THE MASS DEPENDENCE OF DWARF SATELLITE GALAXY QUENCHING [PDF]
The Astrophysical Journal, 2014 We combine observations of the Local Group with data from the NASA-Sloan Atlas to show the variation in the quenched fraction of satellite galaxies from low-mass dwarf spheroidals and dwarf irregulars to more massive dwarfs similar to the Magellanic ...

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.

Galaxy Zoo: Major Galaxy Mergers Are Not a Significant Quenching Pathway* [PDF]
The Astrophysical Journal, 2017 We use stellar mass functions to study the properties and the significance of quenching through major galaxy mergers. In addition to SDSS DR7 and Galaxy Zoo 1 data, we use samples of visually selected major galaxy mergers and post merger galaxies. We determine the stellar mass functions of the stages that we would expect major merger quenched galaxies ...

The quenching time scale and quenching rate of galaxies [PDF]
The Astrophysical Journal, 2016 The average star formation rate (SFR) in galaxies has been declining since redshift of 2. A fraction of galaxies quench and become quiescent. We constrain two key properties of the quenching process: the quenching time scale and the quenching rate among galaxies.

Estimation of the Galaxy Quenching Rate in the Illustris Simulation [PDF]
, 2020 Quenching is a key topic in exploring the formation and evolution of galaxies. In this work, we study the quenching rate, i.e., the variation in the fraction of quenched galaxies per unit time, of the Illustris-1 simulation.

Rapid Quenching of Galaxies at Cosmic Noon
The Astrophysical Journal, 2023 The existence of massive quiescent galaxies at high redshift seems to require rapid quenching, but it is unclear whether all quiescent galaxies have gone through this phase and what physical mechanisms are involved.

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 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).

Galaxy Quenching with Mass Growth History of Galaxy Groups and Clusters: The Importance of Post-processing [PDF]
The Astrophysical Journal, 2023 We investigate the fraction of quenched satellite galaxies in host galaxy groups and clusters using TNG300 in the IllustrisTNG cosmological magnetohydrodynamical simulations.

Filaments in VIPERS: galaxy quenching in the infalling regions of groups [PDF]
Monthly Notices of the Royal Astronomical Society, Volume 484,
Issue 1, 21 March 2019, Pages 2-7, 2019 We study the quenching of galaxies in different environments and its evolution in the redshift range $0.43 \leq z \leq 0.89$. For this purpose, we identify galaxies inhabiting filaments, the isotropic infall region of groups, the field, and groups in the

Quenching of Massive Disk Galaxies in the IllustrisTNG Simulation [PDF]
The Astrophysical Journal, 2022 A rare population of massive disk galaxies have been found to invade the red sequence dominated by early-type galaxies. These red/quenched massive disk galaxies have recently gained great interest into their formation and origins. The usually proposed quenching mechanisms, such as bar quenching and environment quenching, seem not suitable for those ...
