“…These quantities are sensitive to disturbances in the datacollection process (Aartsen et al 2017d). These disturbances are classified as either internal, such as interrupted connections to a segment of the detector, or external, such as interference from other experiments at the South Pole.…”

“…After application of these criteria, the event rate is reduced to 5 Hz, which is low enough to apply more sophisticated and time-consuming reconstruction algorithms (see Aartsen et al 2015b, for a more detailed description). Based on the results of these reconstructions, the most signal-like events are selected using a multivariate classifier (see Aartsen et al 2017d, for more details on the event selection and data transmission).…”

“…IceCube has several real-time follow-up programs which select events and generate alerts in different ways (Aartsen et al 2017d). The neutrino alert described in this paper was found by the optical follow-up program (see also Abbasi et al 2012b;Evans et al 2015;Aartsen et al 2015b) which searches for short transient neutrino sources and triggers optical telescopes as well as the Swift X-ray telescope.…”

“…In addition to the publicly announced high-energy neutrino alerts, IceCube has a real-time program that searches for multiple neutrinos from a similar direction (Abbasi et al 2012b;Aartsen et al 2017d). When two or more muon neutrino candidates are detected within 100 s of each other optical and X-ray observations can be triggered automatically Aartsen et al 2015b).…”

“…However, no timely follow-up observations were triggered and a transient counterpart could have gone unnoticed. Since mid-2016, such events are identified, reconstructed, and published within minutes (Aartsen et al 2017d) to allow quick follow-up observations (see Blaufuss 2016, as an example for the first published event).…”

On February 17 2016, the IceCube real-time neutrino search identified, for the first time, three muon neutrino candidates arriving within 100 s of one another, consistent with coming from the same point in the sky. Such a triplet is expected once every 13.7 years as a random coincidence of background events. However, considering the lifetime of the follow-up program the probability of detecting at least one triplet from atmospheric background is 32%. Follow-up observatories were notified in order to search for an electromagnetic counterpart. Observations were obtained by Swift's X-ray telescope, by ASAS-SN, LCO and MASTER at optical wavelengths, and by VERITAS in the very-high-energy gamma-ray regime. Moreover, the Swift BAT serendipitously observed the location 100 s after the first neutrino was detected, and data from the Fermi LAT and HAWC observatory were analyzed. We present details of the neutrino triplet and the follow-up observations. No likely electromagnetic counterpart was detected, and we discuss the implications of these constraints on candidate neutrino sources such as gamma-ray bursts, core-collapse supernovae and active galactic nucleus flares. This study illustrates the potential of and challenges for future follow-up campaigns.

High‐Energy Neutrinos from the Cosmos

The IceCube project transformed a cubic kilometer of transparent natural Antarctic ice into a Cherenkov detector. It discovered PeV‐energy neutrinos originating beyond our galaxy with an energy flux that is comparable to that of GeV‐energy gamma rays and EeV‐energy cosmic rays. These neutrinos provide the only unobstructed view of the cosmic accelerators that power the highest energy radiation reaching us from the universe. The results from IceCube's first decade of operations, foremost the measurement of the diffuse neutrino flux from the universe using multiple techniques is reviewed. The multimessenger data that identified the supermassive black hole TXS 0506+056 as a source of cosmic neutrinos is subsequently reviewed and attention is drawn to accumulating indications that cosmic neutrinos are associated with gamma‐ray‐obscured active galaxies, that is, the energy in gamma rays that accompanies cosmic neutrinos emerges at MeV energies, or below. Reaching beyond 10 PeV energy, cosmic neutrinos provide a natural beam to study neutrinos themselves.

The Chinese–French space mission SVOM (Space‐based multiband astronomical Variable Objects Monitor) is mainly designed to detect and localize γ‐ray burst (GRB) events. The satellite, to be launched in late 2021, will carry a set of γ‐ray, X‐ray, and optical imagers. Thanks to its pointing strategy, quick slew capability, and fast data connection to Earth, ground‐based observations with large telescopes will allow us to measure redshifts for an unprecedented number of GRBs. While the association of long GRBs with core‐collapse supernovae (SNe) is well established, short GRBs are most likely due to neutron star (NS)–NS or NS–BH (black hole) mergers and are thus expected to occur simultaneously with bursts of gravitational waves. We discuss here the overall science goals of the SVOM mission in the framework of the multiwavelength and multimessenger panorama of the next decade.
