Mgr. Lukáš Fajt:
The next-generation neutrino telescope at Lake Baikal

Abstract:
The installation of the neutrino telescope Baikal-GVD started in 2015 and recently, more than half of its final sensitive volume, 0.4 km3, is already instrumented by 1440 light sensitive optical modules. Their only goal, in the darkness of approximate 1\,km depth of Lake Baikal, is the detection of Cherenkov light produced by the ultra relativistic secondary charged particles created in the interactions of high energy neutrinos. Neutrinos that are coming from unimaginable distances accelerated to the energies unreachable by the humankind in the processes on the edge of our understanding billions years ago.

In this talk, the brief description of the neutrino astronomy, of the neutrino telescope and of the high energy neutrino detection mechanism is going to be given. The presentation is going to be accompanied by the short videos from the winter expedition at the lake where the new parts of the detector are installed. In addition, the most recent results achieved in the data analysis are going to be presented.
