The Colors and Sizes of Recently Quenched Galaxies: A Result of Compact Starburst before Quenching [PDF]

The Astrophysical Journal, 2020
Abstract We analyze the colors and sizes of 32 quiescent (UVJ-selected) galaxies with strong Balmer absorption (EW(Hδ) ≥ 4 Å) at z ∼ 0.8 drawn from DR2 of the LEGA-C survey to test the hypothesis that these galaxies experienced compact, central starbursts before quenching.

Identifying and Distinguishing Quenching Galaxies with Spatially Resolved Star Formation in TNG50 [PDF]

The Astrophysical Journal
Using the TNG50 simulation, we determine observationally motivated metrics that can distinguish quenching galaxies from star-forming galaxies for M _* ≥ 10 ^9.5 M _⊙ , based on the spatial distribution of their stellar populations. Quenching galaxies are

Discrepancies between JWST Observations and Simulations of Quenched Massive Galaxies at z > 3: A Comparative Study with IllustrisTNG and ASTRID

The Astrophysical Journal
Recent JWST observations have uncovered an unexpectedly large population of massive quiescent galaxies at z  > 3. Using the cosmological simulations IllustrisTNG and ASTRID , we identify analogous galaxies and investigate their abundance, formation ...

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.

An Unexpected Population of Quenched Galaxies Harboring Undermassive SMBHs Revealed by Tidal Disruption Events [PDF]

The Astrophysical Journal Letters
Restricted by event horizon suppression, tidal disruption events (TDEs) provide a unique window into otherwise hidden supermassive black holes (SMBHs) at the lower end of the mass spectrum, allowing the connection between star formation and SMBH mass to ...

The connection between dusty star-forming galaxies and the first massive quenched galaxies

Astronomy & Astrophysics
High-redshift (z ≳ 2) massive quiescent galaxies (MQs) provide an opportunity to probe the key physical processes driving the fuelling and quenching of star formation in the early Universe.

GASP XXIV. The History of Abruptly Quenched Galaxies in Clusters [PDF]

, 2020
The study of cluster post-starburst galaxies gives useful insights on the physical processes quenching the star formation in the most massive environments.

Galaxy Zoo: Major Galaxy Mergers Are Not a Significant Quenching Pathway* [PDF]

The Astrophysical Journal, 2017
Abstract 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.

Beyond Ultra-diffuse Galaxies. II. Environmental Quenching of Mass–Size Outliers among the Satellites of Milky Way Analogs

The Astrophysical Journal, 2023
Recent observations have reignited interest in a population of dwarf galaxies that are large and diffuse for their mass, often called ultra-diffuse galaxies (UDGs).
