Phoenix Deep Survey: 1.4-GHz Radio Source Catalog for Galaxy Evolution

Observations from 1994 to 2001 with the Australia Telescope Compact Array compiled a homogeneous radio-selected catalog of over 2000 sources. The mosaic image covers 4.56 square degrees, reaching a sensitivity of 12 microJy rms noise, and was produced by NASA. The catalog is intended for investigating star formation evolution across the redshift range 0 < z < 1.

Use Cases

• Modeling galaxy evolution based on a homogeneous radio-selected sample avoiding optical obscuration.
• Analyzing 1.4 GHz source counts and flux density distributions from the compiled catalog.
• Cross-referencing radio sources with complementary multicolor optical, near-infrared, and spectroscopic data for multi-wavelength studies.
• Investigating star formation history spanning the redshift range 0 < z < 1 using the catalog's consistent measurements.

Strengths

• Catalog contains over 2000 sources with flux densities as faint as 60 microJy.
• Mosaic covers 4.56 square degrees with a high sensitivity of 12 microJy rms noise.
• Source parameter measurements are reported to be consistent with expected uncertainties from image noise and fitting procedures.
• Based on 523 hours of observing time across multiple array configurations from 1994 to 2001.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect observational bias inherent to the specific high-latitude region surveyed.
