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 $Λ$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

Investigating the Dominant Environmental Quenching Process in UVCANDELS/COSMOS Groups

The Astrophysical Journal, 2023
We explore how the fraction of quenched galaxies changes in groups of galaxies with respect to the distance to the center of the group, redshift, and stellar mass to determine the dominant process of environmental quenching in 0.2 < z < 0.8 groups.

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 &lt; z &lt; 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 ...

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 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 ...

The size evolution of star-forming and quenched galaxies in the IllustrisTNG simulation

, 2018
We analyse scaling relations and evolution histories of galaxy sizes in TNG100, part of the IllustrisTNG simulation suite. Observational qualitative trends of size with stellar mass, star formation rate and redshift are reproduced, and a quantitative ...
