The State of the Molecular Gas in Post-starburst Galaxies
The molecular gas in galaxies traces both the fuel for star formation and the processes that can enhance or suppress star formation. Observations of the molecular gas state can thus point to when and why galaxies stop forming stars.

An Explanation for the Overrepresentation of Tidal Disruption Events in Post-starburst Galaxies
Tidal disruption events (TDEs) provide a valuable probe for studying the dynamics of stars in the nuclear environments of galaxies. Recent observations show that TDEs are strongly overrepresented in post-starburst or “green valley” galaxies, although the

Stars, Gas, and Star Formation of Distant Post-starburst Galaxies
We present a comprehensive multiwavelength study of five post-starburst galaxies with M _* > 10 ^11 M _⊙ at z ∼ 0.7, examining their stars, gas, and current and past star formation activities.

Merger Signatures are Common, but not Universal, in Massive, Recently Quenched Galaxies at z ∼ 0.7
We present visual classifications of merger-induced tidal disturbances in 143 M _* ∼ 10 ^11 M _⊙ post-starburst galaxies at z ∼ 0.7 identified in the $\mathrm{SQuIGG}\vec{L}{\rm{E}}$ Sample.

An Extremely Compact, Low-mass Galaxy on its Way to Quiescence at z = 5.2
We report the discovery of a low-mass z = 5.200 ± 0.002 galaxy that is in the process of ceasing its star formation. The galaxy, MACS0417-z5BBG, is multiply imaged with magnification factors ∼40 by the galaxy cluster MACS J0417.5-1154, observed as part ...

2022 report from the Auger-TA working group on UHECR arrival directions [PDF]
After over 60 years, the powerful engines that accelerate ultra-high-energy cosmic rays (UHECRs) to the formidable energies at which we observe them from Earth remain mysterious.

Two main physical processes characterize the activity in the nuclear region of active galaxies: an intense star formation (starburst, SB) and an Active Galactic Nucleus (AGN).

Cosmic Sands: The Origin of Dusty, Star-forming Galaxies in the Epoch of Reionization
We present the Cosmic Sands suite of cosmological zoom-in simulations based on the simba galaxy formation model in order to study the buildup of the first massive and dusty galaxies in the early universe.

Sparks: The Magellan/FIRE Survey from Starburst to Post-starburst
Rapid transitions from starburst to quiescence constitute a key evolutionary pathway in galaxy formation. Post-starburst galaxies trace this brief phase, exhibiting optical spectra dominated by intermediate-age stellar populations with strong Balmer ...

Equivalent widths of spectral lines in the optical spectra of galaxies are commonly used to characterize their stellar populations and to get some insight on their evolution.
