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…

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…

The ionizing properties of JWST's compact broad-line emitters

Sara Mascia, Jorryt Matthee, Alberto Torralba +4

The recent JWST discovery of a numerous population of broad-line emitters (BLEs) at has reopened the question of whether sources other than faint galaxies contributed signifi…

Little Red Dots at z~2 in EIGER reveal a gentle decline with respect to their peak number density at z~5

Shrriya Kapoor, Jorryt Matthee, Alberto Torralba +10

We report the discovery of a sample of little red dots (LRDs) at identified from deep JWST/NIRCam imaging and wide-field slitless spectroscopy over arcmin f…

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…

A new sample of Little Red Dots at in DESI DR1: Broad Balmer lines, low ionization spectrum and no variability

Kevin Park, Alberto Torralba, Jorryt Matthee +4

JWST has unveiled an abundant population of compact broad-line emitters largely at , the Little Red Dots (LRDs), which might represent a previously unprobed supermassive…

All the Massive Galaxy Overdensities during Reionization: JWST Rest-Frame Optical Selection Reveals Young, Chemically Evolved Galaxies Embedded in Dense, Neutral Gas at z > 5

Chamilla Terp, Kasper E. Heintz, Jorryt Matthee +7

The high-redshift progenitors of present-day galaxy clusters are believed to substantially contribute to the global star-formation rate density and drive the large-scale reionizati…

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…
