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…

COSMOS-3D: Dense Circumnuclear Gas across Black Hole Growth Phases at z ~ 3

Zi-Jian Li, Siwei Zou, Jianwei Lyu +25

We report the discovery of two broad-line X-ray AGNs (cid_414 and cid_947) at z ~ 3 identified in the JWST Cycle 3 COSMOS-3D program using NIRCam F444W grism spectroscopy. Both exh…

JWST COSMOS-3D: Spectroscopic Census and Luminosity Function of [O III] Emitters at 6.75<z<9.05 in COSMOS

Romain A. Meyer, Feige Wang, Koki Kakiichi +38

We present a catalogue of spectroscopically selected [OIII]+Hb emitters at 6.75<z<9.05 and the resulting [OIII] 5008 ÅLuminosity Function (LF) in the COSMOS field. We leverage the…

A first look at quasar-galaxy clustering at

Jan-Torge Schindler, Joseph F. Hennawi, Frederick B. Davies +8

We present JWST observations of the environments surrounding two high-redshift quasars, J02520503 at and J10072115 at , which enable the first constraints…

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…

COSMOS2025: The COSMOS-Web galaxy catalog of photometry, morphology, redshifts, and physical parameters from JWST, HST, and ground-based imaging

Marko Shuntov, Hollis B. Akins, Louise Paquereau +55

We present COSMOS2025, the COSMOS-Web catalog of photometry, morphology, photometric redshifts and physical parameters for more than 700,000 galaxies in the Cosmic Evolution Survey…

SAPPHIRES: Extremely Metal-Poor Galaxy Candidates with at from Deep JWST/NIRCam Grism Observations

Tiger Yu-Yang Hsiao, Fengwu Sun, Xiaojing Lin +19

Population III stars, the hypothetical first generation metal-free stars, have yet to be discovered. Even after three years of successful JWST operations, studies have shown that m…

Mapping neutral islands during end stages of reionization with photometric intergalactic medium tomography

Sambit K. Giri, Koki Kakiichi, Michele Bianco +1

During the epoch of reionization (EoR), the first generation of luminous sources in our Universe emitted ionizing photons that almost completely ionized the gas in the intergalacti…

Insights on Metal Enrichment and Environmental Effect at with JWST ASPIRE/EIGER and Chemical Evolution Model

Zihao Li, Koki Kakiichi, Lise Christensen +15

We present the mass-metallicity relation (MZR) for a parent sample of 604 galaxies at with \OIII\ doublets detected, using the deep JWST/NIRCam wide field slitless sp…

Bridging Quasars and Little Red Dots: Insights into Broad-Line AGNs at from the First JWST COSMOS-3D Dataset

Xiaojing Lin, Xiaohui Fan, Feige Wang +30

We report the discovery of 13 broad-line AGNs at from the first 10% data of the JWST Cycle 3 Treasury Program COSMOS-3D. These AGNs are identified by their broad H o…

JWST ASPIRE: How Did Galaxies Complete Reionization? Evidence for Excess IGM Transmission around Emitters during Reionization

Koki Kakiichi, Xiangyu Jin, Feige Wang +23

The spatial correlation between galaxies and the Ly forest provides insights into how galaxies reionized the Universe. Here, we present initial results on the spatial cross-corr…
