COSMOS2025 is an extensive galaxy catalog from the COSMOS-Web survey using JWST, offering deep near-infrared imaging and detailed galaxy properties for over 700,000 sources. This catalog significantly improves photometric redshift accuracy and mass completeness, enabling advanced studies of galaxy evolution across cosmic time.

Why it matters: It doubles photometric redshift precision at faint magnitudes compared to previous COSMOS catalogs.

The big picture: COSMOS2025 covers 0.54 deg² with 37-band photometry and morphology, supporting comprehensive galaxy evolution research.

Stunning stat: The catalog is 80% complete down to stellar masses of 10^9 M☉ at redshift ~10, a 10x improvement.

Quick takeaway: COSMOS2025 provides precise redshifts and physical parameters for 700,000+ galaxies, ready for immediate scientific use.
