Magic Observations of the Unidentified Γ-ray Source Tev
We observed the first known very high energy (VHE) γ-ray emitting unidentified source, TeV J2032+4130, for 94 hours with the MAGIC telescope. The source was detected with a significance of 5.6σ. The flux, position, and angular extension are compatible with the previous ones measured by the HEGRA telescope system five years ago. The integral flux amounts to (4.5±0.3stat±0.35sys)×10 −13 ph cm s a...
متن کاملDemystifying an unidentified EGRET source by VHE gamma-ray observations
In a novel approach in observational highenergy gamma-ray astronomy, observations carried out by imaging atmospheric Cherenkov telescopes provide necessary templates to pinpoint the nature of intriguing, yet unidentified EGRET gamma-ray sources. Using GeV-photons detected by CGRO EGRET and taking advantage of high spatial resolution images from H.E.S.S. observations, we were able to shed new li...
متن کاملVeritas Observations of Gamma-ray Bursts Detected by Swift
We present the results of 16 Swift-triggered Gamma-ray burst (GRB) follow-up observations taken with the Very Energetic Radiation Imaging Telescope Array System (VERITAS) telescope array from 2007 January to 2009 June. The median energy threshold and response time of these observations were 260 GeV and 320 s, respectively. Observations had an average duration of 90 minutes. Each burst is analyz...
متن کاملChandra Observation of the Unidentified TeV Gamma-Ray Source HESS J1303−631 in the Galactic Plane
The imaging atmospheric Cherenkov array H.E.S.S. recently discovered an extended source in the 0.4−10 TeV energy range, HESS J1303−631. We obtained a 5 ks observation with the ACIS-I array on the Chandra X-ray observatory that does not reveal an obvious compact or diffuse X-ray counterpart. Archival ROSAT images are also blank in this region. Although there are several radio pulsars within the ...
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...
