Abstract The identification of the X-ray 3.55-keV line as a recombination line of the π − tritium mesoatom is proposed. The formation of such an atom under standard astrophysical conditions without invoking new physics is shown to be possible in principle.
Abstract Using two volume-limited Main galaxy samples of the Sloan Digital Sky Survey Data Release 10 (SDSS DR10), we study u-band luminosity dependence of galaxy clustering by cluster analysis. Statistical results of two volume-limited Main galaxy samples are the same: luminous galaxies in M u...
Abstract The fine structure of the nucleus of the radio galaxy M 87 has been investigated at wavelengths of 2 and 3 cm. Its kinematics is determined by the inflow of the surrounding thermal plasma onto the “accretion disk, ” its transfer in a spiral to the center, and its ejection as a bipolar...
Abstract Based on data on Galactic masers with measured trigonometric parallaxes, we have tested a nonlinear model of Galactic rotation using generalized Oort formulas. This model is shown to yield pretty good results up to heliocentric distances of 3–4 kpc. The main feature of the method is the...
Abstract Based on masers with measured trigonometric parallaxes, we have redetermined the spatial orientation parameters of the Local (Orion) arm. Using 23 sources (the Gould Belt objects were excluded), we have found that their spatial distribution can be approximated by a very narrow ellipsoid...
Abstract When electrons are accelerated to relativistic energies in the inner gap of a pulsar, their motion is quantized in an external magnetic field and the electric field of the space charge of a rotating electron beam, an electromagnetic tornado appearing during breakdown in the pulsar’s...
Abstract Based on high-resolution spectra taken with the 1.9-m telescope of the South African Astronomical Observatory, we have determined the atmospheric parameters and chemical composition for three small-amplitude (AV Cir, BP Cir, and LR TrA), two classical (R TrA and S TrA), and one...
Abstract To study phenomenological properties of extensive air showers initiated by different particles (i.e., γ, p, Fe), CORSIKA simulations were used. We adopted a statistical method to produce diagrams of mean values of depth of shower maxima, 〈X max〉, versus energy decades. To be compared...
