We present the results from a multiwavelength campaign on the TeV blazar 1ES 1959+650, performed in May, 2006. Data from the optical, UV, soft- and hard-X-ray and very high energy…
Detection of Very-High Energy Gamma-Rays from the BL Lac Object PG 1553+113 with the MAGIC Telescope
Robert Wagner, Daniela Dorner, Masaaki Hayashida +5
The MAGIC telescope has observed very-high energy gamma-ray emission from the BL Lac object PG 1553+113 in 2005 and 2006 at an overall significance is 8.8 sigma. The light curve sh…
Upper limit for gamma-ray emission above 140 GeV from the dwarf spheroidal galaxy Draco
MAGIC Collaboration, J. Albert
The nearby dwarf spheroidal galaxy Draco with its high mass to light ratio is one of the most auspicious targets for indirect dark matter searches. Annihilation of hypothetical DM…

Very High Energy Gamma-ray Radiation from the Stellar-mass Black Hole Cygnus X-1
MAGIC Collaboration, J. Albert
We report on the results from the observations in very high energy band (VHE, E_gamma > 100 GeV) of the black hole X-ray binary (BHXB) Cygnus X-1. The observations were performed w…
Discovery of VHE Gamma Radiation from IC443 with the MAGIC Telescope
MAGIC Collaboration
We report the detection of a new source of very high energy (VHE, E_gamma >= 100GeV) gamma-ray emission located close to the Galactic Plane, MAGIC J0616+225, which is spatially coi…
Systematic search for VHE gamma-ray emission from X-ray bright high-frequency BL Lac objects
M. Meyer
All but three (M87, BL Lac and 3C 279) extragalactic sources detected so far at very high energy (VHE) gamma-rays belong to the class of high-frequency peaked BL Lac (HBL) objects.…
Observation of VHE gamma-rays from Cassiopeia A with the MAGIC telescope
J. Albert
We searched for very high energy (VHE) gamma-ray emission from the supernova remnant Cassiopeia A. The shell-type supernova remnant Cassiopeia A was observed with the 17 meter MAGI…
VHE Gamma-Ray Observation of the Crab Nebula and its Pulsar with the MAGIC telescope
MAGIC Collaboration, J. Albert
We report about very high energy (VHE) gamma-ray observations of the Crab Nebula with the MAGIC telescope. The gamma-ray flux from the nebula was measured between 60 GeV and 9 TeV.…
