Grigory Vladimirovich Domogazki

Grigori Wladimirowitsch Domogazki , Russian Григорий Владимирович Домогацкий , English transcription Gregory Domogatsky or Domogatskii, (born January 15, 1941 ) is a Russian experimental astro-particle physicist.

Domogazki graduated from Lomonosov University in 1964 and then went to Lebedev Institute . In 1980 he completed his habilitation (Russian doctorate) on neutrino formation in stars during gravitational collapse (see Supernova ).

In the 1970s he was involved with Georgi Timofejewitsch Sazepin in building the Baksan neutrino telescope in the Caucasus. With Sazepin he suggested in 1965 that the gravitational collapse of stars could be observed via the neutrino signals. He later showed that the neutrinos released in the process also play a role in the formation of isotopes (Li 7, Be 8, B 11) in the collapsing star and that these processes play an important role in nucleosynthesis in the cosmos.

He is the spokesman for the neutrino experiment in Lake Baikal (NT-200) and since 1980 head of the laboratory for high-energy neutrino astrophysics at the Institute for Nuclear Research (INR) of the Russian Academy of Sciences. The Baikal telescope goes back to an idea by Moissei Alexandrowitsch Markow , is a German-Russian joint project and was first installed in 1993. 3.6 km from the shore, chains of around 200 optical modules (photomultiplier for Cherenkov radiation) attached to buoys and on the lake bed in the final stage of the NT-200 are installed at a depth of 1100 m. Lake Baikal has the advantage that it is particularly deep, has particularly clear water and the equipment can be serviced on the frozen lake in winter. The technology for underwater neutrino telescopes was developed here in the 1980s and in the American Dumand project (first tests from 1976 on the Pacific coast, but discontinued in 1995) and later also in the Mediterranean (Nestor, Antares) and in the Antarctic (Amanda and its successor IceCube in the ice). It is also used to search for WIMPs and dark matter candidates via the neutrino signals .

In 2006 he received the Markow Prize for the Baikal experiment with Christian Spiering . In 2014 he received the Bruno Pontecorvo Prize . He has been a corresponding member of the Russian Academy of Sciences since 2008 . He heads the Neutrino Physics Council of the Russian Academy of Sciences.
