THE ROLE OF RADIO WAVE PROPAGATION EFFECTS IN THE SOLAR CORONA TO INTERPRET THE BEHIND-LIMB BURSTS

Radio Physics and Radio Astronomy, 2016
Purpose: The radio emission propagation of solar radio bursts in the solar corona which sources are located on the far side of the Sun relative to the observer on Earth is studied.

A Search for Active Galactic Nuclei in Sc Galaxies with H II Spectra [PDF]

, 2002
(Abridged) We have searched for nuclear radio emission from a statistically complete sample of 40 Sc galaxies within 30 Mpc that are optically classified as star-forming objects, in order to determine whether weak AGNs might be present.

A New Component from the Quiet Sun from Radio to Gamma Rays: Synchrotron Radiation by Galactic Cosmic-Ray Electrons

The Astrophysical Journal, 2023
The quiet Sun, i.e., in its nonflaring state or nonflaring regions, emits thermal radiation from radio to ultraviolet. The quiet Sun also produces nonthermal radiation observed in gamma rays due to interactions of Galactic cosmic rays (GCRs) with the ...

Two dimensional time evolution of beam-plasma instability in the presence of binary collisions [PDF]

, 2016
Energetic electrons produced during solar flares are known to be responsible for generating solar type III radio bursts. The radio emission is a byproduct of Langmuir wave generation via beam-plasma interaction and nonlinear wave-wave and wave-particle ...

On the association of solar radio emission and solar prominences. [PDF]

The Astronomical Journal, 1956
Prominence cinematograms made at Sacramento Peak and climax in the years 1949?55 have been examined and compared with the solar radio records at 167 Mc/s. No close connexion was found between limb events and radio events, but some eruptions were found to be associated with simultaneous radio bursts. Three such cases are discussed in detail.

Periodic Bursts of Coherent Radio Emission from an Ultracool Dwarf [PDF]

, 2007
We report the detection of periodic (p = 1.96 hours) bursts of extremely bright, 100% circularly polarized, coherent radio emission from the M9 dwarf TVLM 513-46546. Simultaneous photometric monitoring observations have established this periodicity to be
