Transmission enhancement in loss-gain multilayers by resonant suppression of reflection
Denis V. Novitsky, Vladimir R. Tuz, Sergey L. Prosvirnin +2
Using the transfer-matrix approach and solving time-domain differential equations, we analyze the loss compensation mechanism in multilayer systems composed of an absorbing transpa…
Molecules in the early Universe
B. Novosyadlyj, O. Sergijenko, V. M. Shulga
We study the formation of first molecules, negative Hydrogen ions and molecular ions in model of the Universe with cosmological constant and cold dark matter. The cosmological reco…
Validity of abundances derived from spaxel spectra of the MaNGA survey
L. S. Pilyugin, E. K. Grebel, I. A. Zinchenko +4
We measured the emission lines in the spaxel spectra of MaNGA galaxies in order to determine the abundance distributions therein. It has been suggested that the strength of the low…
Evolution features of giant sources with linear and break steep radio spectra
A. P. Miroshnichenko
In the framework of the cosmological model LambdaCDM the features of properties of giant radio sources with steep low-frequency spectra of linear (S) and break (C+) types are exami…
The search for radio emission from exoplanets using LOFAR low-frequency beam-formed observations: Data pipeline and preliminary results for the 55 Cnc system
Jake D. Turner, Jean-Mathias Grießmeier, Philippe Zarka +1
Detection of radio emission from exoplanets can provide information on the star-planet system that is difficult to study otherwise, such as the planetary magnetic field, magnetosph…
Induced Waveform Transitions of Dissipative Solitons
Bogdan A. Kochetov, Vladimir R. Tuz
The effect of an externally applied force upon dynamics of dissipative solitons is analyzed in the framework of the one-dimensional cubic-quintic complex Ginzburg-Landau equation s…
Imaging Spectroscopy of Solar Radio Burst Fine Structures
E. P. Kontar, S. Yu, A. A. Kuznetsov +6
Solar radio observations provide a unique diagnostic of the outer solar atmosphere. However, the inhomogeneous turbulent corona strongly affects the propagation of the emitted radi…
Control of single-mode operation in a circular waveguide filled by a longitudinally magnetized gyroelectromagnetic medium
Volodymyr I. Fesenko, Vladimir R. Tuz, Illia V. Fedorin +3
A substantial control of dispersion features of the hybrid EH01 and HE11 modes of a circular waveguide which is completely filled by a longitudinally magnetized composite finely-st…
Modal phenomena of surface and bulk polaritons in magnetic-semiconductor superlattices
Vladimir R. Tuz, Illia V. Fedorin, Volodymyr I. Fesenko
We discuss peculiarities of bulk and surface polaritons propagating in a composite magnetic-semiconductor superlattice influenced by an external static magnetic field. Three partic…
Weak-field limit of Kaluza-Klein models with spherically symmetric static scalar field: observational constraints
Alexander Zhuk, Alexey Chopovsky, Seyed Hossein Fakhr +2
In a multidimensional Kaluza-Klein model with Ricci-flat internal space, we study the gravitational field in the weak-field limit. This field is created by two coupled sources. Fir…
Cascade replication of dissipative solitons
Bogdan A. Kochetov, Vladimir R. Tuz
We report a new effect of a cascade replication of dissipative solitons from a single one. It is discussed in the framework of a common model based on the one-dimensional cubic-qui…
Oscillation of solar radio emission at coronal acoustic cut-off frequency
O. S. Pylaev, T. V. Zaqarashvili, A. I. Brazhenko +3
Recent SECCHI COR2 observations on board STEREO-A spacecraft have detected density structures at a distance of 2.5--15~R propagating with periodicity of about 90~minutes. The obser…
Stochastic Tools Hidden Behind the Empirical Dielectric Relaxation Laws
Aleksander Stanislavsky, Karina Weron
The paper is devoted to recent advances in stochastic modeling of anomalous kinetic processes observed in dielectric materials which are prominent examples of disordered (complex)…
Nonlinear reflection from the surface of neutron stars and puzzles of radio emission from the pulsar in the Crab nebula
Victor M. Kontorovich
Having no any explanations the radiation of high-frequency components of the pulsar in the Crab Nebula can be a manifestation of instability in the nonlinear reflection from the ne…
Crossing and anti-crossing effects of polaritons in a magnetic-semiconductor superlattice influenced by an external magnetic field
Vladimir R. Tuz, Volodymyr I. Fesenko, Illia V. Fedorin +2
Crossing and anti-crossing effects in dispersion characteristics of both bulk and surface polaritons in a magnetic-semiconductor superlattice influenced by an external static magne…
Rotational spectroscopy, tentative interstellar detection, and chemical modelling of N-methylformamide
A. Belloche, A. A. Meshcheryakov, R. T. Garrod +6
N-methylformamide, CH3NHCHO, may be an important molecule for interstellar pre-biotic chemistry because it contains a peptide bond. The rotational spectrum of the most stable trans…
