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…

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…
