Biography:
He was born on February 7, 1940 in Kyiv City of Kyiv region of Ukrainian SSR.
In 1962 he graduated from the Department of Astronomy at the Faculty of Physics of the T. G. Shevchenko Kyiv Order of Lenin State University.
He worked at the Byurakan Astrophysical Observatory of the Academy of Sciences of the Armenian SSR, where he also graduated from the postgraduate study program under the supervision of acad. Ambartsumyana V.A.
In 1967 he defended his Ph.D. thesis in the Biurakan Astrophysical Observatory "Statistical Study of Non-Stability of Galactic Systems".
in 1981 he defended his doctoral dissertation "Dynamics and structure of double galaxies".
During 1967-1971 he worked at the Kyiv State University as an assistant and senior lecturer in the Department of General Astronomy. He read the courses "General astrophysics", "Star and extragalactic astronomy". He initiated the training of specialists in the University and research on extragalactic astronomy.
Since 1971 he has been working at the Special Astrophysical Observatory of the USSR Academy of Sciences (now the Russian Academy of Sciences) where he was a senior researcher in 1971-1973, deputy director of research in 1973-1975, head of department in 1973-1989, head of the laboratory 1989-2008, since 2008 he has been chief researcher.
During 1977-1992, he was a member and secretary of the Program Committee of the 6th Telescope of the Special Astrophysical Observatory. Prepared 12 candidates for physical and mathematical Science.
Since the mid-1990s in collaboration with D. I. Makarov is studying the distribution and motion of nearby galaxies at a distance of less than 10 Mpc, in the so-called Local Volume.
In 2010, he, together with Mitronova V.E., Karachentseva V.Yu., Melnyk O.V. created the "Catalog of isolated galaxies, selected from the review of 2MASS".
A study of the distribution of galaxies in the Local Supercluster, performed in 2010 in collaboration with D. I. Makarov, allowed to determine the average density of the substance of the prisoner inside the virtualized areas, Ωm=0.08. This value is about 3 times smaller than the global value obtained from the study of the microwave background of the Universe.
In 2011 he, together with Karachentseva V.E., Makarov D.I. and Melnyk O.V. created the "Catalog of close isolated galaxies in volume z<0.01".
Main directions of scientific activity: extragalactic astronomy and cosmology. Investigated morphological and physical characteristics of double, multiple and interacting galaxies; physical and dynamic properties of galaxy systems; spiral structure of galaxies and intergalactic absorption of light. Showing that the mass/luminosity ratio increases with the complexity of the system. Observations on the Hubble Space Telescope first determined the distance to 250 nearest galaxies. Having shown that the beam velocities and distances of galaxies within 10 Mpc are subject to universal Hubble dependence with chaotic motions of about 25 km/s, and the average density of baryon matter is about 2% of the critical density in the universe.
As one of the first observers on the 6-meter azimuth telescope, he measured velocities, determined masses and moments of rotation for more than 1,000 galaxies in binary systems, determined the nature of their orbital motions, and found evidence of active star formation under the influence of mutual tides.
He measured the red shifts and distances of up to 2000 thin spiral galaxies from the catalog he created, determined the amplitude and direction of the giant cosmic current, in which the galaxies around us participate.
Exploring the three-dimensional structure and kinematics of the Local Universe, I.D. Karachentsev and D.I. Makarov showed that less than half of the total amount of dark matter is in gravitationally bound systems.
He is author of the monograph, bigger 500 scientific publications, co-author of the textbook.
Member of editorial board of magazines "Astrophysics" and "Astrophysical bulletin".
Member of many scientific organizing committees of international symposia International Astronomical Union.
He is also a member of the international Eurasian astronomical conspiracy.
Awards: 1999 - Henri Chretien Award from the American Astronomical Society, 2004 - Bradyhin Prize of the Russian Academy of Sciences.
In 2010 he was awarded the title of "Honored Scientist of the Russian Federation" and in 2014 "Honorary Doctor of the Main Astronomical Observatory of Ukraine".
