MAGIC upper limits on the very high energy emission from GRBs

J. Albert, E. Aliu, H. Anderhub +57

The fast repositioning system of the MAGIC Telescope has allowed during its first data cycle, between 2005 and the beginning of year 2006, observing nine different GRBs as possible…

Signal Reconstruction for the MAGIC Telescope

J. Albert

Until April 2007 the MAGIC telescope used a 300 MSamples/s FADC system to sample the shaped PMT signals produced by the captured Cherenkov photons of air showers. Different algorit…

Observation of very high energy gamma-rays from the AGN 1ES 2344+514 in a low emission state with the MAGIC telescope

J. Albert et al.

The MAGIC collaboration has observed very high energy gamma ray emission from the AGN 1ES 2344+514. A gamma-ray signal corresponding to an 11 sigma excess and an integral flux of (…

Break in the VHE spectrum of PG 1553+113: new upper limit on its redshift?

D. Mazin, F. Goebel

PG 1553+113 is a known BL Lac object, newly detected in the GeV-TeV energy range by H.E.S.S and MAGIC. The redshift of this source is unknown and a lower limit of was re…

First bounds on the very high energy gamma-ray emission from Arp 220

J. Albert et al.

Using the Major Atmospheric Gamma Imaging Cherenkov Telescope (MAGIC), we have observed the nearest ultra-luminous infrared galaxy Arp 220 for about 15 hours. No significant signal…
