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.

There was a star-forming galaxy that was quenched
, 2022 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,

The Roles of Mass and Environment in the Quenching of Galaxies. II. [PDF]
The Astrophysical Journal, 2020 Abstract We take advantage of an analytic model of galaxy formation coupled to the merger tree of an N-body simulation to study the roles of environment and stellar mass in the quenching of galaxies. The model has been originally set in order to provide the observed evolution of the stellar mass function as well as reasonable predictions

The imprint of cosmic web quenching on central galaxies
Monthly Notices of the Royal Astronomical Society, 2021 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 ...

A STELLAR MASS THRESHOLD FOR QUENCHING OF FIELD GALAXIES [PDF]
The Astrophysical Journal, 2012 We demonstrate that dwarf galaxies (10^7 < M_stellar < 10^9 Msun) with no active star formation are extremely rare (<0.06%) in the field. Our sample is based on the NASA-Sloan Atlas which is a re-analysis of the Sloan Digital Sky Survey Data Release 8.

The impact of quenching on galaxy profiles in the
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT We study specific star formation rate (sSFR) and gas profiles of star-forming (SF) and green valley (GV) galaxies in the simba cosmological hydrodynamic simulation. SF galaxy half-light radii (Rhalf) at z = 0 and their evolution (∝(1 + z)−0.78) agree with observations.
