IceCube detects galaxy M77 as a cosmic neutrino source

Statistical clustering emerges for three positions of known objects. In particular, for the relatively nearby active galaxy NGC 1068 (M77), an excess of about 80 neutrino interactions is observed, corresponding to a global significance of 4.2 standard deviations. Since no highest-energy gamma rays are known from this galaxy so far, it is assumed that the neutrino radiation comes from the very dense, opaque central region around a massive black hole, which can now be probed via neutrinos.
