General Information

The physical and mathematical sciences have been one of Kharkiv V. N. Karazin National University's strengths from the beginning. The Department of Space Radio Physics is the youngest constituent department in the School of Radio Physics. It admitted its first students in 1964.

Research in the department is conducted in the following two fields:
(1) space research and
(2) astronomy research.
Students are free to choose one of these areas, space research or astronomy.

The space research branch was established in 1964 by Prof. V. A. Misyura.

The astronomy branch was established in 1976 by Prof. L. N. Litvinenko  http://ira.kharkov.ua/eng_main.htm. The astronomy research is conducted in the Institute of Radio Astronomy, National Academy of Sciences of Ukraine  (4 Krasnoznamennaya St., Kharkiv, 61002 Ukraine).

The Department now occupies a few spacious rooms in the main building of Kharkiv V. N. Karazin National University at the center of Kharkiv and operates Radiophysical Observatory. The Radiophysical Observatory is a unique facility in Ukraine allowing observations of ionospheric features and response over an altitude range from ~60 to 1000 km to be made simultaneously with magnetometer measurements.

The department's reputation is grounded in its research work. The creativity and enthusiasm of Department's staff generates an international reputation in major areas of research including radio wave propagation, ionospheric and space physics.

Kharkiv V. N. Karazin National University's Radiophysical Observatory, located approximately 50 km south of Kharkiv city, is a nationally sponsored facility for research and development in near-Earth space environment physics. The Radiophysical Observatory employs 41 persons.

The Radiophysical Observatory is located on a 50-acre delightful green hilltop overlooking the Donets River near Gaydary settlement. An Affiliate of the Radiophysical Observatory is located on the site of the Ukrainian HF Radio Telescope of the Institute for Radio Astronomy at Grakovo settlement where the Department occupies a few rooms.

The faculty has published about thirty textbooks. The latest textbooks

Astronomical Research

Astronomy at the Kharkiv National University has a long and renowned history. Both the Astronomical Department and Astronomical Observatory were established in the middle of the 19-th century, and since that time, have noticeably contributed into the world science. Several branches of astronomy is being presently developed in the Kharkiv Astronomical Observatory, which are all can be seen at:

http://astron.kharkov.ua/

Investigation of gravitationally lensed quasars should be particularly noted, which is being successfully developed at present by the Institute of Radio Astronomy of the National Academy of Sciences of Ukraine (Kharkiv) in cooperation with the Ulugh Beg Astronomical Institute of the Academy of Sciences of Uzbekistan (Tashkent). A strong joint team has been created that successfully studies all the aspects of a gravitational lensing phenomenon: from observations of specific gravitational lens systems to the theoretic analysis of data and simulation of physical processes in quasars and lensing galaxies. More details can be seen at:

http://astron.kharkov.ua/dip/results.htm

The Kharkiv V. N. Karazin National University Astronomical Observatory has experience in:

    • high-resolution observations of faint sources
    • creating specific algorithms for photometric image processing of faint compact sources with a complicated structure
    • analytical solutions for some mechanisms of the gravitational lensing phenomenon
    • numerical simulation of transient phenomena in gravitational lens systems

A two-component coil magnetometer is installed at the Affiliate of the Radiophysical Observatory, one of the electromagnetically quietest locations, the settlement Grakovo, about seventy kilometers from Kharkiv city and at approximately the same distance from the Radiophysical Observatory. The magnetometer and data recording system acquire measurements in the south-north (H component) and west-east (D) directions at half-second intervals in the 0.001-1 Hz frequency band within which the magnetometer delivers differential performance. The internal noise level shows the following frequency dependence: 0.5 pT at f = 1 Hz, 5 pT at f=0.1 Hz, and 50 pT at f = 0.01 Hz. The data are autonomously recorded on a hard disk during about two months, and then the data have to be collected by a visiting researcher.
