MAGIC upper limits on the GRB 090102 afterglow
MAGIC Collaboration, J. Aleksić, S. Ansoldi +160
Indications of a GeV component in the emission from GRBs are known since the EGRET observations during the 1990's and they have been confirmed by the data of the Fermi satellite. T…
MAGIC observations and multifrequency properties of the Flat Spectrum Radio Quasar 3C 279 in 2011
J. Aleksić, S. Ansoldi, L. A. Antonelli +168
We study the multifrequency emission and spectral properties of the quasar 3C 279. We observed 3C 279 in very high energy (VHE, E>100GeV) gamma rays, with the MAGIC telescopes duri…
Contemporaneous observations of the radio galaxy NGC 1275 from radio to very high energy gamma-rays
MAGIC Collaboration, J. Aleksić, S. Ansoldi +157
The radio galaxy NGC 1275, recently identified as a very high energy (VHE, >100 GeV) gamma-ray emitter by MAGIC, is one of the few non-blazar AGN detected in the VHE regime. In ord…
Search for TeV -ray emission from AE Aqr coincident with high optical and X-ray states with the MAGIC telescopes
R. Lopez-Coto, O. Blanch Bigas, J. Cortina +9
We report on observations of the nova-like cataclysmic variable AE Aqr performed by MAGIC. The observations were part of a quasi-simultaneous multi-wavelength campaign carried out…
The NectarCAM camera project
J-F. Glicenstein, M. Barcelo, J-A. Barrio +57
In the framework of the next generation of Cherenkov telescopes, the Cherenkov Telescope Array (CTA), NectarCAM is a camera designed for the medium size telescopes covering the cen…
An Analog Trigger System for Atmospheric Cherenkov Telescopes
M. Barcelo, J. A. Barrio, O. Blanch Bigas +6
Arrays of Cherenkov telescopes typically use multi-level trigger schemes to keep the rate of random triggers from the night sky background low. At a first stage, individual telesco…
Progress in Monte Carlo design and optimization of the Cherenkov Telescope Array
K. Bernlöhr, A. Barnacka, Y. Becherini +41
The Cherenkov Telescope Array (CTA) will be an instrument covering a wide energy range in very-high-energy (VHE) gamma rays. CTA will include several types of telescopes, in order…
Rapid and multi-band variability of the TeV-bright active nucleus of the galaxy IC 310
The MAGIC Collaboration, J. Aleksić, L. A. Antonelli +161
Context. The radio galaxy IC 310 has recently been identified as a gamma-ray emitter based on observations at GeV energies with Fermi-LAT and at very high energies (VHE, E>100GeV)…
Detection system for forward emitted photons at the Experimental Storage Ring at GSI
V. Hannen, D. Anielski, C. Geppert +10
A single photon counting system has been developed for efficient detection of forward emitted fluorescence photons at the Experimental Storage Ring (ESR) at GSI. The system employs…
Discovery of very high energy gamma-ray emission from the blazar 1ES 1727+502 with the MAGIC Telescopes
MAGIC Collaboration, J. Aleksić, L. A. Antonelli +155
Motivated by the Costamante & Ghisellini (2002) predictions we investigated if the blazar 1ES 1727+502 (z=0.055) is emitting very high energy (VHE, E>100 GeV) gamma rays. We observ…
