  • A quasar sample for the Lyα forest studies from the Data Release 10 of the Sloan Digital Sky Survey 
    Torbaniuk, O. (Advances in Astronomy and Space Physics, 2015)
    We present a new sample of the z ≥ 2 quasar spectra. It contains 102 643 spectra which were visually selected from the SDSS DR10, and includes also a subsample of 65 976 spectra for the composite spectra compilation. This ...
  • A reconstruction method of electron density distribution in the equatorial region of magnetosphere 
    Shastun, V.V.; Agapitov, O.V. (Advances in Astronomy and Space Physics, 2015)
    A method for the estimation of electron density from the ratio of the wave magnetic and electric field amplitude of whistler waves is developed. Near the geomagnetic equator, whistler wave normals are mainly close to the ...
  • Cyclic Period Changes of β Lyrae-type Eclipsing Variable Stars KR Cyg, V382 Cyg and BX And 
    Tvardovskyi, D.E.; Marsakova, V.I. (Advances in Astronomy and Space Physics, 2015)
    We have studied three binary stellar systems KR Cyg, V382 Cyg and BX And, which are eclipsing variables of the β Lyrae - type. We have studied the phase curves and O-C curves. The forms of their O-C curves are sinusoidal ...
  • Diffusion processes in the transition layer of the Earth's magnetosphere 
    Prokhorenkov, A.S.; Kozak, L.V.; Lui, A.T.Y.; Gala, I.V. (Advances in Astronomy and Space Physics, 2015)
    Turbulence has a different nature in the interplanetary magnetic field and in the transition region, thus it requires a different type of analysis. The "Cluster 2" satellite mission provides magnetic measurements with a ...
  • Identification of the ~3.55 keV emission line candidate objects across the sky 
    Savchenko, D.O.; Iakubovskyi, D.A. (Advances in Astronomy and Space Physics, 2015)
    An emission line at the energy ∼3.55 keV detected in different galaxies and galaxy clusters has caused numerous discussions in high-energy astrophysics and particle physics communities. To reveal the origin of the line, ...
  • Magnetosheath and solar wind turbulence processes features identification 
    Prokhorenkov, A.S.; Kozak, L.V.; Lui, A.T.Y. (Advances in Astronomy and Space Physics, 2015)
    A different kind of analysis should be applied to a turbulent process, than that applied to a nondisturbed medium. In this work we present the result of extended self-similarity analysis (ESS) by comparing between different ...
  • The Galactic sky through H.E.S.S. eyes 
    Sushch, I. (Advances in Astronomy and Space Physics, 2015)
    The High Energy Stereosopic System (H.E.S.S.) is an array of five imaging atmospheric Cherenkov telescopes. Since 2003 it has been operating in the configuration of four 12 m telescopes complemented in 2012 by a much bigger ...
  • The luminosity - spectral index dependence of the X-ray bright Seyfert galaxies 
    Sadova, V.A.; Tugay, A.V. (Advances in Astronomy and Space Physics, 2015)
    X-ray luminosities and spectral indices of 97 bright Seyfert 1 (Sy1) galaxies from the XMM-Newton archive are analysed in this article. Distribution of these values is random, so we conclude that the model of emission ...
  • Wave-particle interactions in the outer radiation belts 
    Agapitov, O.V.; Mozer, F.S.; Artemyev, A.V.; Mourenas, D.; Krasnoselskikh, V.V. (Advances in Astronomy and Space Physics, 2015)
    Data from the Van Allen Probes have provided the first extensive evidence of non-linear (as opposed to quasilinear) wave-particle interactions in space, with the associated rapid (fraction of a bounce period) electron ...
