z0MGS DR1: Nearby Galaxy Atlas with WISE and GALEX Images

z0MGS DR1 is an archival project from NASA combining WISE and GALEX images of nearby galaxies. The main sample consists of approximately 11,000 galaxies likely within 50 megaparsecs, with an additional ~5,000 galaxies included. The dataset provides integrated stellar mass and star formation rate measurements for each galaxy.

Use Cases

• Analyze galaxy morphology and structure based on combined WISE and GALEX imagery.
• Model star formation rates in nearby galaxies based on integrated photometry data.
• Study the correlation between stellar mass and ultraviolet emission from galaxies.
• Train machine learning models for galaxy classification using multi-band satellite images.

Strengths

• Main sample of ~11,000 galaxies selected with specific distance and brightness criteria.
• Includes imagery from two major satellite missions: WISE and GALEX.
• 15,716 galaxies have coverage in all four WISE bands, providing consistent multi-wavelength data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown for the full dataset, which may limit suitability assessment.
• The description notes ~5,000 additional galaxies do not meet the formal selection criteria, potentially introducing heterogeneity.
