Completing the Picture: Neutrinos from 1ES 1959+650 — •Thomas Kintscher1 and Kai Krings2 for the IceCube collaboration — 1DESY (Zeuthen) — 2TU München
The IceCube neutrino observatory is a 1 km3 in-ice Cherenkov detector at the Geographic South Pole. While it has observed an astrophysical flux of neutrinos, individual sources have yet to be found.
The high-peaked BL Lac object 1ES 1959+650 is an intriguing candidate, as it exhibited an “orphan flare” in 2002: Such behaviour of a TeV gamma-ray flare without a simultaneous X-ray flare is hard to accommodate in leptonic SSC models, making this a potential site of hadronic acceleration and thus a prime source candidate for neutrinos.
A recent increase of activity in gamma-rays from this source between May and July of 2016 now prompts for a dedicated analysis of IceCube data, looking for neutrinos correlated with the flaring states. This talk will present the model-independent approaches looking only for an excess of neutrinos, as well as a complementary search for a timely correlation between the neutrinos and gamma-ray data.
