The IceCube neutrino observatory is a 1 km 3 detector deployed in the ice at the South Pole. While it has observed an astrophysical flux of neutrinos, individual sources have yet to be identified and the high-peaked BL Lac object 1ES 1959+650 is an intriguing candidate. It exhibited an "orphan flare" in 2002: a TeV gamma ray flare without a simultaneous X-ray flare, behavior that is hard to accommodate in leptonic synchrotron self-compton models. This suggests that it is a potential site of hadronic acceleration and thus a prime source candidate for neutrinos. A recently observed increase in gamma ray activity from 1ES 1959+650 between May and July of 2016 has provided a new opportunity, prompting a dedicated search in IceCube data for neutrinos correlated with the flaring states during this period. We present results based on two model-independent approaches which look only for an excess of neutrinos from the source, as well as a more targeted search for a direct time correlation between neutrino events observed by IceCube and gamma ray emission observed with the FACT and MAGIC telescopes.

“…First attempts were made with the Neutrino Target of Opportunity and Gamma-ray Follow-Up programs, involving IceCube, MAGIC and VERITAS [166,167]. Also searches for persistent gamma-ray emitters in the error box of individual high-energy neutrinos [168][169][170] were performed.…”

We outline the science motivation for SGSO, the Southern Gamma-Ray Survey Observatory. SGSO will be a next-generation wide field-of-view gamma-ray survey instrument, sensitive to gamma-rays in the energy range from 100 GeV to hundreds of TeV. Its science topics include unveiling galactic and extragalactic particle accelerators, monitoring the transient sky at very high energies, probing particle physics beyond the Standard Model, and the characterization of the cosmic ray flux. SGSO will consist of an air shower detector array, located in South America. Due to its location and large field of view, SGSO will be complementary to other current and planned gamma-ray observatories such as HAWC, LHAASO, and CTA.

“…For several years, alerts have been sent out to optical, gamma-ray, and X-ray telescopes [13], which has led to a number of interesting results [14,15,16,17,18] as well as fostering a rich collaboration between electromagnetic and neutrino observatories. These long-running follow-up programs are supplemented by new neutrino selections that target single events deemed likely to be of astrophys-ical origin in the IceCube realtime alert system.…”

Although high-energy astrophysical neutrinos were discovered in 2013, their origin is still unknown. Aiming for the identification of an electromagnetic counterpart of a rapidly fading source, we have implemented a realtime analysis framework for the IceCube neutrino observatory. Several analyses selecting neutrinos of astrophysical origin are now operating in realtime at the detector site in Antarctica and are producing alerts for the community to enable rapid follow-up observations. The goal of these observations is to locate the astrophysical objects responsible for these neutrino signals. This paper highlights the infrastructure in place both at the South Pole site and at IceCube facilities in the north that have enabled this fast follow-up program to be implemented. Additionally, this paper presents the first realtime analyses to be activated within this framework, highlights their sensitivities to astrophysical neutrinos and background event rates, and presents an outlook for future discoveries.
