  • Absorption burst in the solar sporadic radio emission at 10−30 MHz frequencies 
    Konovalenko, A.A.; Stanislavsky, A.A.; Abranin, E.P.; Dorovsky, V.V.; Mel'nik, V.N. (Кинематика и физика небесных тел, 2005)
    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 ...
  • Angular structure of extragalactic radio sources at low frequencies 
    Brazhenko, A.I.; Koshovy, V.V.; Lozynsky, A.R.; Megn, A.V.; Rashkovsky, S.L.; Shepelev, V.A. (Кинематика и физика небесных тел, 2005)
    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 ...
  • Modernization of commutation devices and an improvement of main parameters of the UTR-2 radio telescope 
    Zakharenko, V.V.; Sharykin, N.K.; Rudavin, E.R. (Кинематика и физика небесных тел, 2005)
    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 ...
  • New decameter radiopolarimeter URAN-2 
    Brazhenko, A.I.; Bulatsen, V.G.; Vashchishin, R.V.; Frantsuzenko, A.V.; Konovalenko, A.A.; Falkovich, I.S.; Abranin, E.P.; Ulyanov, O.M.; Zakharenko, V.V.; Lecacheux, A.; Rucker, H. (Кинематика и физика небесных тел, 2005)
    The description of the new decameter radiopolarimeter is submitted. It is created based on the phased array URAN-2, which is the greatest decameter array in the world after UTR-2, having the effective area about 30 000 m2, ...
  • New methods and equipment of decametric radio astronomy for continuum observation at the UTR-2 radio telescope 
    Sidorchuk, K.M.; Konovalenko, A.A.; Rucker, H.O.; Lecacheux, A.; Denis, L.; Sidorchuk, M.A.; Rashkovsky, S.L.; Dorovsky, V.V.; Zakharenko, V.V. (Кинематика и физика небесных тел, 2005)
    At present time the modernization of the giant decametric radio telescope UTR-2 is under way. New back-end facilities and methods which open up new possibilities for radio astronomical observations are developed. Some ...
  • On the synchrotron radiation in curved magnetic lines 
    Sobolev, Ya.M. (Кинематика и физика небесных тел, 2005)
    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 ...
  • Relations of radio sources with jets parameters 
    Miroshnichenko, A.P. (Кинематика и физика небесных тел, 2005)
    We considered the sample of galaxies and quasars with jets based on observed data. We obtained the magnetic field strength in these objects using the condition of energy equipartition between the relativistic particles and ...
  • Research of the fine structure of the radio galaxy 3C 234 with radio interferometer URAN-2 
    Vashchishin, R.V.; Megn, A.V.; Rashkovsky, S.L.; Shepelev, V.A.; Inyutin, G.A.; Brazhenko, A.I.; Bulatsen, V.G. (Кинематика и физика небесных тел, 2005)
    The brief description and the basic characteristics of the radio interferometer URAN-2 aerial system, included in VLBI decameter system URAN, are presented. The research results of the 3C 234 angular structure with URAN ...
  • Searching of flat waves of density in spatial distribution of quasars 
    Khodyachikh, M. (Кинематика и физика небесных тел, 2005)
    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 ...
  • Sporadic solar radio emission at decameter wavelengths

    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) ...
  • The lunar radio flux during Leonid meteor showers and lunar eclipse 
    Volvach, A.E.; Berezhnoy, A.A.; Khavroshkin, O.B.; Kovalenko, A.V.; Smirnov, G.T. (Кинематика и физика небесных тел, 2005)
    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 ...
  • Variations of the quasar radio spectra with period 130 h⁻¹ Mpc 
    Khodyachikh, M. (Кинематика и физика небесных тел, 2005)
    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 ...
