Unveiling the radio counterparts of two binary AGN candidates:
  J1108+0659 and J1131-0204
  The sources SDSS\,J113126.08-020459.2 and SDSS\,J110851.04+065901.4 are two
double-peaked [O III] emitting AGN, identified as candidate binary AGNs by
optical and near infrared (NIR) observations. We observed the two sources with
high resolution Very Long Baseline Interferometry (VLBI) using the European
VLBI Network at 5\,GHz, reduced VLA observations at three frequencies available
for one of the sources, and used archival HST observations.
  For the source SDSS\,J113126.08-020459.2, the VLBI observations detected only
one single compact component associated with the eastern NIR nucleus. In
SDSS\,J110851.04+065901.4, the VLBI observations did not detect any compact
components, but the VLA observations allowed us to identify a possible compact
core in the region of the north-western optical/NIR nucleus. In this source we
find kpc-scale extended radio emission that is spatially coincident to the
ultraviolet continuum and to the extended emission narrow line region. The UV
continuum is significantly obscured since the amount of extended radio emission
yields a star formation rate of about 110 \msunyr, which is an order of
magnitude larger than implied by the observed ultraviolet emission.
  Our analysis confirms the presence of only one AGN in the two candidate
binary AGNs.
