Biography:
He was born on March 16, 1957 in the Bila village of Ternopil region of the Ukrainian SSR.
In 1979 he graduated from Ivan Franko Lviv State University.
Since 1988 to 1991 he studied at the graduate school of the P. M. Lebedev Astro-Space Center of the Physical Institute of the RSFSR Academy of Sciences.
In 1991 he defended his dissertation on "Modeling of large-scale flows of matter in the universe and the spectra of primary perturbations".
In 2007 he defended his doctoral dissertation at the Ivan Franko Lviv National University "Large-scale structure and parameters of the cosmological model of the observed universe" in the specialty "astrophysics, radio astronomy".
He works at the Astronomical Observatory of Ivan Franko Lviv National University as a chief researcher (head) of the Department of Relativistic Astrophysics and Cosmology at the Department of Stellar and Galaxy Physics, as well as at the Department of Astrophysics.
In addition, since 2002 he has been the head of the Astronomical Observatory of the Ivan Franko Lviv National University.
He is the Vice President of the Ukrainian Astronomical Association for the Teaching of Astronomy at the Higher School. He was elected to the UAA Board in 2009.
He also manages the scientific work of students and pupils of the Small Academy of Sciences, actively promotes Ukrainian science, a contributor to the scientific and methodological journal "Pedagogical Thought".
In 2014, he won the State Prize of Ukraine in Science and Technology for his work "Structure and Evolution of the Universe on Galactic and Cosmological Scales, Hidden Mass and Dark Energy: Theoretical Models and Observational Results" among co-authors.
In the 1980s, together with V. M. Lukash, he proposed and built a model of the Great Attractor as a large-scale peak in the density of dark space matter, which successfully explained the coherent motion of galaxies in the vicinity of the Virgo cluster relative to the relic radiation field.
The coherent convergent flow of galaxies to the center at a distance of ˜50h-1 Mpc to our Galaxy in the direction of the Hydra-Centaur constellation, discovered in the late 1980s by astrophysicist observers, proved to be a test for many cosmological models. and the scenario of the formation of the Large-Scale Structure of the Universe. He, together with V. M. Lukash and B. I. Gnatik, were among the first to propose to explain this phenomenon by the high-amplitude peak of large-scale heterogeneity in the spatial distribution of galaxies.
The main areas of research relate to the formation of a large-scale structure of the universe and its elements, the anisotropy of the temperature of relic radiation, the definition of cosmological pyrimeters and limitations on the model based on the observed data of the observed cosmos. He teaches special courses in cosmology and physics of galaxies. Together with V. O. Pelekh in 1983 he began scientific work on the analysis of the development of cosmological perturbations of density and velocity of matter.
The scientist is a member of the International Astronomical Union, European Astronomical Society. Collaborates with scientists from Russia, Italy, Germany and Switzerland.
He is a member of the Shevchenko Lviv Scientific Society.
