Double Dots: Compact Pairs Mark Little Red Dots and High-Redshift Broad-line AGNs
A. J. Barger, L. L. Cowie
We utilize JWST imaging of the massive lensing cluster field A2744 to find close pairs of compact sources with separations less than 0.25". A large fraction of these "Double Dots"…
A Redshift-based Red Selection of Dusty Star-forming Galaxies
A. J. Barger, L. L. Cowie, S. J. McKay +1
We use JWST observations (1.5 micron to 4.44 micron), together with complete ALMA observations (870 micron and/or 1.2 mm), of the massive lensing cluster field A2744 to show that g…
Molecular Gas Detections in Eight Faint DSFGs with Red NIR Colors at z = 1.2-2.5
Michael J. Nicandro Rosenthal, Stephen J. McKay, Amy J. Barger +1
We present a NOEMA survey of CO(3-2), CO(4-3), and [C I](P-P) in eight faint (average mJy) dusty star-forming galaxies (DSFGs) at $z = 1.2-2…
The Physical Properties and Morphologies of Faint Dusty Star-forming Galaxies Identified with JWST
Stephen J. McKay, Amy J. Barger, Lennox L. Cowie +1
We identify a sample of 234 dusty star-forming galaxies (DSFGs) in the A2744 and GOODS-S fields using JWST/NIRCam-selected galaxies as priors for SCUBA-2 measurements. This method…
Spectroscopic Ultraluminous Ly-alpha Luminosity Functions at z = 5.7 and z = 6.6 from HEROES: Evidence for Ionized Bubbles
A. J. Taylor, A. J. Barger, L. L. Cowie +2
We present spectroscopic Ly luminosity functions (LFs) at z = 5.7 and z = 6.6 based on a large 209 source sample of Ly emitter (LAE) candidates identified in Subaru/Hyper S…
