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…
SCUBADive II: Searching for Dust-Obscured Galaxies via F150W-Dropouts in COSMOS-Web
Sinclaire M. Manning, Jed McKinney, Katherine E. Whitaker +24
The relative fraction of obscured galaxies at compared to lower redshifts remains highly uncertain as accurate bookkeeping of the dust-obscured component proves difficult. We…
Going deeper into the dark with COSMOS-Web: JWST unveils the total contribution of Radio-Selected NIRfaint galaxies to the cosmic Star Formation Rate Density
Fabrizio Gentile, Margherita Talia, Andrea Enia +34
We present the first follow-up with JWST of radio-selected NIRfaint galaxies as part of the COSMOS-Web survey. By selecting galaxies detected at radio frequencies ($S_{\rm 3 GHz}>1…
Clumps as multiscale structures in cosmic noon galaxies
Boris S Kalita, Tomoko L Suzuki, Daichi Kashino +31
Star-forming clumps have been found to significantly influence the star formation of gas-rich galaxies. Using public data from JWST/NIRCam (COSMOS-Web) and ALMA (FMOS-COSMOS)…
Behind the dust veil: A panchromatic view of an optically dark galaxy at z=4.82
Nikolaj B. Sillassen, Shuowen Jin, Georgios E. Magdis +30
Optically dark dusty star-forming galaxies (DSFGs) play an essential role in massive galaxy formation at early cosmic time, however their nature remains elusive. Here we present a…
Hidden in Pixels. I. Discovery of dual "little red dots" indicates excess clustering on kilo-parsec scales
Takumi S. Tanaka, John D. Silverman, Kazuhiro Shimasaku +56
``Little Red Dots'' (LRDs) are an abundant high-redshift population newly discovered by the James Webb Space Telescope (JWST) and considered to be an early growth phase of supermas…
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…
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…
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)…
Tracing the rise of supermassive black holes: A panchromatic search for faint, unobscured quasars at z > 6 with COSMOS-Web and other surveys
Irham T. Andika, Knud Jahnke, Masafusa Onoue +20
We report the identification of 64 new candidates of compact galaxies, potentially hosting faint quasars with bolometric luminosities of --10 erg s…
The relation up to through decomposition of COSMOS-Web NIRCam images
Takumi S. Tanaka, John D. Silverman, Xuheng Ding +25
Our knowledge of relations between supermassive black holes and their host galaxies at is still limited, even though being actively sought out to . Here, we use…
