COSMOS2025
Listed in IVOA Registry (Virtual Observatory)
We present COSMOS2025, the COSMOS-Web catalog of photometry, morphology, photometric redshifts and physical parameters for more than 700000 galaxies in the Cosmic Evolution Survey (COSMOS) field.
Description
This catalog is based on our James Webb Space Telescope 255h COSMOS-Web program, which provides deep near-infrared imaging in four NIRCam (F115W, F150W, F277W, F444W) and one MIRI (F770W) filter over the central ~0.54deg^2^ (~0.2deg^2^ for MIRI) in COSMOS.
These data are combined with ground- and space-based data to derive photometric measurements of NIRCam-detected sources using both fixed-aperture photometry (on the space-based bands) and a profile-fitting technique on all 37 bands spanning 0.3-8 micron. We provide morphology for all sources from complementary techniques including profile fitting and machine-learning classification. We derive photometric redshifts, physical parameters and non-parametric star formation histories from spectral energy distribution (SED) fitting.

The catalog has been extensively validated against previous COSMOS catalogs and other surveys. Photometric redshift accuracy measured using spectroscopically confirmed galaxies out to z~9 reaches {sigma}_MAD_=0.012 at m_F444W_<28 and remains at {sigma}_MAD_<~0.03 as a function of magnitude, color, and galaxy type. This represents a factor of ~2 improvement at 26 AB mag compared to COSMOS2020.
The catalog is approximately 80% complete at log(M*/M_{sun}_)~9 at z~10 and at log(M*/M_{sun}_)~7 at z~0.2, representing a gain of 1dex compared to COSMOS2020. COSMOS2025 represents the definitive COSMOS-Web catalog. It is provided with complete documentation, together with redshift probability distributions, and it is ready for scientific exploitation today.
