Search for a Point-Source Counterpart of the Unidentified Gamma-Ray Source TeV J2032+4130 in Cygnus
We have made a multiwavelength study of the overlapping error boxes of the unidentified γ-ray sources TeV J2032+4130 and 3EG J2033+4118 in the direction of the Cygnus OB2 association (d = 1.7 kpc) in order to search for a pointsource counterpart of the first unidentified TeV source. Optical identifications and spectroscopic classifications for the brighter X-ray sources in ROSAT PSPC and Chandr...
متن کاملThe New Unidentified TeV Source in Cygnus (TeV J2032+4130): HEGRA IACT-System Results
The first unidentified TeV source in Cygnus is confirmed by follow-up observations carried out in 2002 with the HEGRA stereoscopic system of Čerenkov Telescopes. Using all ∼279 hrs of data, this new source TeV J2032+4130, is steady over the four years of data taking, is extended with radius 6.2′, and has a hard spectrum with photon index −1.9. Its location places it at the edge of the core of t...
متن کاملA Radio Counterpart for the Unidentified Tev Source Hess J1813-178: the Radio-gamma-ray Connection
We discovered independently the shell-type supernova remnant G12.82−0.02, recently reported by Brogan et al. (2005), which is coincident with the unidentified TeV gamma-ray source revealed in the HESS survey of the Galactic plane. Estimating the ambient starlight at the location of this source from the integrated Lyα luminosity of the nearby H II region W33, we conclude that inverse Compton emi...
متن کاملA Search for the Radio Counterpart of the Unidentified Gamma-ray Source 3EG J1410-6147
We have made radio continuum, H I and X-ray observations in the direction of the unidentified EGRET source 3EG J1410–6147, using the Australia Telescope Compact Array and the Chandra X-ray Observatory. The observations encompass the supernova remnant (SNR) G312.4–0.4 and the two young pulsars PSRs J1412–6145 and J1413–6141. We derive a lower distance limit of 6 kpc to the SNR, although interpre...
متن کاملA New TeV Source in the Vicinity of Cygnus OB2
TeV Observations (during 1999, 2000 & 2001) of the Cygnus region using the HEGRA stereoscopic system of air Cherenkov telescopes have serendipitously revealed a signal positionally inside the core of the OB association Cygnus OB2, and ∼ 0.5◦ north of Cyg X-3. The source appears steady, has a post-trial significance of +4.6σ, indication for extension with radius 5.6′ at the ∼ 3σ level, and has a...
