The First Quenched Galaxies: When and How? [PDF]

open access: yesThe Astrophysical Journal Letters
Many 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 ...

DESI Survey Validation Spectra Reveal an Increasing Fraction of Recently Quenched Galaxies at z ∼ 1 [PDF]

open access: yesThe 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

Euclid Quick Data Release (Q1) [PDF]

open access: yesAstronomy & Astrophysics
Investigating what drives the quenching of star formation in galaxies is key to understanding their evolution. The Euclid mission will provide rich spatial and spectral data from optical to infrared wavelengths for millions of galaxies, and enable ...

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

open access: yesThe 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

Systematically Measuring Ultradiffuse Galaxies. IX. A Gigayear in the Life of Nearby Low-surface-brightness Galaxies

open access: yesThe Astrophysical Journal
We augment the published optical photometry of ultradiffuse galaxy candidates in the SMUDGes catalog with UV and IR measurements to investigate the recent (

Quenching of Massive Disk Galaxies in the IllustrisTNG Simulation

open access: yesThe 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.

Rejuvenating & Quenching: Gas Properties of Transitional Galaxies [PDF]

open access: yes, 2023
Most galaxies are either actively forming stars or quenched, but there is a small number of galaxies in transition from one population to the other. These galaxies are "quenching" if they are in the process of becoming quenched or "rejuvenating" if they ...

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

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

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

open access: yesThe 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).
