Search of high energy neutrino flares from Active Galactic Nuclei with the IceCube detector — •Angel Humberto Cruz Silva1, Dariusz Gora1,2, and Elisa Bernardini1 — 1DESY, Platanenallee 6, D 15738 Zeuthen, Germany — 2Institute of Nuclear Physics PAN, ul. Radzikowskiego 152,31-342 Cracow, Poland
Active Galactic Nuclei (AGN) are among the best candidates for sources of high energy cosmic rays. One of their properties is the extreme variability in their electromagnetic emission at different wavelengths with flare durations ranging from minutes, in some cases, to several weeks. This photon flares may be correlated with neutrinos emitted from the same source if protons are also accelerated in the AGN relativistic jet. Here we present a new statistical test method to look for neutrino flares from selected AGNs. The method takes into account a list of possible neutrino sources from different categories (FSRQs and BL-Lacs ) in a so called stacking approach. The performance and results of the method using IceCube data in its 79 string configuration are presented.
