z0MGS DR1: Nearby Galaxy Atlas with WISE and GALEX Images

The z0MGS archival project combines WISE and GALEX images of nearby galaxies. The main sample consists of approximately 11,000 galaxies with a high probability of being within 50 megaparsecs and having an absolute magnitude brighter than -18, plus images for about 5,000 additional galaxies. This dataset, released by NASA, includes an index with integrated stellar mass and star formation rate measurements for each galaxy.

Use Cases

• Classify galaxy types based on integrated stellar mass and star formation rate data.
• Train computer vision models for galaxy morphology using combined WISE and GALEX images.
• Analyze correlations between ultraviolet (GALEX) and mid-infrared (WISE) emissions for star formation studies.
• Study the properties of a large sample of nearby galaxies within 50 Mpc.

Strengths

• Includes a primary sample of ~11,000 galaxies meeting specific distance and brightness criteria.
• Provides combined multi-wavelength coverage from WISE and GALEX satellite missions.
• Contains integrated photometry measurements like stellar mass and star formation rate for analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The 'Simple Index' version excludes Integrated Photometry, Sample Definition Parameters, and Derived Parameters.
