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.

The Role of Galaxy Clusters in Shaping the Size Growth and Quenching of Galaxies

, 2021
The cluster environment is known to be capable of altering the evolutionary paths of galaxies through a variety of mechanisms. High relative velocities of satellite galaxies make minor mergers between them rare. The presence of an intra-cluster medium makes it possible to rapidly quench star formation in satellite galaxies via gas stripping processes ...

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 ...

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.

Testing Galaxy Formation Models with the Stellar Mass–Halo Mass Relations for Star-forming and Quiescent Galaxies

The Astrophysical Journal
The tight relationship between the stellar mass and halo mass of galaxies is one of the most fundamental scaling relations in galaxy formation and evolution. It has become a critical constraint for galaxy formation models.

Active Galactic Nuclei in the Green Valley at z ∼ 0.7

The Astrophysical Journal
We present near-infrared (NIR) spectroscopy using the MMT and Magellan infrared spectrograph for a sample of 29 massive galaxies ( $\mathrm{log}\ {M}_{* }/{M}_{\odot }\gtrsim 10$ ) at z ∼ 0.7 with optical spectroscopy from the Large Early Galaxy ...

Improved SED-fitting Assumptions Result in Inside-out Quenching at z ~ 0.5 and Quenching at All Radii Simultaneously at z ~ 1

The Astrophysical Journal
Many studies conclude that galaxies quench from the inside-out by examining profiles of specific star formation rate (sSFR). These are usually measured by fitting spectral energy distributions (SEDs) assuming a fixed dust law and uniform priors on all ...
