Quenching time-scales of galaxies in the eagle simulations

Monthly Notices of the Royal Astronomical Society, 2019
We use the \eagle\ simulations to study the connection between the quenching timescale, $ _{\rm Q}$, and the physical mechanisms that transform star-forming galaxies into passive galaxies. By quantifying $ _{\rm Q}$ in two complementary ways - as the time over which (i) galaxies traverse the green valley on the colour-mass diagram, or (ii) leave the ...

Quenching of Massive Disk Galaxies in the IllustrisTNG Simulation

The Astrophysical Journal, 2022
Abstract A rare population of massive disk galaxies have been found to invade the red sequence dominated by early-type galaxies. The formation and origins of these red/quenched massive disk galaxies have recently gained great interest. The quenching mechanisms that are usually proposed, such as bar quenching and environment quenching, do

The UV properties of E+A galaxies: constraints on feedback-driven quenching of star formation [PDF]

, 2007
We present the first large-scale study of E+A (post-starburst) galaxies that incorporates photometry in the ultraviolet (UV) wavelengths. We find that the starburst that creates the E+A galaxy typically takes place within the last Gyr and creates a high ...

Revealing the Impact of Critical Stellar Central Density on Galaxy Quenching through Cosmic Time

The Astrophysical Journal
In a previous work, we investigated the structural and environmental dependence on quenching in the nearby universe. In this work, we extend our investigations to higher redshifts by combining galaxies from the Sloan Digital Sky Survey and The FourStar ...

ELUCID IV: Galaxy Quenching and its Relation to Halo Mass, Environment, and Assembly Bias

, 2017
We examine the quenched fraction of central and satellite galaxies as a function of galaxy stellar mass, halo mass, and the matter density of their large scale environment.

Galactic Archaeology with TESS: Prospects for Testing the Star Formation History in the Solar Neighbourhood [PDF]

, 2016
A period of quenching between the formation of the thick and thin disks of the Milky Way has been recently proposed to explain the observed age-[{\alpha}/Fe] distribution of stars in the solar neighbourhood.

The SAGA Survey. IV. The Star Formation Properties of 101 Satellite Systems around Milky Way–mass Galaxies

The Astrophysical Journal
We present the star-forming properties of 378 satellite galaxies around 101 Milky Way analogs in the Satellites Around Galactic Analogs (SAGA) Survey, focusing on the environmental processes that suppress or quench star formation.

Galaxy evolution in groups and clusters: satellite star formation histories and quenching timescales in a hierarchical Universe [PDF]

, 2012
Satellite galaxies in groups and clusters are more likely to have low star formation rates (SFR) and lie on the red-sequence than central (field) galaxies.

ELVES. III. Environmental Quenching by Milky Way–mass Hosts

The Astrophysical Journal, 2023
Isolated dwarf galaxies usually exhibit robust star formation but satellite dwarf galaxies are often devoid of young stars, even in Milky Way–mass groups.

Connecting Star Formation Quenching with Galaxy Structure and Supermassive Black Holes through Gravitational Heating of Cooling Flows

, 2014
Recent observations suggested that star formation quenching in galaxies is related to galaxy structure. Here we propose a new mechanism to explain the physical origin of this correlation. We assume that while quiescent galaxies are maintained quenched by
