VizieR Online Data Catalog: VLA/VLBA obscured radio-loud active galactic nuclei (Yan+, 2016)
Abstract
The specific selection criteria for the sample presented in Yan et al. 2012AJ....144..124Y (Paper I) include the presence of an SDSS r-band optical counterpart within 1.5" of a bright (>=0.5 Jy) FIRST radio source position and characteristics of the optical counterpart that favor it being a late-type galaxy. Of the 82 objects originally selected (Paper I), 2 are nearby galaxies at z<0.05 (J1352+3126 and J1413-0312) and are excluded from our discussion in this paper. Except when archive data were available, we observed all the sources at 4.9 and 8.5 GHz using the VLA of NRAO in its most extended A-configuration (VLA-A; project # AY0052). Overall, we obtained data for 35 sources at both frequencies, 14 at 4.9 GHz only, and 8 at 8.5 GHz only. Our data were taken during 2007 June to August in the transitional period from VLA to Expanded VLA (EVLA; currently the Karl G. Jansky VLA). We used the VLBA to obtain 1.4 GHz images for sources that are unresolved or have compact components in VLA-A images (project # BY0020). Overall, 36 sources were observed in 2009 December and 2010 January.
