The Role of Environment in Shaping the Assembly Timelines of Massive Quiescent Galaxies at Cosmic Noon
Tianmu Gao, J. Trevor Mendel, Letizia Bugiani +10
JWST observations of massive quiescent galaxies (MQGs) at have revealed diverse star formation histories (SFHs). In this letter, we investigate whether these variations ar…
Discovery of the Lyman- Forest in a Star-Forming Galaxy at : Implications for the Timing and Topology of Cosmic Reionization
Jakob M. Helton, Joris Witstok, Marta Laska +15
The escape of ionizing photons from galaxies during the Epoch of Reionization is often inferred indirectly because the intervening neutral hydrogen in the intergalactic medium (IGM…
Calcium Triplet Absorption is Common around Little Red Dots
Jenny E. Greene, Hanpu Liu, Raphael E. Hviding +29
We present new evidence for an optically thick atmosphere surrounding Little Red Dots (LRDs) in the form of Ca absorption at rest-frame 8500A, the calcium triplet (CaT). Building o…
Balmer Absorption Series and Broad Metal Lines in Two Luminous Little Red Dots
Bingjie Wang, Jenny E. Greene, Hanpu Liu +21
Balmer absorption is common among little red dots (LRDs), but absorbers at or redward of systemic are rare, occurring in only \% of H absorbers. In this paper, we stu…
Overmassive No More: The Case for Little Red Dots Hosting Black Hole Seeds as Massive as Single Supermassive Stars
Wendy Q. Sun, Rohan P. Naidu, Hanpu Liu +17
Little Red Dots (LRDs) display singular properties unlike any known class of AGN or galaxies, motivating novel mass estimators for their central engines. Inspired by their similari…
A Spectral Framework for Testing the Quasi-Star Hypothesis in Little Red Dots I: Weighing LRDs by Their Super-Eddington Luminosity Ratios---No Signs of Overmassive Black Holes
Olivia Curtis, Nikko J. Cleri, Jakob M. Helton +2
We present a spectral test of the quasi-star hypothesis for Little Red Dots (LRDs) whereby a black hole grows inside a stellar-like envelope. We use Prospector to fit host galaxies…
