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.

SQuIGG E: Observational Evidence of Low Ongoing Star Formation Rates in Gas-rich Post-starburst Galaxies

The Astrophysical Journal
Atacama Large Millimeter/submillimeter Array observations have shown that candidate “post-starburst” galaxies (PSBs) at z  ∼ 0.6 can retain significant molecular gas reservoirs.

The Delay Time Distribution of Quasiperiodic Eruptions

The Astrophysical Journal Letters
Quasiperiodic eruptions (QPEs) are quasiperiodic X-ray bursts observed in the nucleus of a galaxy. Multiple pieces of observational evidence link QPEs to tidal disruption events (TDEs), which occur when stars are disrupted after approaching a ...

Decoding the Single-peaked H i Spectra of Low Redshift Poststarburst Galaxies

The Astrophysical Journal
Recent observations with the Five-hundred-meter Aperture Spherical Telescope have revealed abundant reservoirs of neutral hydrogen (H I ) in low-redshift poststarburst galaxies (PSBs), raising the question of why star formation ceases rapidly in these ...

Astronomy & Astrophysics
Context. Galaxies may suffer some starburst and quenched periods in their history due to galaxy mergers and feedback. However, semi-numerical simulations of the Epoch of Reionization (EoR) do not accurately model the effects of the star formation history

Population Models for Star Formation Timescales in Early Galaxies: The First Step toward Solving Outshining in Star Formation History Inference

The Astrophysical Journal
James Webb Space Telescope (JWST) has revealed temporarily quenched and ultraviolet-luminous galaxies in the early Universe, suggesting enhanced star formation stochasticity. Verifying this hypothesis is critical yet challenging.

Quiescent Host Galaxies of Extended Quasars Revealed by Spectrophotometric Decomposition

The Astrophysical Journal
Previous works of low-redshift quasar host galaxies have focused on compact quasars and found that their host galaxies are mainly star-forming galaxies.
