A PANORAMIC of UV-optical morphologies of "Little Red Dots": Two groups of LRDs distinguished by UV half-light radius

Aidan P. Cloonan, Katherine E. Whitaker, Sinclaire M. Manning +13

Among the most remarkable results from JWST is the discovery of abundant, compact, and very red sources in the early Universe known as "Little Red Dots" (LRDs). The relative degree…

The Engine and its Flows: Little Red Dot spectra are shaped by the column densities of their gas envelopes

Jorryt Matthee, Alberto Torralba, Gabriele Pezzulli +23

JWST data have enabled the abundant identification of compact broad Balmer line sources nicknamed the Little Red Dots. While they share broad lines with active galactic nuclei, the…

Everything Every Band All at Once II: The Relationship Between Optical Size and Stellar Mass Over Eight Billion Years of Cosmic History

Tim B. Miller, Yunchong Zhang, Sedona H. Price +24

While the size-mass relation provides insight into the structural evolution of galaxies, the data available and methods employed have hindered our ability to study a detailed and c…

Evidence for Shallow Nebular Attenuation Curves and Patchy Dust Geometry at z~2 with Pa-beta/H-alpha Measurements from JWST-MegaScience Medium Band Photometry

Brian Lorenz, Katherine A. Suess, Mariska Kriek +25

We constrain the nebular attenuation curve and investigate dust geometry in star-forming galaxies at cosmic noon using photometric medium-band emission line measurements. We measur…

Water absorption confirms cool atmospheres in two little red dots

Bingjie Wang, Joel Leja, Ivo Labbe +35

Little red dots (LRDs) are an abundant population of compact high-redshift sources with red rest-frame optical continua, discovered by the James Webb Space Telescope (JWST). Their…

From Grism to IFU: Revising the Redshift and Nature of the Massive Dusty Galaxy S1 with JWST and ALMA

Mengyuan Xiao, Longji Bing, Gabriel Brammer +21

We report a revised spectroscopic redshift for the dusty massive galaxy S1, previously inferred with an exceptionally high baryon-to-star conversion efficiency from NIRCam slitless…
