Comment on the paper Neutrino lighthouse at Sagittarius A*: Interior of a black hole as the birthplace of cosmic rays and neutrinos

Abstract : Apparently a quarter of very-high-energy neutrinos detected so far at the IceCube [1, 2] come from the center of the Milky Way, i.e. the supermassive black hole in the center of our galaxy behaves as a neutrino (or antineutrino?) factory [3]. A few years ago [4, 5, 6] it was argued that if particles and antiparticles have gravitational charge of the opposite sign, the interior of a black hole must be the birthplace of cosmic rays including neutrinos; hence, generally speaking, each black hole must be a point-like source of antineutrinos. Now, we show that, in the case of the Milky Way's supermassive black hole, our theoretical predictions are compatible with the observed range (30 TeV to 2 PeV) of energies.
