Baikal neutrino telescope detects signal from radio blazar

(ORDO NEWS) — Neutrino telescopes at Lake Baikal and at the South Pole have detected the formation of neutrinos after the explosion of the radio blazar.

The appearance of neutrinos was recorded by the Ice Cube neutrino telescopes at the South Pole and the Baikal-GVD at Lake Baikal. In this case, the birth of a neutrino was recorded on a radio blazer, which emitted gamma radiation.

The radio bazar under consideration is called PKS 0735 + 17. The telescope at the South Pole recorded the first flare and estimated the release of energy at 172 TeV, and four hours later, the telescope on Lake Baikal recorded neutrinos with an energy of 43 TeV.

For the first time, two neutrino telescopes detected neutrinos from one source.

On December 14, scientists at the Ice Cube Neutrino Observatory identified an astrophysical neutrino candidate track with an energy estimate of about 172 TeV and, in accordance with the direction of arrival of this particle, determined that it could have originated on the PKS 0735+ radio observatory. 17. Four hours later, neutrinos with an energy estimate of 43 TeV from the same radio blazar were registered by the Baikal Neutrino Telescope.

The deep-sea neutrino telescope on Lake Baikal was launched in March this year. It has been under construction since 2015 by the international collaboration BAIKAL-GVD. The co-executors of the project were the Institute for Nuclear Research of the Russian Academy of Sciences, Irkutsk State University, Nizhny Novgorod Technical University.

The project involves the Institute of Experimental and Applied Physics of the Czech Technical University, the Faculty of Mathematics, Physics and Informatics of the University of Comenius (Slovakia), Ecologies Gumby (Germany), the Institute of Nuclear Physics of the Polish Academy of Sciences (Poland).
