...
