Description
Previous detections of individual astrophysical sources of neutrinos are
limited to the Sun and the supernova 1987A, whereas the origins of the
diffuse flux of high-energy cosmic neutrinos remain unidentified. On 22
September 2017, we detected a high-energy neutrino, IceCube-170922A,
with an energy of ~290 tera-electron volts. Its arrival direction
was consistent with the location of a known γ-ray blazar, TXS
0506+056, observed to be in a flaring state. An extensive
multiwavelength campaign followed, ranging from radio frequencies to
γ-rays. These observations characterize the variability and
energetics of the blazar and include the detection of TXS 0506+056 in
very-high-energy γ-rays. This observation of a neutrino in spatial
coincidence with a γ-ray-emitting blazar during an active
phase suggests that blazars may be a source of high-energy neutrinos.
