MAGIC Observations of PG 1553+113 during a Multiwavelength Campaign in July 2006

MAGIC Collaboration, Albert

The active galactic nucleus PG 1553+113 was observed by the MAGIC telescope in July 2006 during a multiwavelength campaign, in which telescopes in the optical, X-ray, and very high…

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…

Dark Matter signals from Draco and Willman 1: Prospects for MAGIC II and CTA

Torsten Bringmann, Michele Doro, Mattia Fornasa

The next generation of ground-based Imaging Air Cherenkov Telescopes (IACTs) will play an important role in indirect dark matter searches. In this article, we consider two particul…

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…

Very High Energy Gamma-Ray Observations of a Strong Flaring Activity in M87 in 2008 February

MAGIC Collaboration, J. Albert

M87 is the only known non blazar radio galaxy to emit very high energy (VHE) gamma-rays. During a monitoring program of M87, a rapid flare in VHE gamma-rays was detected by the MAG…

A novel background reduction strategy for high level triggers and processing in gamma-ray Cherenkov detectors

G. Cabras, A. De Angelis, B. De Lotto +17

Gamma ray astronomy is now at the leading edge for studies related both to fundamental physics and astrophysics. The sensitivity of gamma detectors is limited by the huge amount of…

MAGIC observations of the unidentified TeV gamma-ray source TeV J2032+4130

J. Albert

We observed the first known very high energy (VHE) gamma-ray emitting unidentified source, TeV J2032+4130, for 94 hours with the MAGIC telescope. The source was detected with a sig…
