But we knew later z = 6.3 Summary MAGIC Sources We have seen ~15 sources including several new sources Micro-Quasars are playing an important role as a source of galactic cosmic rays New 100GeV HBLs show steep spectra The attenuation by e+- creation The nature of SSC mechanism GRB observations 2 among 9 observations were done in prompt phase Eventually MAGIC may see VHE gammas from GRBs Second telescope MAGIC-II is under the construction in La Palma Next year we will start stereo observation 2 times better sensitivity number of sources may increase ~50 HESS and MAGIC people are planning CTA after HESS and MAGIC experiment 10 times better sensitivity than HESS and MAGIC 1000 VHE sources in norhtern and southern hemisphere March 2006 By W.Hofmann ∝Ntel 50hrs ∝Area Background Limited Signal Limited Kifune’s Plot (my optimistic expectation) GLAST AGILE ~3000 sources by GLAST, AGILE ~1000 sources by CTA
