Searching for Transient Neutrino Sources with IceCube in Real-Time

The IceCube neutrino observatory is a 1 km3 ^3 detector deployed deep in the Antarctic glacier. While IceCube recently discovered a diffuse astrophysical flux of high energy neutrinos, its sources are yet to be identified. With a field of view covering the whole sky and continuous data-taking, IceCube is capable of detecting transient sources when one or more high energy neutrinos arrive, and sending out an alert in real-time. Immediate triggering of follow-up observations in the optical, x-ray and gamma-ray bands will increase the discovery potential of astrophysical sources and potentially help to constrain phenomenological models of high energy neutrino and gamma-ray emission. This poster shows upcoming upgrades to the neutrino-triggered multi-messenger programs in IceCube, designed to identify both neutrinos clustered in space and time from potential transient sources, as well as the most energetic single neutrino candidates with the highest chance of being of astrophysical origin.
