Space mission dark sourcesSpace mission dark sources Reason
– Substructures / IMBH “Dark” (non-associated) sources
– Satellites find hard/“dark” sources
– IACTs find cutoff
Strategy
– Fermi TeV candidates in EMS
1st try
– Recently variable (priv. comm. Emax< 30 GeV ) Rejected
2004
– UCM-GAE (Nieto & Mirabal) Single candidate

ConclusionsConclusions
UCM-GAE
IACT DM searches:
– No signal from Galactic Center
– No signal from MW Satellites or GC
– Current last chance: space missions IACTs
– CTA will have a chance
– Currently involved in MAGIC DM seaches
– Expertise in handling Fermi data required / ¿possible?
– Midterm manpower required to continue DM MAGIC
