  1. Flare Analysis Summary of the present status AgustínSánchezLosa 27-Jul-2011

  2. Flare Analysis • Light curve denoising algorithm established: • Method of Scargle’s likelihood adapted to 2CP and with fixed Scargle’s prior (as presented in Moscow) • Flare periods (time PDFs, thresholds, etc) determined by the type of analysis • Analysis plan established: • Period interval fixed: 1000 days from 54710 to 55710 MJD (Sep’08-Jun’11) • 4 different analysis types: 27-Jul-2011 AgustínSánchezLosa

  3. Flare Analysis • Analysis types: • Individual flare analysis: • Only very significant flares • Low post-trial factor (proportional to the total number of flares) • Low number of events for discovery • 3 categories: • Blazars (GeV): Fermi, SWIFT,... • Blazars (TeV): HESS, MAGIC, VERITAS... • PWN (GeV): Fermi, SWIFT,... • Cumulative flare analysis: • Source by source • Post-trial factor equal to the number of studied sources • Selection of an adequate threshold • 1 category: • Blazars (GeV): Fermi, SWIFT,... • Untriggered analysis: search of clusters in time-space • Scanning analysis: event by event 27-Jul-2011 AgustínSánchezLosa

  4. Analysis status • Individual flare analysis: • Only very significant flares between [54710,55710] MJD • 3 categories: • Blazars (GeV): Fermi. • Original list of 23 sources → Selected 19 sources (43 flares) • PKS1502+106, 1510-089, 3C454.3, 0235+164, PKS0454-234, 3C279, PKS2155-304, PKS0537-441, PKS0727-11, PKS0805-07, J1057-6027, 0208-512, WComae, PKS1329-049, 1730-130, 3C273, PKS1424-41, 0FGLJ0910.2-5044, PKSB1222+216 • Blazars (TeV): HESS, MAGIC, VERITAS... (TeVcat, ATel, arXiv...) • Original list of 29 sources → Selected 3 sources (3 flares): • 1ES1218+304, PKS1222+21, M87 • PWN (GeV): Fermi. • Orignial list of 3 sources → 3 sources (5 flares): • Crab, PMNJ2345, PMNJ2250 27-Jul-2011 AgustínSánchezLosa

  7. Flare Sample: PKS1421-41 Manual Threshold Flares A Big Fluence Flare 27-Jul-2011 AgustínSánchezLosa

  8. Flare Sample: PKS1421-41 27-Jul-2011 AgustínSánchezLosa

  9. Flare Sample: PKS1421-41 27-Jul-2011 AgustínSánchezLosa

  10. To Do List • Debug the “flare’s tail smooth selection” algorithm and any other minor thing • Implement a threshold criteria based in the fluence of a box, not in the flux intensity • Once the flares are manually fixed and chosen start analyzing 27-Jul-2011 AgustínSánchezLosa
