Follow-up of Astrophysical Transients in Real Time with the IceCube Neutrino Observatory

Abstract: In multi-messenger astronomy, rapid investigation of interesting transients is imperative. As an observatory with a 4π steradian field of view, and ∼99% uptime, the IceCube Neutrino Observatory is a unique facility to follow up transients, as well as to provide valuable insights for other observatories and inform their observational decisions. Since 2016, IceCube has been using low-latency data to rapidly respond to interesting astrophysical events reported by the multi-messenger observational community. Here,… Show more

“…The growing number of cosmic neutrino alerts has triggered follow-up searches for coincident detection of electromagnetic radiation, see, e.g., Abbasi et al (2021c), Garrappa et al (2019), Acciari et al (2021). On 2019 October 1, the IceCube Collaboration reported the detection of a muon track neutrino of likely astrophysical origin, IC191001A.…”

“…Since 2016, the IceCube multimessenger program has grown from issuing Galactic supernova alerts [ 48 ] and common data analyses matching neutrinos with early LIGO/Virgo gravitational wave candidates to a steadily expanding set of automatic filters that selects in real time rare, very high energy neutrino events that are likely to be cosmic in origin. [ 49 ] Within less than a minute of stopping in the instrumented Antarctic ice, the arrival directions of the neutrinos are reconstructed and automatically sent to the Gamma‐ray Coordinate Network for potential follow‐up by astronomical telescopes.…”

“…It is predicted that astrophysical neutrinos are produced in the highest energy extragalactic sources such as the super-massive black holes at the centre of active galactic nuclei [46,47], the collapse of massive stars in gamma ray bursts [48,49], or in star burst galaxies [50]. Although some potential points sources have been identified and there is growing evidence for the blazar connection [51,52], the exact nature of astrophysical neutrino sources remain uncertain [53][54][55][56][57][58][59][60][61][62].…”
