Ripples in the OCEANS: Broad Line Variability of Little Red Dots

Madisyn Brooks, Kelcey Davis, Jonathan R. Trump +16

Little Red Dots (LRDs) are a unique class of compact, red sources discovered in the JWST extragalactic deep fields. Determining if they are indeed powered by accreting supermassive…

Little Red Dots on FIRE: Exploring the formation and observational signatures of ultra-compact early galaxies

Niranjan Chandra Roy, Daniel Anglés-Alcázar, Rachel K. Cochrane +15

Little Red Dots (LRDs) are compact sources with broad Balmer lines, Balmer breaks, anomalous UV emission, rising red continuum, and uncertain origin. We use FIRE cosmological simul…

OCEANS of Absorption: High-resolution NIRSpec Spectroscopy Reveals Diverse Balmer-line Absorption in Little Red Dots

Kelcey Davis, Madisyn Brooks, Raymond C. Simons +24

The ``Little Red Dots' (LRDs) that appeared in JWST deep field images have been the subject of significant study since their discovery. In this work, we present high-resolution fol…

A Rapid Evolution in the Observed Mbh/M* Relation at z > 3 Revealed via Spectro-photometric SED-Modeling

Ansh R. Gupta, Anthony Taylor, Emma Curtis-Lake +33

Spectroscopic observations from JWST have uncovered a plethora of active galactic nuclei (AGN) at z > 4 with black hole (BH) mass (Mbh) to stellar mass (M*) ratios significantly ab…

Extreme Emission Line Galaxies in CEERS Are Powered by Star Formation, not AGN

Kelcey Davis, Madisyn Brooks, Jonathan R. Trump +28

We present a spectroscopic study of photometrically identified extreme emission-line galaxies (EELGs) with observed-frame equivalent widths (EWs) >5000 A of either H alpha or H bet…

From "The Cliff" to "Virgil": Mapping the Spectral Diversity of Little Red Dots with JWST/NIRSpec

Guillermo Barro, Pablo G. Perez-Gonzalez, Dale Kocevski +26

One of JWST's most unexpected discoveries is the emergence of "Little Red Dots'' (LRDs): compact sources at with blue rest-frame UV continua, red optical slopes, and…

Beyond the Monsters: A More Complete Census of Black Hole Activity at Cosmic Dawn

Madisyn Brooks, Jonathan R. Trump, Raymond C. Simons +19

JWST has revealed an abundance of low-luminosity active galactic nuclei (AGN) at high redshifts (), pushing the limits of black hole (BH) science in the early Universe. Resu…

CAPERS-LRD-z9: A Gas Enshrouded Little Red Dot Hosting a Broad-line AGN at z=9.288

Anthony J. Taylor, Vasily Kokorev, Dale D. Kocevski +49

We present CAPERS-LRD-z9, a little red dot (LRD) which we confirm to be a broad-line AGN (BLAGN). First identified as a high-redshift LRD candidate from PRIMER NIRCam pho…

Here There Be (Dusty) Monsters: High Redshift AGN are Dustier Than Their Hosts

Madisyn Brooks, Raymond C. Simons, Jonathan R. Trump +13

JWST spectroscopy has discovered a population of galaxies with broad Balmer emission lines, and narrow forbidden lines, that are consistent with hosting active gala…
