Juan Abel Barrio, GAE-UCM, January st MultiDark Workshop, Univ. Autónoma de Madrid MAGIC –3 staff professors: V. Fonseca, J.L. Contreras, J.A. Barrio –1 Ramón y Cajal: N. Mirabal –4 PhD students: I. Oya, D. Nieto, S. Pardo, R. García –2 electronic engineers: L.A. Tejedor, J.L. Lemus Members: 3 The group History: –High Energy Physics: LEP (85 – 95) –Astroparticle Physics: HEGRA, MAGIC, CTA (87 – 27?)

Juan Abel Barrio, GAE-UCM, January st MultiDark Workshop, Univ. Autónoma de Madrid MAGIC 4 Group activities MAGIC: –Data pipeline: Onsite analysis –Central Pixel of M-I for optical/gamma observation –M-I readout upgrade (along with IFAE) –Physics: CTA: –Physics & data pipeline –Low energy telescopes: trigger & solid state photosensors –Site selection: Tenerife for Northern site  Pulsars & AGNs  Dark matter: dSphs & Fermi “dark” sources

Juan Abel Barrio, GAE-UCM, January st MultiDark Workshop, Univ. Autónoma de Madrid MAGIC 8 Galactic Center searches  at GC by HESS –Match SGR A* –Tail not NFW like –Spectrum not DM like  at GC by MAGIC –Consistent with HESS –Higher threshold –IFAE 20 TeV Neutralino 20 TeV KK particle –Boost factors ~ 10 2

Juan Abel Barrio, GAE-UCM, January st MultiDark Workshop, Univ. Autónoma de Madrid MAGIC 11 Space mission dark sources Reason –Substructures / IMBH  “Dark” (non-associated) sources –Satellites find hard/“dark” sources –IACTs find cutoff Strategy –Fermi TeV candidates in EMS 1 st try –Recently variable (priv. comm. E max < 30 GeV )  Rejected 2004 –UCM-GAE (Nieto & Mirabal)  Single candidate EMSXX

Juan Abel Barrio, GAE-UCM, January st MultiDark Workshop, Univ. Autónoma de Madrid MAGIC 13 Conclusions 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
