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 کاملX-ray observations of unidentified H.E.S.S. γ-ray sources
Abstract. In a survey of the inner part of the Galaxy, performed with the H.E.S.S. Instrument (High energy stereoscopic system) in 2004 and 2005, a large number of new unidentified very high energy (VHE) γ-ray sources above an energy of 100 GeV was discovered. Often the γ-ray spectra in these sources reach energies of up to ∼ 10 TeV. These are the highest energy particles ever attributed to sin...
متن کاملTeV γ - Ray Observations of the Perseus Galaxy Cluster
We report on observations of the Perseus cluster of galaxies using the 10 m Whipple γ-ray telescope during the 2004-2005 observing season. We apply a two dimensional analysis technique to allow us to scrutinize the cluster for TeV emission. In this contribution we will first calculate flux upper limits on TeV γ-ray sources within the cluster. Second, we derive an upper limit on the extended clu...
متن کاملObservations of VHE γ-Ray Sources with the MAGIC Telescope
The MAGIC telescope with its 17m diameter mirror is today the largest operating single-dish Imaging Air Cherenkov Telescope (IACT). It is located on the Canary Island La Palma, at an altitude of 2200m above sea level, as part of the Roque de los Muchachos European Northern Observatory. The MAGIC telescope detects celestial very high energy γ-radiation in the energy band between about 50 GeV and...
متن کاملTHE POPULATION OF RADIO SOURCES IN THE FIELD OF THE UNIDENTIFIED γ-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 i...
