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 to MJD (Sep’08-Jun’11) – 4 different analysis types: Agustín Sánchez Losa27-Jul

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

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) » PKS , , 3C454.3, , PKS , 3C279, PKS , PKS , PKS , PKS , J , , WComae, PKS , , 3C273, PKS , 0FGLJ , PKSB Blazars (TeV): HESS, MAGIC, VERITAS... (TeVcat, ATel, arXiv...) – Original list of 29 sources → Selected 3 sources (3 flares): » 1ES , PKS , M87 PWN (GeV): Fermi. – Orignial list of 3 sources → 3 sources (5 flares): » Crab, PMNJ2345, PMNJ2250 Agustín Sánchez Losa27-Jul

9 Flare Sample: PKS Agustín Sánchez Losa27-Jul

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 Jul-2011
