Blazars have been proposed as efficient particle accelerators and promising neutrino sources long before the discovery of astrophysical high-energy neutrinos. The recent report by the IceCube Collaboration of a $\sim 3.5\sigma$ excess of $13\pm5$ neutrino events in the direction of the blazar TXS 0506+056 during a six month-long period in 2014-2015 as well as the detection of a single high-energy neutrino, IceCube-170922A, during a major gamma-ray flare from the same blazar in 2017, have… Expand
