The Balmer Absorber Strength Problem of Little Red Dots
Hanpu Liu, Eliot Quataert, Bingjie Wang +2
Little Red Dots (LRDs) commonly show Balmer absorption features. Some observed LRD spectra have weaker absorption in H than in H, in apparent contradiction to atomic physics…
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…
Little Red Dots As Super-Eddington Fountain Flows
Nicholas Kaaz, Eliot Quataert, Taya Govreen-Segal +1
Little red dots (LRDs) may be powered by supermassive black holes (SMBHs) accreting above the Eddington limit. Spectroscopy of LRDs often shows absorption troughs blueshifted by $\…
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…
Can Little Red Dots Contribute To The Early Universe Cosmic Dust Budget?
Chris Ashall, Rohan P. Naidu, Alberto Torralba +11
The origin of dust in the early Universe remains uncertain. We explore whether Little Red Dots (LRDs) could provide a high-redshift dust-production channel. Motivated by an analogy…
Little Red Dots as Intermediate Mass, Super-Eddington Engines: Insights from Type IIn Supernovae and The 1837-1856 Great Eruption of Carinae
Rohan P. Naidu, Jorryt Matthee, Anna de Graaff +20
JWST's Little Red Dots (LRDs) display a unique constellation of features that do not occur simultaneously in any other class of galaxies or AGN. Here we observe that many of these…
(LRDs): The Low-ReDshift Little Red Dots Survey. II. DESI DR1 Sample
Xiaojing Lin, Xiaohui Fan, Zheng Cai +12
JWST has revealed a substantial population of "Little Red Dots" (LRDs) at , challenging conventional AGN frameworks. However, the low-redshift regime remains largely unexplore…
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…
Spectral Appearance of Self-gravitating Disks Powered by Stellar Objects: Universal Effective Temperature in the Optical Continuum and Application to Little Red Dots
Yi-Xian Chen, Hanpu Liu, Ruancun Li +6
We revisit the spectral appearance of extended self-gravitating accretion disks surrounding compact central objects such as supermassive black holes. Using dust-poor opacities, we…
What you see is what you get: empirically measured bolometric luminosities of Little Red Dots
Jenny E. Greene, David J. Setton, Lukas J. Furtak +27
New populations of red active galactic nuclei (known as ``Little Red Dots'') discovered by JWST exhibit remarkable spectral energy distributions. Leveraging X-ray through far-infra…
The Discovery of Little Red Dots in the Local Universe: Signatures of Cool Gas Envelopes
Xiaojing Lin, Xiaohui Fan, Zheng Cai +25
JWST observations have revealed a population of high-redshift "little red dots" (LRDs) that challenge conventional AGN models. We report the discovery of three local LRDs at $z = 0…
