The international group of researchers, which includes the representative of the University of Nova Gorica, Dr. Gabrijela Zaharijas, announced the discovery of a high-energy particle, having specified the probable place of its origin. It is reported by the press service of the university.
“About 4 billion years ago, a black hole in the centre of an unknown distant galaxy created a stream of high-energy particles. An international group of researchers, including the scientist from the University of Nova Gorica, Dr. Gabrijela Zaharijas, announced the discovery of one of such particles–fragile neutrinos–and managed to determine its probable place of origin by using the NASA Fermi space telescope. This is the first time that we have received direct evidence of that astrophysical sources, the so-called Blazars or, more precisely, supermassive black holes located in their centres, produce high-energy neutrinos,” says the press release published by the University of Nova Gorica.
“The Fermi satellite recorded gamma radiation from a distant galaxy, in which the high-energy neutrinos were also detected,” says Paul Hertz, the Head of the Astrophysics Department at NASA headquarters in Washington. “This is another significant step forward in the rapidly developing field of observational astronomy after last year’s detection of gamma radiation by the Fermi satellite associated with the gravitational-wave signal phenomenon caused by the merger of two neutron stars.“
