ALMA detection of [OIII] 88um at z=12.33: Exploring the Nature and Evolution of GHZ2 as a Massive Compact Stellar System
Jorge A. Zavala, Tom Bakx, Ikki Mitsuhashi +21
We present ALMA observations on the high-redshift galaxy GHZ2 and report a successful detection of the rest-frame 88um atomic transition from doubly-ionized Oxygen at z=12.3327+/-0…
Strong rest-UV emission lines in a "little red dot" AGN at : Early SMBH growth alongside compact massive star formation?
Hollis B. Akins, Caitlin M. Casey, Danielle A. Berg +11
JWST has now revealed a population of broad-line AGN at characterized by a distinctive SED shape, with very red rest-frame optical and very blue rest-frame UV continuum. Whil…
Crimson Behemoth: a Massive Clumpy Structure Hosting a Dusty AGN at
Takumi S. Tanaka, John D. Silverman, Yurina Nakazato +40
The current paradigm for the co-evolution of galaxies and their supermassive black holes postulates that dust-obscured active galactic nuclei (AGNs) represent a transitional phase…
Not-so-little Red Dots: Two massive and dusty starbursts at z~5-7 pushing the limits of star formation discovered by JWST in the COSMOS-Web survey
Fabrizio Gentile, Caitlin M. Casey, Hollis B. Akins +24
We present the properties of two candidate massive () and dusty ( mag) galaxies at in the first 0.28 deg of the COSMOS-Web sur…
The Extended Mapping Obscuration to Reionization with ALMA (Ex-MORA) Survey: 5 Source Catalog and Redshift Distribution
Arianna S. Long, Caitlin M. Casey, Jed McKinney +41
One of the greatest challenges in galaxy evolution over the last decade has been constraining the prevalence of heavily dust-obscured galaxies in the early Universe. At , thes…
SCUBADive I: JWST+ALMA Analysis of 289 sub-millimeter galaxies in COSMOS-Web
Jed McKinney, Caitlin M. Casey, Arianna S. Long +36
JWST has enabled detecting and spatially resolving the heavily dust-attenuated stellar populations of sub-millimeter galaxies, revealing detail that was previously inaccessible. In…
Silencing the Giant: Evidence of AGN Feedback and Quenching in a Little Red Dot at z = 4.13
Vasily Kokorev, John Chisholm, Ryan Endsley +8
The James Webb Space Telescope (JWST) has uncovered a ubiquitous population of dust-obscured compact sources at . Many of these objects exhibit signs of active galactic…
A photo-z cautionary tale: Redshift confirmation of COSBO-7 at z=2.625
Shuowen Jin, Nikolaj B. Sillassen, Jacqueline Hodge +21
Photometric redshifts are widely used in studies of dusty star-forming galaxies (DSFGs), but catastrophic photo- failure can undermine all redshift-dependent results. Here we re…
Dust in Little Red Dots
Caitlin M. Casey, Hollis B. Akins, Vasily Kokorev +5
JWST has revealed a ubiquitous population of ``little red dots'' (LRDs) at , selected via their red rest-frame optical emission and compact morphologies. They are though…
COSMOS-Web: The over-abundance and physical nature of "little red dots"--Implications for early galaxy and SMBH assembly
Hollis B. Akins, Caitlin M. Casey, Erini Lambrides +38
JWST has revealed a population of compact and extremely red galaxies at , which likely host active galactic nuclei (AGN). We present a sample of 434 ``little red dots'' (LRDs)…
The Rise of Faint, Red AGN at : A Sample of Little Red Dots in the JWST Extragalactic Legacy Fields
Dale D. Kocevski, Steven L. Finkelstein, Guillermo Barro +54
We present a sample of 341 "little red dots" (LRDs) spanning the redshift range using data from the CEERS, PRIMER, JADES, UNCOVER and NGDEEP surveys. Unlike past use of…
Evidence of extreme ionization conditions and low metallicity in GHZ2/GLASS-z12 from a combined analysis of NIRSpec and MIRI observations
Antonello Calabro, Marco Castellano, Jorge A. Zavala +19
GHZ2/GLASS-z12 has been recently observed by JWST with both NIRSpec and MIRI spectrographs, making it the most distant galaxy () with complete spectroscopic coverag…
Efficient PSF Modeling with ShOpt.jl: A PSF Benchmarking Study with JWST NIRCam Imaging
Edward Berman, Jacqueline McCleary, Anton M. Koekemoer +13
With their high angular resolutions of 30--100 mas, large fields of view, and complex optical systems, imagers on next-generation optical/near-infrared space observatories, such as…
