SQuIGGE: Spatially resolved NIRSpec Pa reveals that the most CO-luminous, post-starburst galaxies exhibit falling---but still active---star formation behind optically thick dust
David J. Setton, Jenny E. Greene, Rachel Bezanson +13
One of the fundamental uncertainties in the study of galaxies at the interface between star formation and quiescence--post-starburst galaxies--is their instantaneous star formation…

Water absorption confirms cool atmospheres in two little red dots
Bingjie Wang, Joel Leja, Ivo Labbe +35
Little red dots (LRDs) are an abundant population of compact high-redshift sources with red rest-frame optical continua, discovered by the James Webb Space Telescope (JWST). Their…
Molecular Gas Excitation in z ~ 0.7 Gas-Rich Post-starburst Galaxies from SQuIGGLE
Vincenzo R. D'Onofrio, Justin S. Spilker, Rachel Bezanson +10
Many post-starburst galaxies at have been shown to retain substantial molecular gas reservoirs yet host low ongoing star formation, suggesting that the remaining gas may…
The X-Ray Dot: Exotic Dust or a Late-Stage Little Red Dot?
Raphael E. Hviding, Anna de Graaff, Hanpu Liu +15
JWST's "Little Red Dots" (LRDs) are increasingly interpreted as active galactic nuclei (AGN) obscured by dense thermalized gas rather than dust as evidenced by their X-ray weakness…
Little Red Dot Host Galaxy Black Hole Star: A Gas-Enshrouded Heart at the Center of Every Little Red Dot
Wendy Q. Sun, Rohan P. Naidu, Jorryt Matthee +30
The central engines of Little Red Dots (LRDs) may be ``black hole stars" (BH*s), early stages of black hole growth characterized by dense gas envelopes. So far, the most direct evi…

During cosmic noon (), when both star formation and black hole growth peaked, galaxy mergers are predicted to trigger dual active galactic nuclei (AGN) that eventually co…
Where Galaxies Go to Die: The Environments of Massive Quiescent Galaxies at
Ian McConachie, Anna de Graaff, Michael V. Maseda +25
At low redshift, massive quiescent galaxies (MQGs) are most frequently found in massive, rich galaxy clusters, but at high redshift the trend is less clear. Here, we present spectr…
