Neutrino event IceCube-170922A ; gamma-ray blazar TXS 0506+056

Sažetak
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 e 290 tera–electron volts. Its arrival direction was consistent with the location of a known gamma-ray blazar, TXS 0506+056, observed to be in a flaring state. An extensive multiwavelength campaign followed, ranging from radio frequencies to g-rays. These observations characterize the variability and energetics of the blazar and include the detection of TXS 0506+056 in very-high-energy g-rays. This observation of a neutrino in spatial coincidence with a gamma-ray–emitting blazar during an active phase suggests that blazars may be a source of high-energy neutrinos.
