Faint radio sources in the NOAO Bootes field
Listed in IVOA Registry (Virtual Observatory)
As a step toward investigating the parsec-scale properties of faint extragalactic radio sources, the Very Long Baseline Array (VLBA) was used at 5.0GHz to obtain phase-referenced images of 76 sources in the NOAO Bootes field.
Description
These 76 sources were selected from the Faint Images of the Radio Sky at Twenty cm (FIRST) catalog to have peak flux densities above 10mJy at 5" resolution and deconvolved major diameters of less than 3" at 1.4GHz.
Of these faint radio sources, 57 were identified with accretion-powered radio galaxies and quasars brighter than 25.5mag in the optical I band. On Very Large Array (VLA) scales at 1.4GHz, a measure of the compactness of the faint sources (the ratio of the peak flux density from FIRST to the integrated flux density from the NRAO VLA Sky Survey catalog) spans the full range of possibilities arising from source-resolution effects.
