Neutrino triggered high-energy gamma-ray follow-up with IceCube

摘要

We present the status of a program for the generation of online alerts issued by IceCube for gamma-rayfollow-up observations by Air Shower Cherenkov telescopes (e.g. MAGIC). To overcome the low probability ofsimultaneous observations of flares of objects with gamma-ray and neutrino telescopes a neutrino triggered follow-upscheme is developed. This mode of operation aims at increasing the availability of simultaneous multi-messenger datawhich can increase the discovery potential and constrain the phenomenological interpretation of the high energy emissionof selected source classes (e.g. blazars). This requires a fast and stable online analysis of potential neutrino signals. Wepresent the work on a significance based alert scheme for a list of phenomenologically selected sources. To monitor thedetector and the alert system reliability, monitoring systems have been implemented on different levels. We show datafrom the first weeks of running this system.
