  3. 4 years in orbit – June 11 2012 over 1.37 billion LAT events to the FSSC 1949 transients from GBM (939 GRB) 199 LAT collaboration papers (Cat I and Cat II) - been cited nearly 10,000 times 800 refereed papers with new Fermi results or using/interpreting Fermi results and issued over 30 press/web releases. D. Bastieri - INFN Gruppo II

  4. Fermi observatory status • No performance degradation • 0.06% TKR channels disabled (880k total) • TKR noise occupancy better than spec • 1 CAL crystal (out of 1536) with 1 (out of 4) readouts disabled • Smooth operations • < 1% downtime (+ ~15% in SAA) • All photon data are public • 680M photons so far Cumulative LAT Trigger counts D. Bastieri - INFN Gruppo II

  5. Fermi mission status • NASA 2012 Senior Review recommended extended operations • http://science.nasa.gov/astrophysics/2012-senior-review/ • NASA HQ will extend the mission to at least 2016 approved minimum  goal D. Bastieri - INFN Gruppo II

  6. Fermi in public • Maintaining public data and analysis tools is worth the effort • “Prize-winning” science (2011 AAS HEAD Rossi Prize, 2012 APS Panofsky Prize) • Effective outreach program (www.nasa.gov/fermi/ + app Fermi Sky) Collaboration papers D. Bastieri - INFN Gruppo II

  7. Supporting science with event level analysis • Current: completing extensive validation and study of systematic uncertainties • Next generation: redesigning event reconstruction and background rejection to enhance science potential • new TKR recon  Tree vs multiple tracks recon, independent from CAL recon  better Point Spread Function • new CAL recon  clustering, extend to 2 TeV • new ACD recon  improved and more flexible pointing to TKR and CAL, background rejection • Pile-up events tagging (TKR, CAL, ACD)  ghost removal • New background rejection  multiple classes of events to serve different science goals D. Bastieri - INFN Gruppo II

  8. Cosmic Ray Highlights PRL108 (2012) PRL102 (2009) - PRD 82 (2010) • …. and prospects • CRE spectrum up to 2 TeV • Proton isotropy • proton spectrum upturn at ~300 GeV measured by PAMELA with g-rays from the Earth D. Bastieri - INFN Gruppo II

  9. Super Novae Remnants Status arXiv:1201.0988 • …. and prospects • measure how CR acceleration depends on age and environment • disentangle emission mechanisms in dense media and possibly for young SNRs by isolating CR proton p0 emission from leptonic features D. Bastieri - INFN Gruppo II

  10. Crab Nebula flaring again! D. Bastieri - INFN Gruppo II

  11. Gigantic flare from the Crab Nebula A. Abdo et al., Science 331, 739 (2011). From 30 to 100 times brighter than usual. Detected in radio but not detectedby Chandra, even if during the (second) big flare it was pointing the Crab D. Bastieri - INFN Gruppo II

  12. Dark Matter Searches Status • Multiple targets and search strategies • Satellites (ApJ 747, 2012) • Lines (PRL 104, 2010) • IGRB (JCAP 04, 2010) • Galaxy clusters (JCAP 05, 2010) • Neutron stars (JCAP 12, 2012) • CREs (PRL 102, 2009, PRD82, 2010) • Halo • Dwarf galaxies (PRL 107, 2011) • g-ray anisotropies (arXiv:1202.2856) PRL107 (2011) • …. and prospects • detect/constrain WIMPs annihilation/decay up to several hundred GeV, • Strengthen multi-wavelength studies for detailed modeling of the Galactic center to assess claims of a dark matter signature D. Bastieri - INFN Gruppo II

  13. Solar and terrestrial physics status • …. and prospects • characterize solar flares during solar maximum and the declining phase of the solar cycle • study geographically, seasonal, and land/ocean differences in Terrestrial g-ray Flashes and their initiating storm systems APOD 3-15-2012 D. Bastieri - INFN Gruppo II
