The low frequency VLBI of URAN network operated in the decameter range has been designed in Ukraine to study cosmic radio sources. The network consists of five radio telescopes making up of four interferometers with baselines range from 42 to 913 km

Results of observations of the solar sporadic radio emission in decameter range are presented. These observations were carried out at UTR-2 radio telescope with 60-channel spectrometer and DSP (Digital Spectral Polarimeter) last years. Particular att

We report the results of UTR-2 radio telescope observations of an absorption burst at the decameter range. This event is associated with two consecutive M-class flares and happened after the second M-flare. The latter flare was accompanied by Type II

It is known that the spatial distribution of galaxies and quasars is structured at a scale LS = 130 h⁻¹Mpc. The same scale can be present at a spatial distribution of the physical characteristics of quasars. The search of period ≈ LS was conduct

The paper describes the results of modernization of the calibration system commutation devices and a check of pattern parameters of the UTR-2 radio telescope. As a result of the modernization an effective area of the telescope has been increased by 2

Periodicity in galaxy distribution on distances was detected in pencil beams of deep redshifts surveys of galaxies. A priori probability of the appearance of such periodicity is 10−8 [5] even at the presence of the selected scale in a correlation f

The general formulae that describe radiation of an ultrarelativistic electron moving along spiral trajectories with a small pitch angle in curved magnetic force lines are considered. These formulae can be identical to either synchrotron radiation or

Significance variations of lunar radio flux at the wavelength of 2.46 cm were detected in Irbene (Latvia) during the maxima of Leonid shower on the Moon in 2000 and 2001. These results were interpreted as detection of lunar radio emission of seismic
