  1. 1stMultiDarkWorkshop UCM-GAE in MultiDark: Indirect searches for DM with the MAGIC Telescopes Juan Abel Barrio Universidad Complutense de Madrid, January 2010

  2. Contents • UCM-GAE • Activities: Dark Matter • IACT DM searches: MAGIC results • Prospects ?

  3. The group • History: • High Energy Physics: DELPHI @ LEP (85 – 95) • Astroparticle Physics: HEGRA, MAGIC, CTA (87 – 27?) • Members: • 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

  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: • Pulsars & AGNs • Dark matter: dSphs & Fermi “dark” sources • CTA: • Physics & data pipeline • Low energy telescopes: trigger & solid state photosensors • Site selection: Tenerife for Northern site

  7. DM indirect searches Astrophysics • Astrophysical factor • MAGIC 2007 • Draco • Cusp:  ~ 1 • Candidates • High M/L, distance vs. ρDM • Core:  ~ 0 • Milky Way Galactic Center • Milky Way dSph satellites • Globular Clusters • Nearby galaxies • Clusters of galaxies • Space missions“dark” sources

  8. Galactic Center searches • gat GC by HESS • Match BH @ SGR A* • Tail not NFW like • Spectrum not DM like • Boost factors ~ 102 • gat GC by MAGIC 20 TeV Neutralino 20 TeV KK particle • Consistent with HESS • Higher threshold • IFAE

  9. MW Satellitesearches • Standard MW satellites • Traditional opt. telescopes • Close, large M/L • Willman 1 • MAGIC 2008 • MAGIC 2007 • Draco • Draco • Draco, UMi, … • MAGIC (IAA), Others • New MW satellites • Discovered by SDSS • Largest M/L • Internal Bremmstrahlung • Willman I, Segue I • MAGIC (UCM-GAE, IAA), Others

  10. Otherobjectssearches • Galaxy Clusters • Perseus • MAGIC 2009 • Far / huge mass, large M/L • Perseus, Coma • MAGIC (IAA), HESS • Local Galaxies / Glob. Cl. • Close, cuspy, large M/L • VERITAS • M5, M32, M33  U.L.

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

  12. CTA Prospects • Smith (VERITAS) 2009

  13. Conclusions • UCM-GAE • Currently involved in MAGIC DM seaches • Expertise in handling Fermi data required / ¿possible? • Midterm manpower required to continue DM  MAGIC • 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

  14. Clusters of Galaxies searches • Sanchez-Conde 2008 • Perseus
