Improving the performance of the single-dish Cherenkov telescope MAGIC through the use of signal timing

MAGIC Collaboration

The Cherenkov light flashes produced by Extensive Air Showers are very short in time. A high bandwidth and fast digitizing readout, therefore, can minimize the influence of the bac…

MAGIC upper limits to the VHE gamma-ray flux of 3C454.3 in high emission state

H. Anderhub, S. Vercellone, I. Donnarumma +2

We report upper limits to the very high energy flux (E>100 GeV) of the flat spectrum radio quasar 3C454.3 (z=0.859) derived by the Cherenkov telescope MAGIC during the high states…

Discovery of a very high energy gamma-ray signal from the 3C 66A/B region

MAGIC Collaboration, E. Aliu

The MAGIC telescope observed the region around the distant blazar 3C 66A for 54.2 h in 2007 August-December. The observations resulted in the discovery of a gamma-ray source at ene…

Observation of Pulsed Gamma-rays Above 25 GeV from the Crab Pulsar with MAGIC

The MAGIC Collaboration, E. Aliu

One fundamental question about pulsars concerns the mechanism of their pulsed electromagnetic emission. Measuring the high-end region of a pulsar's spectrum would shed light on thi…

First bounds on the high-energy emission from isolated Wolf-Rayet binary systems

MAGIC Collaboration, E. Aliu

High-energy gamma-ray emission is theoretically expected to arise in tight binary star systems (with high mass loss and high velocity winds), although the evidence of this relation…

Very-High-Energy Gamma Rays from a Distant Quasar: How Transparent Is the Universe?

MAGIC Collaboration, J. Albert

The atmospheric Cherenkov gamma-ray telescope MAGIC, designed for a low-energy threshold, has detected very-high-energy gamma rays from a giant flare of the distant Quasi-Stellar R…
