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 ...

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 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.

Bursting and quenching in satellite galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2019 ABSTRACT The difference in stellar metallicity between red and blue galaxies with the same mass constrains the time-scale over which red galaxies ceased to form stars. Here we investigate this constraint with the galics 2.0 semi-analytic model of galaxy 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.

The environmental dependence of rapidly quenching and rejuvenating galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT By combining H α flux measurements from the Sloan Digital Sky Survey (SDSS) with ultraviolet (UV) flux observations from the Galaxy Evolution Explorer (GALEX), we examine the environmental dependence (through central/satellite distinction) of the rapid quenching and rejuvenation of galaxies.

The Astrophysical Journal, 2023 Conformity denotes the correlation of properties between pairs of galaxies as a function of separation. Correlations between properties such as the star formation rate (SFR), stellar mass, and specific star formation rate (sSFR) have implications for the
