Free-Free Radio Emission from Little Red Dots as a Probe of Ionized Gas
Takumi S. Tanaka, Kohei Inayoshi, Zu Yan +3
Recent studies have hypothesized that little red dots (LRDs) are rapidly accreting black holes surrounded by dense gaseous environments. Both neutral and ionized gas play a key rol…
The Roman eXtreme Deep Field (RXDF)
Haojing Yan, Anton M. Koekemoer, Yue Shen +127
The Roman eXtreme Deep Field (RXDF) program is one of the five General Astrophysics Survey (GAS) programs approved for observing time with the Nancy Grace Roman Space Telescope in…
The UV Side of Little Red Dots: Red, Compact, and Iron-Enhanced Rest-UV Emission with a Strong Downturn around Ly
Makoto Ando, Yuichi Harikane, Harley Katz +2
Little Red Dots (LRDs) are candidates for growing supermassive black holes newly discovered by the James Webb Space Telescope (JWST), characterized by compact rest-optical morpholo…
COSMOS-3D: Black Hole Mass Estimators and Luminosity Functions of Paschen-line AGNs
Danyang Jiang, Linhua Jiang, Shuqi Fu +13
Near-IR Paschen lines are potentially an excellent tracer of Type 1 AGNs that is hardly affected by dust extinction. JWST allows us, for the first time, to explore Paschen-line obj…
ALMA and JWST Identification of Faint Dusty Star-Forming Galaxies up to z~8
Jorge A. Zavala, Andreas L. Faisst, Manuel Aravena +44
We exploit a new sample of around 400 bright dusty galaxies from the ALMA CHAMPS Large Program, together with the rich JWST multi-band data products in the COSMOS field, to explore…
Extended Components of Little Red Dots in the Rest-Frame Optical
Yiyang Zhang, Xuheng Ding, Lilan Yang +26
Recent JWST observations have revealed a population of red, compact, high-redshift objects called Little Red Dots (LRDs), whose host components have remained largely unconstrained,…
Physical properties of galaxies and the UV Luminosity Function from to in COSMOS-Web
Maximilien Franco, Caitlin M. Casey, Hollis B. Akins +37
We present measurements of the rest-frame ultraviolet luminosity function (UVLF) in three redshift bins over -14 from the JWST COSMOS-Web survey. Our samples, selected us…
Discovery of a Little Red Dot candidate at in COSMOS-Web based on MIRI-NIRCam selection
Takumi S. Tanaka, Hollis B. Akins, Yuichi Harikane +64
JWST has revealed a new high-redshift population called little red dots (LRDs). Since LRDs may be in the early phase of black hole growth, identifying them in the early universe is…
The Cosmic Owl: Twin Active Collisional Ring Galaxies with Starburst Merging Front at
Mingyu Li, Bjorn H. C. Emonts, Zheng Cai +12
Galaxy mergers play a critical role in driving galaxy evolution, especially by transforming galaxy morphology, redistributing gas around galaxies, triggering active galactic nuclei…
An upper limit of 10 M in dust from ALMA observations in 60 Little Red Dots
Caitlin M. Casey, Hollis B. Akins, Steven L. Finkelstein +9
By virtue of their red color, the dust in little red dots (LRDs) has been thought to be of appreciable influence, whether that dust is distributed in a torus around a compact activ…
A PAH deficit in the starburst core of a distant spiral galaxy
Zhaoxuan Liu, John D. Silverman, Emanuele Daddi +32
We present high-resolution and spatially-matched observations with JWST and ALMA of a starburst galaxy (PACS-830) at . The NIRCam observations mainly trace the stellar ligh…
SHELLQs-JWST Unveils the Host Galaxies of 12 Quasars at z>6
Xuheng Ding, Masafusa Onoue, John D. Silverman +35
The advent of JWST has opened new horizons in the study of quasar host galaxies during the reionization epoch (z>6). Building upon our previous initial measurements of stellar ligh…
COSMOS-Web: Unraveling the Evolution of Galaxy Size and Related Properties at
Lilan Yang, Jeyhan S. Kartaltepe, Maximilien Franco +26
We measure galaxy sizes from using COSMOS-Web, the largest-area JWST imaging survey to date, covering 0.54 deg. We analyze the rest-frame optical (~5000A) si…
Bridging Quasars and Little Red Dots: Insights into Broad-Line AGNs at from the First JWST COSMOS-3D Dataset

``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…
