On the Origin of Quenched but Gas-rich Regions at Kiloparsec Scales in Nearby Galaxies

The Astrophysical Journal
We 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.

Spider-webb: Spatially Resolved Evidence of Inside-out Quenching in the Spiderweb Protocluster at z ∼ 2

The Astrophysical Journal
We present a spatially resolved analysis of galaxy quenching within the Spiderweb Protocluster at z  ∼ 2.16, combining deep imaging from the James Webb Space Telescope (JWST) and the Hubble Space Telescope.

Hedgehog: An Isolated Quiescent Dwarf Galaxy at 2.4 Mpc

The Astrophysical Journal Letters
It 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 Dependence of Dark Matter Halo Properties on the Morphology of Their Central Galaxies from Weak Lensing

The Astrophysical Journal
Xu & Jing reported a monotonic relationship between the host halo mass M _h and the morphology of massive central galaxies, characterized by the Sérsic index n , at fixed stellar mass, suggesting that morphology could serve as a good secondary proxy for ...

Quenching of galaxies at cosmic noon

Astronomy & Astrophysics
Context. We identified and analysed massive quiescent galaxies (MQGs) at z ≈ 3.1 within the 2 deg2 COSMOS field and explored the effect of the galaxy environment on quenching processes. By examining the variation in the quenched fraction and physical properties of these galaxies in different environmental contexts, including local densities ...

The Importance of Gas Starvation in Driving Satellite Quenching in Galaxy Groups at z ~ 0.8

The Astrophysical Journal
We 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

The SAGA Survey. VI. The Size–Mass Relation for Low-mass Galaxies Across Environments

The Astrophysical Journal
We investigate how Milky Way (MW)–like environments influence the sizes and structural properties of low-mass galaxies by comparing satellites of MW analogs from the Satellites Around Galactic Analogs (SAGA) Survey with two control samples: an ...

DESI Massive Poststarburst Galaxies at z ∼ 1.2 Have Compact Structures and Dense Cores

The Astrophysical Journal
Poststarburst 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.

Two Distinct Classes of Quiescent Galaxies at Cosmic Noon Revealed by JWST PRIMER and UNCOVER

The Astrophysical Journal Letters
We present a measurement of the low-mass quiescent size–mass relation at cosmic noon (1 < z < 3) from the JWST PRIMER and UNCOVER treasury surveys, which highlights two distinct classes of quiescent galaxies.
