The population of radio sources in the field of the unidentified   gamma-ray source TeV J2032+4130
  TeV J2032+4130 is the first extended very high energy gamma-ray source, which has remained enigmatic since its discovery, due to the lack of identification. We report here deep radio observations covering the TeV J2032+4130 field and revealing for the first time an extended and diffuse radio emission, as well as a remarkable population of compact radio sources. Some of these radio sources are in positional coincidence with X-ray and optical/IR sources. Future follow up studies of these new radio sources will likely contribute to solve the mystery of this extended unidentified TeV source.
