Scattering of ultrastrong electromagnetic waves by magnetized particles [PDF]

open access: yes, 2021
Observations of powerful radio waves from neutron star magnetospheres raise the question of how strong waves interact with particles in a strong background magnetic field $B_{bg}$. This problem is examined by solving the particle motion in the wave.

Detection of acoustic-gravity waves in lower ionosphere by VLF radio waves [PDF]

open access: yesNina, A., and V. M. \v{C}ade\v{z} (2013), Detection of acoustic-gravity waves in lower ionosphere by VLF radio waves, Geophys. Res. Lett., 40, 4803-4807, 2017
We present a new method to study harmonic waves in the low ionosphere (60 - 90 km) by detecting their effects on reflection of very low frequency (VLF) radio waves. Our procedure is based on amplitude analysis of reflected VLF radio waves recorded in real time, which yields an insight into the dynamics of the ionosphere at heights where VLF radio waves

A new list of extra-galactic radio jets [PDF]

open access: yesPublished at A&A, 381, 757 (2002), 2002
A catalogue of extra-galactic jets is very useful both in observational and theoretical studies of active galaxies. With the use of new powerful radio instruments, the detailed structures of very compact or weak radio sources are investigated observationally and many new radio jets are detected.

LOFAR observations of radio burst source sizes and scattering in the solar corona [PDF]

open access: yesA&A 645, A11 (2021), 2020
Low frequency radio wave scattering and refraction can have a dramatic effect on the observed size and position of radio sources in the solar corona. The scattering and refraction is thought to be due to fluctuations in electron density caused by turbulence.

Development of a methodology to estimate a region and waiting period for strong Kamchatka earthquakes based on seismic and ionospheric predictive signs [PDF]

open access: yesE3S Web of Conferences, 2019
In this paper, an attempt is made to combine seismological and ionospheric predictive signs formed on the eve of earthquakes in order to develop a methodology for assessing the region and the time period of waiting for strong Kamchatka earthquakes with ...
