Predicting Quiescence: The Dependence of Specific Star Formation Rate on
Galaxy Size and Central Density at 0.5
In this paper, we investigate the relationship between star formation and structure, using a mass-complete sample of 27,893 galaxies at $0 ...

Quenching of the star formation activity in cluster galaxies [PDF]
We study the star formation quenching mechanism in cluster galaxies by fitting the SED of the Herschel Reference Survey, a complete volume-limited K-band-selected sample of nearby galaxies including objects in different density regions, from the core of the Virgo cluster to the general field. The SED are fitted using the CIGALE SED modelling code.

The GOGREEN survey: transition galaxies and the evolution of environmental quenching [PDF]
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’ (

Galaxies in the act of quenching star formation [PDF]
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].

The imprint of cosmic web quenching on central galaxies
ABSTRACT We investigate how cosmic web environment impacts the average properties of central galaxies in the Sloan Digital Sky Survey (SDSS). We analyse how the average specific star formation rate, stellar age, metallicity, and element abundance ratio [α/Fe] of SDSS central galaxies depend on distance from the cosmic web nodes, walls ...

Evidence for strong evolution in galaxy environmental quenching efficiency between z = 1.6 and z = 0.9 [PDF]
Indexación: Web of Science; Scopus.We analyse the evolution of environmental quenching efficiency, the fraction of quenched cluster galaxies which would be star forming if they were in the field, as a function of redshift in 14 spectroscopically ...

Testing Galaxy Quenching Theories with Scatter in the Stellar to Halo Mass Relation [PDF]
We use the scatter in the stellar-to-halo mass relation to constrain galaxy evolution models. If the efficiency of converting accreted baryons into stars varies with time, halos of the same present-day mass but different formation histories will have ...

Evidence for a change in the dominant satellite galaxy quenching mechanism at z = 1. [PDF]
We present an analysis of galaxies in groups and clusters at 0.8 10(10.3) M-circle dot, we find f(convert) similar to 0.4 in the groups and similar to 0.6 in the clusters, similar to comparable measurements at z = 0.

There was a star-forming galaxy that was quenched
Cluster galaxies are subject to a whole range of processes and interactions that dramatically change their properties. To shed light on these issues, we analyze the most homogeneous and complete local cluster galaxy survey to date: WINGS/OmegaWINGS, and use stellar population synthesis techniques to obtain properties such as stellar mass, stellar ages,
