Biography:
He was born on February 26, 1952, in Stalino city of the Ukrainian SSR, now the Donetsk city of Donetsk region of Ukraine.
After completing his studies at the physical faculty of the T. G. Shevchenko Kyiv Order of Lenin State University in 1974, in the field of astronomy, he worked for about 3 years at the Department of Astronomy and Space Physics of the T. G. Shevchenko Kyiv Order of Lenin State University.
Since 1977 he has been working at the Main Astronomical Observatory of the Academy of Sciences of the Ukrainian SSR (since 1991, the National Academy of Sciences of Ukraine.
In 1984 he defended his candidate's dissertation at the Institute of Astrophysics and Atmospheric Physics of the Academy of Sciences of the Estonian SSR on the topic "Investigation of the formation of molecular hydrogen and the conditions for the formation of stars in an environment with a primary chemical composition".
In 1992 he defended a doctoral dissertation at the Main Astronomical Observatory of the National Academy of Sciences of Ukraine in the specialty 01.03.02. - astrophysics, radio astronomy on the theme: "Physics of blue compact carnivorous galaxies and the problem of their formation".
In the 1990s, together with T.H. Thuan (USA), V.A. Lipovetsky and other colleagues from the Special Astrophysical Observatory conducted in-depth studies of blue compact galaxies found in the KISS (Kitt Peak Observatory) and Hamburg-SAO surveys containing active star-forming galaxies, studying the content of heavy elements and gas.
In 2000 he was elected a corresponding member of the National Academy of Sciences of Ukraine.
Since 2000, he has been in charge of the department of physics of vision and galaxies of the Main Astronomical Observatory of National Academy of Sciences of Ukraine.
2009 together with Shtanov Yu. V. and Guseva N. G. became the winner of the E. P. Fedorov prize of the National Academy of Sciences of Ukraine for the series of works "Blue Dwarf Galaxies and Problems of Dark Matter".
February 04, 2009 was elected academician of National Academy of Sciences of Ukraine in the field of astrophysics.
He worked as a senior researcher at the Main Astronomical Observatory of National Academy of Sciences of Ukraine in the Department of Physics of the Stars and Galaxies, then he was head of the department.
Awarded with certificates of honor of the Cabinet of Ministers of Ukraine and the Verkhovna Rada of Ukraine, winner of the award "Leader of Science of Ukraine 2016. Web of Science Award".
In April 2016 he moved to the Department of Astronomy and Astrophysics at the M. M. Bogolyubov Institute of Theoretical Physics of the National Academy of Sciences of Ukraine. Currently Senior Research Fellow at the position of Chief Scientist of the Department of Astrophysics and Elementary Particles.
His scientific interests are concentrated in the physics of extant galaxies. Known for the study of the physical and evolutionary properties of dwarf galaxies and star formation. He determined the amount of primary helium and the density of baryon matter in the universe. He proved the possibility of the formation of galaxies from primitive matter in the modern era. Established the existence of young galaxies at short distances from our galaxy. The galaxy he discovered was named Izot.
In 2005, he and American astronomer Trinh Tuan discovered the youngest galaxy.
He is author of more than 250 scientific papers, published mainly in leading international publications, such as "Nature" and "The Astrophysical Journal"
A group of researchers from five countries led by Yu. I. Izotov proved the reasons for the reionization of the universe.
Discovered the young galaxies in the local Universe and proved that their vision is formed in compact superstructures of stars that are 10 billion times brighter than the Sun.
He, together with I. G. Kolesnik based on the analysis of elemental processes in the primary substance of the universe has received new results on the concentration of molecular hydrogen and the characteristics of the first generation of vision.
In the 90's of the twentieth century. Yu. I. Izotov and N.G. Guseva, together with specialists from the USA, France and Germany, most accurately determined the content of primary helium, which was formed in the first minutes of existence of the Universe.
