The Astrophysical JournalWe present a comprehensive study of type III radio bursts and their association with solar flares of magnitude M1.0 and larger, as observed by four widely separated spacecraft (Parker Solar Probe, Solar Orbiter, STEREO-A, and Wind). Our main focus is the

Fine structure events in microwave emission during solar minimum
Solar-Terrestrial Physics, 2019 The solar minimum is a period with a relatively smaller number of sunspots and solar eruptions, and has been less studied before. Since the radio signal rapidly responds to the change of solar plasma and magnetic field, we perform a comprehensive ...

Development of solar flares and features of the fine structure of solar radio emission [PDF]
Geomagnetism and Aeronomy, 2017 The reason for the occurrence of different elements of the fine structure of solar radio bursts in the decimeter and centimeter wavelength ranges has been determined based on all available data from terrestrial and satellite observations. In some phenomena, fast pulsations, a zebra structure, fiber bursts, and spikes have been observed almost ...

Periodicities in microwave radio bursts of solar flares [PDF]
Proceedings of the International Astronomical Union, 2006 We analyze the periodicities for 294 solar flares observed by Nobeyama Radioheliograph over 6 discrete frequencies of 1, 2, 3.75, 9.4, 17 and 35 GHz during the solar cycle 23 between 1998 and 2004. Using Fourier analysis, we pick up the shortest period ($T_{\rm{s}}$) for each event at each frequency channel.

Particle acceleration in the presence of weak turbulence at an X-type neutral point [PDF]
, 2012 We simulate the likely noisy situation near a reconnection region by superposing many 2D linear reconnection eigenmodes. The superposition of modes on the steady state X-type magnetic field creates multiple X- and O-type neutral points close to the ...

The Efficiency of Electron Acceleration during the Impulsive Phase of a Solar Flare
The Astrophysical Journal Letters, 2023 Solar flares are known to be prolific electron accelerators, yet identifying the mechanism(s) for such efficient electron acceleration in solar flare (and similar astrophysical settings) presents a major challenge.

RADIO EMISSION FROM SOLAR FLARES
Annual Review of Astronomy and Astrophysics, 1998 ▪ Abstract Radio emission from solar flares offers a number of unique diagnostic tools to address long-standing questions about energy release, plasma heating, particle acceleration, and particle transport in magnetized plasmas. At millimeter and centimeter wavelengths, incoherent gyrosynchrotron emission from electrons with energies of tens of kilo ...

Radio Signatures of Solar Flare Reconnection
The Astrophysical Journal, 2005 The time evolution of plasma parameters (density, magnetic field, etc.) in a two-dimensional MHD model of solar flare reconnection is computed numerically. Then assuming plasma radio emission from locations where the "double-resonance" instability generates upper hybrid waves due to unstable distribution function of suprathermal electrons, the radio ...
