Radio and X-ray Observations of the Possible New Gamma-ray binary HESS J0632+057

Abstract : HESS J0632+057 is one of the only point-like, unidentified TeV sources in our galaxy. The association of this source with the massive B0pe star MWC 148 has led to the suggestion that HESS J0632+057 could be a new gamma-ray binary system. Our recent X-ray observations with XMM-Newton have revealed a non-thermal, point-like source coincident with this star, further strengthening the identification of HESS J0632+057 as a high mass X-ray binary system. Here we present new Very Large Array (VLA) and Giant Metre-wave Radio Telescope (GMRT) observations towards HESS J0632+057 which reveal point-like variable emission at the location of MWC 148.
