IRAS 20126+4104: Chandra X-Ray and Radio Source Catalog for a Massive Star-Forming Region

The IRAS 20126+4104 massive star-forming region was observed with the Chandra ACIS-I instrument on 2003 March 17 for 39.35 ks and with the VLA at 6 cm on 2011 August 7. The catalog contains 150 X-ray sources and 13 radio sources, with 88 near-infrared counterparts identified from 2MASS and Spitzer data. The table was created by NASA HEASARC in March 2016 based on CDS catalog J/ApJS/219/41.

Use Cases

• Identify and analyze young stellar object clusters based on the inferred presence of at least 43 objects within 1.2 pc of IRAS 20126+4104.
• Study multi-wavelength source correlations based on X-ray, radio, near-infrared, and optical data mentioned in the description.
• Investigate variable radio sources based on the new source [MHA2015] VLA G78.1907+3.364 reported.
• Perform stellar population analysis using the Besançon simulation of Galactic stellar populations referenced in the description.

Strengths

• Contains 150 X-ray sources and 13 radio sources from coordinated Chandra and VLA observations.
• Augmented with 88 near-infrared counterparts from 2MASS and Spitzer archival data.
• Provides a specific exposure time of 39.35 ks for the Chandra observation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
