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.

Environmental quenching of low-mass field galaxies. [PDF]
Mon Not R Astron Soc, 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 ...

Satellite dwarf galaxies: stripped but not quenched [PDF]
Astronomy and Astrophysics, 2019 In the Local Group, quenched gas-poor dwarfs galaxies are most often found close to the Milky Way and Andromeda, while star forming gas-rich ones are located at greater distances. This so-called morphology-density relation is often interpreted as the consequence of the ram pressure stripping of the satellites during their interaction with the Milky Way

The First Quenched Galaxies: When and How?
The Astrophysical Journal LettersMany quiescent galaxies discovered in the early Universe by JWST raise fundamental questions on when and how these galaxies became and stayed quenched. Making use of the latest version of the semianalytic model GAEA that provides good agreement with the ...

Quenched Galaxies in Clusters of Galaxies and Their Outskirts [PDF]
Astrophysical Bulletin, 2020 Based on the SDSS data, the properties of galaxies with quenched star formation (QGs) within the "splashback"-radius of galaxy clusters $R_{\rm sp}$ and beyond it have been studied.

Quenching of satellite galaxies at the outskirts of galaxy clusters [PDF]
Monthly Notices of the Royal Astronomical Society, 2018 We find, using cosmological simulations of galaxy clusters, that the hot X-ray emitting intra-cluster medium (ICM) enclosed within the outer accretion shock extends out to $R_{\rm shock}\sim(2 - 3) R_{\rm vir}$, where $R_{\rm vir}$ is the standard virial radius of the halo.

The Morphological Transformation and the Quenching of Galaxies [PDF]
The Astrophysical Journal, 2019 Abstract We study the morphological transformation from late types to early types and the quenching of galaxies with the seventh Data Release (DR7) of the Sloan Digital Sky Survey. Both early-type galaxies and late-type galaxies are found to have bimodal distributions on the star formation rate versus stellar mass diagram (lg SFR–lg M

Quenching of Massive Disk Galaxies in the IllustrisTNG Simulation
The Astrophysical Journal, 2022 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.

DESI Survey Validation Spectra Reveal an Increasing Fraction of Recently Quenched Galaxies at z ∼ 1
The Astrophysical Journal Letters, 2023 We utilize ∼17,000 bright luminous red galaxies (LRGs) from the novel Dark Energy Spectroscopic Instrument Survey Validation spectroscopic sample, leveraging its deep (∼2.5 hr galaxy ^−1 exposure time) spectra to characterize the contribution of recently
