Description
On February 13, 2023, the KM3NeT detector, a soon-to-be cubic-kilometer neutrino telescope in the Mediterranean Sea, observed the highest-energy (~200 PeV) neutrino detected to date, designated KM3-230213A. This measurement marks an important milestone for astroparticle physics, and its origins could provide insight into the most extreme processes in the Universe. The IceCube Neutrino Observatory is a cubic-kilometer in-ice neutrino detector located at the geographic South Pole. Despite having an order-of-magnitude longer livetime and an order-of-magnitude greater effective area than KM3NeT, IceCube's highest-energy neutrinos are approximately 10 PeV. At the declination of KM3-230213A, IceCube is more sensitive than KM3NeT to neutrinos at energies from 1 TeV to 1 EeV. I will present results from three analyses aimed at identifying potential steady or transient neutrino sources in the direction of KM3-230213A’s using IceCube data.
