VLA Goulds Belt Survey: 206 Radio Sources in the Perseus Star-Forming Region

A catalog of 206 radio sources detected in the Perseus star-forming complex using the Karl G. Jansky Very Large Array. The data includes 42 sources associated with young stellar objects and was collected in multi-epoch observations during 2011. The catalog was created by the HEASARC in February 2018 based on tables from the reference paper.

Use Cases

• Classifying radio emission mechanisms based on spectral index and variability data from dual-frequency, multi-epoch observations.
• Identifying candidate young stellar objects based on radio properties consistent with those described for 20 unidentified sources.
• Analyzing the relationship between non-thermal radio emission prevalence and the evolutionary status of young stellar objects.
• Comparing radio and X-ray observations to study the Güdel-Benz relation in star-forming regions.

Strengths

• Contains 206 detected radio sources with 42 identified as young stellar objects.
• Observations are high-resolution (~1 arcsecond) and fairly deep (~16 microJansky sensitivity).
• Dual-frequency (4.5 and 7.5 GHz) and multi-epoch strategy enables spectral index and variability characterization.

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 VLA configurations and targeted fields.
