Our release includes an interactive viewer where you can explore the images, display the spectroscopic redshifts (Khostovan et al. 2025) and information from the photometric catalog (including their full SED, photometric redshift, the cutout images in each filter, and the zPDF).

And finally, Shuntov et al. present the catalog, including photometric measurements in 37 bands (including #jwst, #hst, #spitzer, and ground-based telescopes), physical parameters (like redshift and stellar mass), and morphological parameters.

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

Along with the data, we have released three papers describing the data reduction and catalog process.
First, Franco et al. describe the NIRCam data reduction process and challenges for handling a dataset of this size. arxiv.org/abs/2506.03256
