Description
Neutrino is considered as an ideal astronomical messenger thanks to not being deflected or absorbed by interstellar medium. Detection of neutrinos from distant high-energy cosmic accelerators has been a long-standing problem emerged in the last quarter of the 20-th century. And only in 2013 was the diffuse cosmic neutrino flux discovered by the 1 km3 -scale IceCube neutrino telescope at the South Pole. Nevertheless sources of cosmic neutrino remain unknown up to the present day. The Baikal-GVD neutrino telescope being built in the Lake Baikal is the largest detector of this kind in the Northern Hemisphere. Presently an instrumented volume of the detector reaches ~0.5 km3 which allows the telescope to start contributing to the cosmic neutrino origin quest. In this talk we give an overview of high-energy neutrino astronomy and discuss the status and main results of the Baikal-GVD experiment.
