Gamma astrophysics in the 50 GeV – 50 TeV domain
• Great results from Cherenkov telescopes (IACTs): number of VHE sources increased by more than one order of magnitude in 3 years
• Another factor of 3 expected with MAGIC2, HESS2– And crucial improvement in resolution
• Subjects of fundamental physics become accessible, e.g.– Lorentz violation– Dark matter– Transparency of the Universe (related to M, )
• Another order of magnitude can be gained with CTA– And more: room for new ideas…

• IACT results:– From 3 VHE
gamma sources in 2003, we went to ~40 in 2007
– ~100 is expected with MAGIC2, HESS2, synergy with GLAST
• HESS much more successful on galactic sources, MAGIC a bit more successful in extragalactic
from several communitiesastronomy & astrophysicsparticle physicsnuclear physics
about 250-300 scientists workingcurrently in the field will bedirectly involved,user community significantly larger

CTA - conclusions
• A 100-150 MEUR FP7 project possibly going to be posted in May 2007– Italy (INFN+INAF) weights ~ 10-15%
• Mirror technology, advanced electronics, R&D for new telescope design?
