“The era of multimessenger astrophysics is here,” said France Córdova (NSF Director)
IceCube Neutrino Observatory points out the evidence for the observation of the first known source of high-energy neutrinos and cosmic rays. A high energy neutrino detected by IceCube on September 22, 2017 ushered the scientist group to its source, a blazar designated by astronomers as TXS 0506+056.
Fermi Gamma-ray Space Telescope and Major Atmospheric Gamma Imaging Cherenkov Telescope (MAGIC) also detected a flare of high-energy gamma rays associated with TXS 0506+056, a convergence of observations that convincingly implicated the blazar as the most likely source.
