## Blazar Observations at the RT-32 Radio Telescope of the IAA RAS Svetloe Observatory

Transactions of IAA RAS, issue 51, 13–19 (2019)

Keywords: blazars, active galactic nuclei, flux density, radio telescope, spectrum

### Abstract

The first observational results obtained at the Svetloe Observatory of the IAA RAS under the WEBT — World Blazar Telescope project [1-2] are presented. This international project, led by Italian astronomers, combines the efforts of observatories around the world and is aimed at a comprehensive study of the active nuclei of galaxies in the entire range of the electromagnetic spectrum, from radio waves to gamma radiation. The Svetloe Observatory joined the project in March 2018 and since then has been conducting regular observations as the part of the “Scale” program on the RT-32 telescope at frequencies of 4.8 and 8.5 GHz. The first results of measuring the flux density at the frequencies given above were obtained for several objects. The results of monitoring the radio flux density of the blazar 3C 279, being one of the most active sources of this type, are discussed. These data were transmitted to the Torino Observatory and will be used within the WEBT project.
