COSMOS: Real Galaxy Images from the HST Survey

COSMOS real galaxy dataset contains images of real galaxies extracted from the Hubble Space Telescope (HST) COSMOS survey. The dataset was created by Rachel Mandelbaum of Carnegie Mellon University for use with the GalSim software. The specific number of images, file formats, and last update date are not provided in the available metadata.

Use Cases

• Simulating realistic galaxy observations based on real HST survey data.
• Testing galaxy shape measurement algorithms against real galaxy images.
• Benchmarking image processing pipelines for astronomical surveys.
• Training generative models for astronomical image synthesis.

Strengths

• Data originates from the authoritative Hubble Space Telescope COSMOS survey.
• Dataset is associated with a specific author (Rachel Mandelbaum) and institution (Carnegie Mellon University).
• Designed for a specific, documented purpose: use with the GalSim software.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
