[NU059] Realtime neutrino alerts and follow-up in IceCube
Since the detection of a diffuse flux of high-energy astrophysical neutrinos in 2013 by the IceCube neutrino observatory, their origin so far has remained unknown. With no steady sources of neutrinos observed in IceCube data, neutrinos produced during transient astrophysical events are a viable alternative. Identification of an electromagnetic counterpart that is coincident in time and space would be strong evidence of a source of these neutrinos. To support these searches, IceCube has implemented a realtime search for likely astrophysical neutrino candidates that includes alerts to the community for rapid follow-up observations. This contribution will highlight the realtime analysis system, the current realtime alerts now being produced, and some preliminary results from the first alerts.
