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.

A dichotomy in satellite quenching around L* galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2013 We examine the star formation properties of bright (~0.1 L*) satellites around isolated ~L* hosts in the local Universe using spectroscopically confirmed systems in the Sloan Digital Sky Survey DR7. Our selection method is carefully designed with the aid of N-body simulations to avoid groups and clusters.

The Astrophysical JournalThe formation pathways of lenticular galaxies (S0s) in field environments remain a matter of debate. We utilize the cosmological hydrodynamic simulation, NewHorizon , to investigate the issue. We select two massive star formation quenched S0s as our main

The Astrophysical JournalEnvironment plays a critical role in shaping the assembly of low-mass galaxies. Here, we use the U niverse M achine (UM) galaxy–halo connection framework and Data Release 3 of the Satellites Around Galactic Analogs (SAGA) Survey to place dwarf galaxy ...

On the Origin of Quenched but Gas-rich Regions at Kiloparsec Scales in Nearby Galaxies
The Astrophysical JournalWe use resolved spectroscopy from MaNGA to investigate the significance of both local and global properties of galaxies to the cessation of star formation at kpc scales.

Hedgehog: An Isolated Quiescent Dwarf Galaxy at 2.4 Mpc
The Astrophysical Journal LettersIt is well known that almost all isolated dwarf galaxies are actively forming stars. We report the discovery of dw1322m2053 (nicknamed Hedgehog), an isolated quiescent dwarf galaxy at a distance of 2.40 ± 0.15 Mpc with a stellar mass of M _⋆ ≈ 10 ^5.8 M ...

The Importance of Gas Starvation in Driving Satellite Quenching in Galaxy Groups at z ~ 0.8
The Astrophysical JournalWe present results from a Keck/DEIMOS survey to study satellite quenching in group environments at z ~ 0.8 within the Extended Groth Strip (EGS). We target 11 groups in the EGS with extended X-ray emission. We obtain high-quality spectroscopic redshifts

DESI Massive Poststarburst Galaxies at z ∼ 1.2 Have Compact Structures and Dense Cores
The Astrophysical JournalPoststarburst galaxies (PSBs) are young quiescent galaxies that have recently experienced a rapid decrease in star formation, allowing us to probe the fast-quenching period of galaxy evolution.
