A breakthrough on Multimessenger Astrophysics!


“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.
