COSMOS Zamojski Morphology Catalog: Galaxy Survey Over 2 Square Degrees

Over 2 million galaxies detected in the COSMOS astronomical survey, spanning 75% of the age of the universe. The catalog was created by NASA from objects selected from a 2005 ground-based photometry release, with I-band magnitude <= 23. It covers a 2 square degree equatorial field imaged by major space and ground-based telescopes.

Use Cases

• Study galaxy formation and evolution based on the survey's focus on cosmic time and environment.
• Analyze galaxy morphology based on imaging from multiple major telescopes mentioned in the description.
• Train models for galaxy classification based on photometric data from a large, multi-wavelength survey.
• Conduct cosmological research based on data spanning a significant portion of the universe's age.

Strengths

• Over 2 million galaxies detected, providing a large sample size.
• Imaging data from multiple major space and ground-based telescopes, suggesting multi-wavelength coverage.
• Covers a 2 square degree equatorial field, offering a contiguous area for study.
• Data spans 75% of the age of the universe, enabling studies across cosmic time.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is derived from a 2005 photometry catalog release; newer observations may exist.
