(ANSA) – L’Aquila, April 20 – Russian physicist Veniamin Sergeevich Berezinsky, one of the founders of astroparticle physics, died at L’Aquila on the eve of his 89th birthday. This was announced by the scientific community at the Gran Sasso Science Institute (Gssi), where he was a teacher and researcher. “His research on the production of so-called neutrinos of cosmic origin – which is mentioned on the Gssi website – began in the 1960s. In particular, the article he wrote jointly with Georgy Zatsepin was a pioneer in the study of this phenomenon and a point of reference for all those who in the following years dealt with it High-energy neutrinos. His scientific activity has ranged from the origins of cosmic rays to supersymmetry, and from topological defects to cosmology.”
Among his ideas is the possibility of neutrino sources around black holes located at the center of active galaxies completely obscured in the gamma-ray band.
This idea found startling confirmation last year, when the ‘IceCube’ experiment, an astrophysical neutrino observatory buried in the Antarctic ice, detected neutrinos from the region around the supermassive black hole at the center of a veiled galaxy, NGC 1068.
Berezinsky, Venya of friends, contributed to the birth of the specialized journal Astroparticle Physics, and during his long career he has received many international awards. Among the most important are the 1991 Humboldt International Award, the 2007 Ouselay Medal, and the 2017 Enrico Fermi Award (ANSA).
