The First Quenched Galaxies: When and How?

The 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 ...

Rapid Quenching of Galaxies at Cosmic Noon [PDF]

The Astrophysical Journal, 2023
The existence of massive quiescent galaxies at high redshift seems to require rapid quenching, but it is unclear whether all quiescent galaxies have gone through this phase and what physical mechanisms are involved.

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

The 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

Relight the Candle: What Happens to High-redshift Massive Quenched Galaxies

The Astrophysical Journal, 2023
A puzzling population of extremely massive quiescent galaxies at redshifts beyond z = 3 has recently been revealed by JWST and the Atacama Large Millimeter/submillimeter Array, some of them with stellar ages that show their quenching times to be as high ...

Blowing Out the Candle: How to Quench Galaxies at High Redshift—An Ensemble of Rapid Starbursts, AGN Feedback, and Environment [PDF]

The Astrophysical Journal, 2023
Recent observations with JWST and the Atacama Large Millimeter/submillimeter Array have revealed extremely massive quiescent galaxies at redshifts of z = 3 and higher, indicating both rapid onset and quenching of star formation.

JADES + JEMS: A Detailed Look at the Buildup of Central Stellar Cores and Suppression of Star Formation in Galaxies at Redshifts 3 < z < 4.5 [PDF]

The Astrophysical Journal, 2023
We present a spatially resolved study of stellar populations in six galaxies with stellar masses M _* ∼ 10 ^10 M _☉ at z ∼ 3.7 using 14-filter James Webb Space Telescope (JWST)/NIRCam imaging from the JADES and JEMS surveys. The six galaxies are visually

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 ...

Recovering the Star Formation Histories of Recently Quenched Galaxies: The Impact of Model and Prior Choices [PDF]

Astrophysical Journal, 2022
Accurate models of the star formation histories (SFHs) of recently quenched galaxies can provide constraints on when and how galaxies shut down their star formation.

Merger Signatures are Common, but not Universal, in Massive, Recently Quenched Galaxies at z ∼ 0.7 [PDF]

Astrophysical Journal, 2022
We present visual classifications of merger-induced tidal disturbances in 143 M * ∼ 1011 M ⊙ post-starburst galaxies at z ∼ 0.7 identified in the SQuIGGL⃗E Sample. This sample spectroscopically selects galaxies from the Sloan Digital Sky Survey that have
