Optical and radio astrometry of the galaxy associated with FRB150418
  A fading radio source, coincident in time and position with the fast radio
burst FRB150418, has been associated with the galaxy WISE J071634.59-190039.2.
Subsequent observations of this galaxy have revealed that it contains a
persistent, but variable, radio source. We present e-MERLIN, VLBA, and ATCA
radio observations and Subaru optical observations of WISE J071634.59-190039.2
and find that the persistent radio source is unresolved and must be compact
(<0.01 kpc), and that its location is consistent with the optical centre of the
galaxy. We conclude that it is likely that WISE J071634.59-190039.2 contains a
weak radio AGN.
