Both starvation and outflows drive galaxy quenching [PDF]

Monthly Notices of the Royal Astronomical Society, 2019
ABSTRACT Star-forming galaxies can in principle be transformed into passive systems by a multitude of processes that quench star formation, such as the halting of gas accretion (starvation) or the rapid removal of gas in AGN-driven outflows.

The Suppression of Star Formation and the Effect of Galaxy Environment in Low-Redshift Galaxy Groups

, 2012
Understanding the interaction between galaxies and their surroundings is central to building a coherent picture of galaxy evolution. Here we use GALEX imaging of a statistically representative sample of 23 galaxy groups at z=0.06 to explore how local and

Environmental quenching of low-mass field galaxies [PDF]

Monthly Notices of the Royal Astronomical Society, 2018
In the local Universe, there is a strong division in the star-forming properties of low-mass galaxies, with star formation largely ubiquitous amongst the field population while satellite systems are predominantly quenched. This dichotomy implies that environmental processes play the dominant role in suppressing star formation within this low-mass ...

TwO Parameters Semi Empirical Model (TOPSEM): Galaxy Evolution and Bulge/Disk Dicothomy from Two-stage Halo Accretion

The Astrophysical Journal, 2023
In recent years, increasing attention has been devoted to semi-empirical, data-driven models to tackle some aspects of the complex and still largely debated topic of galaxy formation and evolution. We here present a new semi-empirical model whose marking

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.

Galaxy And Mass Assembly (GAMA) : The mechanisms for quiescent galaxy formation at z<1 [PDF]

, 2017
© 2016 The Authors. One key problem in astrophysics is understanding how and why galaxies switch off their star formation, building the quiescent population that we observe in the local Universe.

Photometric Objects Around Cosmic Webs (PAC). VII. Disentangling Mass and Environment Quenching with the Aid of Galaxy–Halo Connection in Simulations

The Astrophysical Journal
Star formation quenching in galaxies plays a crucial role in galaxy evolution and is believed to be driven primarily by galaxy mass and environment.

Effect of local environment and stellar mass on galaxy quenching and morphology at $0.5

, 2017
We study galactic star-formation activity as a function of environment and stellar mass over 0.5 0.5 it depends on galaxy stellar mass, demonstrating that the effects of quenching related to (stellar) mass and environment are not separable.

Evidence of Environmental Quenching at Redshift z ~ 2 [PDF]

, 2018
We report evidence of environmental quenching among galaxies at redshift ~ 2, namely the probability that a galaxy quenches its star formation activity is enhanced in the regions of space in proximity of other quenched, more massive galaxies.
