MAGIC

1
MAGIC

• Cycle 1 of data taking from Mar 2005 to Apr 2006
• 1200 hours, with efficiency 80
• Close to design performance
• 1 new galactic source discovered, plus 3 to 6
  extragalactic
• MAGIC Catalog opened by the Astronomical
  Association
• 2 GRB observations during the primary burst
• Many cooperations (Integral, Suzaku, Swift, GCN,
  optical telescopes triggers sent received)
• Papers published or submitted for all positive
  signals, but 5 (Crab, Mkn501, 3 possible new
  sources)
• Threshold
• Detect significant signal above 40 GeV
• Publishing with a threshold of 70 GeV, and
  preliminary physics results at 50 GeV
• Cycle 2 started on May 2006
• Objectives on fundamental physics, DM, GRBs,
  cosmological constants

The second telescope

• Will allow improving the threshold (30 GeV?) and
  reaching HESS angular resolution and sensitivity
  at the TeV
• Goal to be ready end 2007, to make simultaneous
  observations with GLAST
• Mechanics finished in Dec 2005, in schedule
• Mirror production (new 1m2 technology tested on
  MAGIC 1) contract for the production of the raw
  blanks signed in June
• We are late by 4 months, but still possibility to
  be on time
