Spectral decoherence without depolarization in curvature radiation
A. G. Tevzadze, N. L. Shatashvili
Context: Fast radio bursts often exhibit strong linear polarization together with pronounced spectral structure. Yet in coherent curvature radiation, spectral decoherence and depol…
Flow Generation via Catastrophic Loss of Equilibrium in Weakly-Rotating Self-Gravitating Fluids: A Minimal Idealized Model
L. Gudushauri, N. L. Shatashvili, G. Shekiladze +1
This paper explores the catastrophic energy transformations, in particular the ones leading to the generation of a flow in a weakly rotating self-gravitating fluid/gas found, for i…
On Lorentz Variability of Magnetically Dominated Relativistic Outflows
V. I. Berezhiani, N. L. Shatashvili, A. G. Tevzadze
We show that magnetized relativistic outflows can exhibit a relativistic effect in which Lorentz transformation maps spatially extended magnetic field structure into apparent tempo…
Catastrophic Formation of Macro-Scale Flow and Magnetic Fields in the Relativistic Gas of Binary Systems
E. Saralidze, N. L. Shatashvili, S. M. Mahajan +1
It is shown that a simple quasi-equilibrium analysis of a multi-component plasma can be harnessed to explain catastrophic energy transformations in astrophysical objects. We limit…
Jet formation model from accretion disks of electron-ion-photon gas
E. Katsadze, N. Revazashvili, N. L. Shatashvili
The problem of Astrophysical Jet formation from relativistic accretion disks through the establishment of relativistic disk-powerful jet equilibrium structure is studied applying t…
