COSMOS-Web: does halo mass alone shape the clustering of star-forming and quiescent galaxies?
Louise Paquereau, Clotilde Laigle, Henry Joy McCracken +29
While stellar mass correlates strongly with halo mass, it remains unclear whether halo mass alone governs galaxy star-formation activity, or whether secondary halo properties and e…
The NIRISS PASSAGE Spectroscopic Redshift Catalog in COSMOS
Mason S. Huberty, Kalina V. Nedkova, Zahra Sattari +34
We present the Parallel Application of Slitless Spectroscopy to Analyze Galaxy Evolution (PASSAGE) spectroscopic redshift catalog in the COSMOS field. PASSAGE is a JWST Cycle 1 Nea…
Expanding the High-z Supernova Frontier: "Wide-Area" JWST Discoveries from the First Two Years of COSMOS-Web
Ori D. Fox, Armin Rest, Justin D. R. Pierel +48
Transient astronomy in the early Universe (z > 2) remains largely unexplored, lying beyond the rest-frame optical spectroscopic reach of most current observatories. Yet this regime…
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…
Multi-wavelength morphology and dust emission in low-redshift dwarf galaxies in COSMOS-Web with HST and JWST
D. Kakkad, I. Lazar, S. Harish +18
Low-mass or dwarf galaxies (M M) are abundant in the Universe, yet their formation and evolution remain poorly understood. Their enhanced sensitivity to fe…
COSMOS-Web: Estimating Physical Parameters of Galaxies Using Self-Organizing Maps
Fatemeh Abedini, Ghassem Gozaliasl, Akram Hasani Zonoozi +38
The COSMOS-Web survey, with its unparalleled combination of multiband data, notably, near-infrared imaging from JWST's NIRCam (F115W, F150W, F277W, and F444W), provides a transform…
