Blazars are active galactic nuclei that have their relativistic particle jet pointing towards Earth and have been observed e.g. by the Fermi-LAT instrument to emit gamma rays to very high energies. They are also candidates for the yet-unknown accelerators of ultra-high energy cosmic rays. In such a case, their gamma-ray emission might be associated with neutrinos produced by hadronic interactions in the jet. Correlating the gamma-rays' direction, magnitude and variability with the direction, energy and time of neutrinos detected by IceCube, a cubic-kilometre neutrino telescope at the South Pole could therefore reveal the origin of cosmic rays. I will describe this method and give an outlook on current developments.
