1ES1218+304 (z=0.182) Soft Energy Spectrum Preliminary
PG 1553 (z>0.25) Very Soft energy spectrum the attenuation by pair creation or nature of SSC mechanism
GRB observation by MAGIC Uniformity MAGIC GLAST Pulse Duration “short” “long” ~10sec GRB trigger Satellite to MAGIC ~20sec MAGIC slewing time
MAGIC made an observation in the period of the main prompt emission!! But we knew later z = 6.3.
MAGIC one and a half year results Source observations Galactic 4 sources are observed Extragalactic 6 sources are observed Distant sources show soft energy spectra The attenuation by e+- creation The nature of SSC mechanism The number of sources is increasing GRBs 9 fast follow-up observations are carried out 2 are in prompt phase among 9
