Biography:
He was born on April 29, 1932 in Verbivka city of Ternopil region of Ukrainian SSR.
In 1954 he graduated from Ivan Franko Lviv State University where he entered in 1949.
Since 1954 he studied in graduate school, and in parallel began working in various positions at the Crimean Astrophysical Observatory. After graduating, he passed the school of prominent astrophysicists S. A. Kaplan and S. B. Pickelner. During 1954-1962, he worked on Mount Koshka, during 1962-2014, in the Nauchniy village.
In 1962 he defended his dissertation "Energy balance of free electrons and electron temperature in gas nebulae" at P. K. Sternberg State Astronomical Institute of M. V. Lomonosov Moscow State University.
He found a temperature gradienton the surface of the Lagoon Nebula.
He was the first to initiate research at the Crimean Astrophysical Observatory on active galactic nuclei and became the founder of a new scientific direction for the Crimean Astrophysical Observatory.
In 1964, he and E.A. Dibay began detailed spectral observations of Seyfert galaxies using a 125-centimeter reflector at the Crimean station of the P. K. Sternberg State Astronomical Institute. They proposed the term "broad emission line region" for galaxies with active nuclei.
E. A. Dibai, V. I. Pronik, K. K. Chuvaev and V. M. Lyutiy in the 70s of the XX century made a great contribution to the study of the central regions of the Seifert Galaxy in the optical range. E. A. Dibay and V. I. Pronik proposed an "empirical model of active nuclei" based on the analysis of their spectra and the assumption of photoionization of gas clouds by a continuous non-thermal continuum from the active nucleus.
He took part in a scientific expedition to the Pamirs. He worked on a business trip in Chile for about a year.
He died on February 26, 2016.
The main directions of his scientific work are astrophysics, the study of the structure of galaxies. He has become a leading expert in the study of the gaseous environment in various objects of the universe: in diffuse and planetary nebulae, in the remnants of supernovae, in the active nuclei of galaxies. He found a temperature gradient in the diffuse nebulae of the Galaxy. He is the author of almost 150 scientific papers.
V.I.Pronik discovered the non-isothermal nature of diffuse galactic nebulae and built the first structural model of the nuclei of active galaxies.
The research work of V. I .Pronik is harmoniously connected with the problems of astroinstrument making. According to his project and participation, a number of spectral devices were made for the largest 2.6-m telescope in Ukraine. A spectrograph built at the Crimean Astrophysical Observatory is working in the Canary Islands. He was one of the active participants in the ASTRON experiment, as a result of which the first ultraviolet telescope with a diameter of 0.8 m was launched into orbit in 1983. He participated in the design, manufacture, assembly and control of the optical system, as well as in observations. analysis of the obtained unique data of extragalactic systems. He is successfully working on the Spectrum-UV space project.
