Limits on Fast Radio Burst–like Counterparts to Gamma-Ray Bursts Using CHIME/FRB

open access: yesThe Astrophysical Journal, 2023
Fast radio bursts (FRBs) are a class of highly energetic, mostly extragalactic radio transients lasting for ∼milliseconds. While over 600 FRBs have been published so far, their origins are presently unclear, with some theories for extragalactic FRBs ...

Radio Astronomical Tools for the Study of Solar Energetic Particles II.Time-Extended Acceleration at Subrelativistic and Relativistic Energies

open access: yesFrontiers in Astronomy and Space Sciences, 2021
Solar energetic particle (SEP) events are commonly separated in two categories: numerous “impulsive” events of relatively short duration, and a few “gradual” events, where SEP-intensities may stay enhanced over several days at energies up to several tens

A deep learning method for the recognition of solar radio burst spectrum [PDF]

open access: yesPeerJ Computer Science, 2022
Solar radiation is the excitation source that affects the weather in the atmosphere of the earth, and some solar activities such as flares and coronal mass ejections are often accompanied by radio bursts. The spectrum of solar radio bursts is helpful for

HIGH-FREQUENCY CUTOFF IN TYPE III BURSTS

open access: yesOdessa Astronomical Publications, 2016
In this article we report about a group of solar bursts with high-frequency cutoff, observed on 19 August of 2012 near 8:23 UT, simultaneously by three different radio telescopes: the Ukrainian decameter radio telescope (8-33 MHz), the French Nançay ...

New microstructure of decametre solar radio bursts

open access: yes, 1975
The fine structure of a variety of decametre solar radio bursts obtained with high temporal and frequency resolution spectrographs provides valuable information on the generation mechanisms of these bursts together with the physical conditions in the ...

The physical mechanisms of fast radio bursts

open access: yes, 2020
Fast radio bursts are mysterious millisecond-duration transients prevalent in the radio sky. Rapid accumulation of data in recent years has facilitated an understanding of the underlying physical mechanisms of these events.

The Statistical Polarization Properties of Coherent Curvature Radiation by Bunches: Application to Fast Radio Burst Repeaters

open access: yesThe Astrophysical Journal, 2023
Fast radio bursts (FRBs) are extragalactic radio transients with a millisecond duration and an extremely high brightness temperature. Very recently, some highly circularly polarized bursts were found in a repeater, FRB 20201124A. The significant circular

Characteristics of type III radio bursts and solar S bursts. Planetary Radio Emissions|PLANETARY RADIO EMISSIONS VIII 8|

open access: yes, 2018
The Sun is an active source of radio emission which is often associated with the acceleration of electrons arising from processes such as solar flares and coronal mass ejections (CMEs). At low radio frequencies (

"Slow" radio bursts from galactic magnetars?

open access: yes, 2021
Recently, one fast radio burst (FRB), FRB 200428, was detected from the Galactic magnetar soft gamma-ray repeater (SGR) J1935+2154 during one X-ray burst. This suggests that magnetars can make FRBs.
