Statistical Modeling of Solar Flare Activity from Empirical Time Series of Soft X-ray Solar Emission
A. A. Stanislavsky, K. Burnecki, M. Magdziarz +2
A time series of soft X-ray emission observed on 1974-2007 years (GOES) is analyzed. We show that in the periods of high solar activity 1977-1981, 1988-1992, 1999-2003 the energy s…
On the connection between gamma and radio radiation spectra in pulsars
V. M. Kontorovich, A. B. Flanchik
The model of pulsar radio emission is discussed in which a coherent radio emis-sion is excited in a vacuum gap above polar cap of neutron star. Pulsar X and gamma radiation are con…
On the possible nature of Bp-Ap Stars: an application to HD101065 and HR465
V. F. Gopka, O. M. Ulyanov, S. M. Andrievsky
We have proposed the new explanation of some magnetic chemically peculiar (MCP) stars anomalies, which is based on assumption that such stars can be the close binary systems with a…
Scattering of Low-Frequency Radiation by a Gyrating Electron
S. A. Petrova
The scattering of electromagnetic radiation by the particle gyrating in an external magnetic field is considered. Particular attention is paid to the low-frequency case, when the f…
On the Nature of Precursors in the Radio Pulsar Profiles
S. A. Petrova
In the average profiles of several radio pulsars, the main pulse is accompanied by the preceding component. This so called precursor is known for its distinctive polarization, spec…
Physics of Interpulse Emission in Radio Pulsars
S. A. Petrova
The magnetized induced Compton scattering off the particles of the ultrarelativistic electron-positron plasma of pulsar is considered. The main attention is paid to the transverse…
Q2237+0305 source structure and dimensions from light curves simulation
V. G. Vakulik, R. E. Schild, G. V. Smirnov +2
Assuming a two-component quasar structure model consisting of a central compact source and an extended outer feature, we produce microlensing simulations for a population of star-l…
A Dipole Vortex Model of Obscuring Tori in Active Galaxy Nuclei
Elena Yu. Bannikova, Victor M. Kontorovich
The torus concept as an essential structural component of active galactic nuclei (AGN) is generally accepted. Here, the situation is discussed when the torus "twisting" by the radi…
Radio recombination lines from the largest bound atoms in space
S. V. Stepkin, A. A. Konovalenko, N. G. Kantharia +1
In this paper, we report the detection of a series of radio recombination lines (RRLs) in absorption near 26 MHz arising from the largest bound carbon atoms detected in space. Thes…
Instantaneous Radio Spectra of Giant Pulses from the Crab Pulsar from Decimeter to Decameter Wavelengths
M. V. Popov, A. D. Kuzmin, O. M. Ul'yanov +7
The results of simultaneous multifrequency observations of giant radio pulses from the Crab pulsar, PSR B0531+21, at 23, 111, and 600 MHz are presented and analyzed. Giant pulses w…
Nature of giant pulses in radio pulsars
S. A. Petrova
Formation of giant radio pulses is attributed to propagation effects in the plasma of pulsar magnetosphere. Induced scattering of radio waves by the plasma particles is found to le…
Statistics of the individual-pulse polarization based on propagation effects in pulsar magnetosphere
S. A. Petrova
Pulsar radio emission is modelled as a sum of two completely polarized non-orthogonal modes with the randomly varying Stokes parameters and intensity ratio. The modes are the resul…

S. A. Petrova
Propagation of radio waves in the ultrarelativistic magnetized electron-positron plasma of pulsar magnetosphere is considered. Polarization state of the original natural waves is f…

We present new brightness monitoring observations of the 4 components of gravitationally lensed system Q2237+0305, which show detection of an intrinsic quasar brightness fluctuatio…
How to improve the High Frequency capabilities of SRT
T. Pisanu, M. Morsiani, C. Pernechele +2
The SRT (Sardinia Radio Telescope) is a general purpose, fully steerable, active surface equipped, 64 meters antenna, which is in an advanced construction state near Cagliari (Sard…

In 2003, Kuan, Charnley, and co-workers reported the detection of interstellar glycine (NH2CH2COOH) based on observations of 27 lines in 19 different spectral bands in one or more…
Gravitational Collapse and Equilibrium Conditions of a Toroidal Vortex with Thermal Pressure
K. Yu. Bliokh, V. M. Kontorovich
We found equilibrium conditions for a self-gravitating toroidal vortex by taking into account thermal pressure. These conditions are shown to significantly differ from those for a…
