BEACON: JWST NIRCam Pure-parallel Imaging Survey. IV. A Systematic Search for Galaxy Overdensities and Evidence for Gas Accretion Mode Transition
Ryo Albert Sutanto, Takahiro Morishita, Tadayuki Kodama +20
We systematically search for galaxy overdensities using 20 independent fields with a minimum of six filters (F090W, F115W, F150W, F277W, F356W, and F444W) from BEACON, the JWST Cyc…
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…
Black Hole Stars Across the Universe: Identifying Central Engine Dominated Little Red Dots at
Andrea Weibel, Rohan P. Naidu, Pascal A. Oesch +16
Photometric selections of Little Red Dots (LRDs) largely rely on identifying their ``V-shaped'' spectral energy distribution (SED). Recent work suggests this V-shape stems from a c…
Pristine Massive Star Formation Caught at the Break of Cosmic Dawn
Takahiro Morishita, Zhaoran Liu, Massimo Stiavelli +3
The existence of galaxies with no heavy elements is a key prediction of cosmological models. So far no "zero-metallicity", or Population~III, galaxies have been identified. Here, w…
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…
