1 Flare Analysis Summary of the present status Agustín Sánchez Losa27-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: Agustín Sánchez Losa27-Jul-2011 2

3 Flare Analysis Analysis types: 1.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,... 2.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,... 3.Untriggered analysis: search of clusters in time-space 4.Scanning analysis: event by event Agustín Sánchez Losa27-Jul-2011 3

4 Analysis status 1.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 Agustín Sánchez Losa27-Jul-2011 4

9 Flare Sample: PKS1421-41 Agustín Sánchez Losa27-Jul-2011 9

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 Agustín Sánchez Losa 10 27-Jul-2011
