Persistence of Plasma Waves in the Heliosphere and Beyond
Ketevan Arabuli, Andria Rogava
Dynamics of Langmuir modes - Langmuir waves (LW) and shear Langmuir vortices (SLV) - in kinematically complex astrophysical plasma flows is studied. It is found that they exhibit a…
Centrifugally driven relativistic particles: general treatment and new solutions
Giorgi Khomeriki, Andria Rogava
Dynamics of a centrifugally driven particle moving along a magnetically prescribed trajectory (e.g. pulsar magnetic field line) in a spacetime of a rotating massive body is conside…
Self-trapping as the possible beaming mechanism for FRB
George Machabeli, Andria Rogava, Beka Tevdorashvili
Mysterious Fast Radio Bursts (FRB), still eluding a rational explanation, are astronomical radio flashes with durations of milliseconds. They are thought to be of an extragalactic…
Emission of extremely bright gamma-ray pulsar in the Large Magellanic Cloud
George Machabeli, Andria Rogava, Nino Chkheidze
In the present paper a theoretical interpretation of observational characteristics of the pulsar PSR J0540-6919 is suggested. In particular, we provide a theoretical model explaini…
Electrostatic ion perturbations in kinematically complex shear flows
Z. Osmanov, A. Rogava, S. Poedts
The scope of the present paper is to determine how ion electrostatic wave perturbations in plasma flows are influenced by the presence of a kinematically complex velocity shear. Fo…
On the origin and physics of Gamma Flares in Crab Nebula
George Machabeli, Andria Rogava, David Shapakidze
We consider parametric generation of electrostatic waves in the magnetosphere of the pulsar PSR0531. It is shown that in the framework of this mechanism it is possible to convert t…
