Search for high-energy neutrino sources from the direction of IceCube alert events

Research output: Contribution to journalConference articlepeer-review


We use IceCube's high-statistics, neutrino-induced, through-going muon samples to search for astrophysical neutrino sources. Specifically, we analyze the arrival directions of IceCube's highest energy neutrinos. These high-energy events allow for a good angular reconstruction of their origin. Additionally, they have a high probability to come from an astrophysical source. On average, 8 neutrino events that satisfy these selection criteria are detected per year. Using these neutrino events as a source catalog, we present a search for the production sites of cosmic neutrinos. In this contribution we explore a time-dependent analysis, and present preliminary 3σ discovery potential fluences of ≈ 2.7 · 10−2GeV/cm2. We construct the fluences using expectation maximization.
