A direct imaging search for wide (sub)stellar companions around rad-vel   planet host stars
  We present an overview of our ongoing systematic search for wide (sub)stellar companions around the stars known to host rad-vel planets. By using a relatively large field of view and going very deep our survey can find all directly detectable stellar and brown dwarf companions (m>40 Mjup) within a 1000 AU orbit.
