Galactic Center searchesGalactic Center searches

at GC by HESS

– Match BH @ SGR A*

– Tail not NFW like

– Spectrum not DM like

at GC by MAGIC

– Consistent with HESS

– Higher threshold

– IFAE

Standard MW satellites

– Traditional opt. telescopes

– Close, large M/L

– Draco, UMi, …

New MW satellites– Discovered by SDSS

– Largest M/L

– Willman I, Segue I

– MAGIC (UCM-GAE, IAA), Others

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
