X-ray Characterization of Galaxy Groups and Hickson Groups in COSMOS-Web to z~3.8 I. X-ray Luminosity Function Evolution
Ghassem Gozaliasl, Günther Hasinger, Gavin Leroy +35
Galaxy groups are the dominant halo environment in the Universe and a sensitive laboratory for feedback and gas-cycling physics, yet a uniform, intermediate-redshift X-ray characte…
CHAMPS: Data Reduction and Detection of ~3300 Dusty Galaxies at 1.2 mm
Felix Martinez, Jeyhan S. Karaltepe, Andreas L. Faisst +52
We present the reduction and source catalogs for the \textit{COSMOS High- ALMA-MIRI Population Survey} (CHAMPS), the largest Atacama Large (Sub)Millimeter Array (ALMA) blank fie…
CHAMPS: The COSMOS High-Redshift ALMA-MIRI Population Survey - A New Census of the Dusty Early Universe
Andreas L. Faisst, Felix Martinez, Jeyhan S. Kartaltepe +86
Understanding how dust forms and evolves over cosmic time is a key open problem in extragalactic astrophysics. Galaxies in the early Universe were once thought to be mostly dust-po…
Rest-Frame UV and Optical Structural Evolution of Narrowband-Selected Lyman-alpha Emitters at z = 2-7 with JWST/NIRCam
Ronaldo Laishram, Haruka Kusakabe, Satoshi Kikuta +8
We present a systematic study of the rest-frame ultraviolet (UV) and optical morphologies of Ly emitters (LAEs) at - from the SILVERRUSH multi-narrowband catalog,…
Quiescent Galaxies at from CAPERS spectroscopy and their Number densities
Lu Shen, Weida Hu, Casey Papovich +28
Recent JWST observations have revealed an overabundance of quiescent galaxies at high redshift. Photometric methods, such as photometry-derived sSFRs, colors, and synthetic $…
COSMOS-Web: A Multi-wavelength Morphological Catalog of ~780,000 Galaxies
Lilan Yang, Jeyhan S. Kartaltepe, Nicole E. Drakos +20
We present multi-wavelength morphological measurements for all galaxies in the COSMOS-Web survey, i.e., 780,000 galaxies contained in the COSMOS2025 catalog. We perform both…
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…
COSMOS-Web galaxy groups: Evolution of red sequence and quiescent galaxy fraction
Greta Toni, Matteo Maturi, Gianluca Castignani +33
We investigate the redshift and group richness dependence of the quiescent fraction and red-sequence (RS) parameters in COSMOS galaxy groups from z=0 to z=3.7. We analyzed the deep…
COSMOS Web: Morphological quenching and size-mass evolution of brightest group galaxies from z = 3.7
Ghassem Gozaliasl, Lilan Yang, Jeyhan Kartaltepe +47
We present a comprehensive study of the structural evolution of Brightest Group Galaxies (BGGs) from redshift to using the \textit{James Webb Space Telesc…
COSMOS-Web: Comprehensive Data Reduction for Wide-Area JWST NIRCam Imaging
Maximilien Franco, Caitlin M. Casey, Anton M. Koekemoer +37
We present the data reduction methodology used for the COSMOS-Web survey JWST NIRCam data. Covering 0.54 deg^2 with four broadband filters (F115W, F150W, F277W, F444W) and a total…
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…
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…
