Solar Radio Burst Fine Structures
Eduard Kontar, Daniel Clarkson, Hamish Reid +5
Solar radio bursts exhibit intricate variability in time, space, and frequency, often displaying a rich variety of fine frequency-time structures such as spikes, drift pairs, stria…
Imaging spectroscopy reveals spike-like repeating radio burst pairs in the solar corona
Suli Ma, Eduard P. Kontar, Daniel L. Clarkson +2
Solar radio bursts exhibit complex fine structures that reveal intricate coronal plasma dynamics. Here, we report detection of spike-like repeating burst pairs, characterized by tw…
Frequency-time-resolved Imaging Spectroscopy of Fine Structures in a Solar Radio Noise Storm
Daniel L. Clarkson, Eduard P. Kontar
Solar radio noise storms are common phenomena, composed of broadband continuum emission embedded with diverse fine structures, yet their unusually compact apparent sizes remain une…
Signatures of Large-Scale Magnetic Field Disturbances and Switchbacks in Interplanetary Type III Radio Bursts
Daniel L. Clarkson, Eduard P. Kontar
Type III solar radio bursts are driven by non-thermal electron beams travelling along heliospheric magnetic fields, with the radio emission frequency drift-rate determined by the b…
Ion-scale Turbulence and Energy Cascade Rate in the Solar Corona and Inner Heliosphere
Eduard P. Kontar, A. Gordon Emslie, Daniel L. Clarkson +1
Plasma turbulence cascading from MHD to kinetic scales in the heliospheric plasma is believed to play a key role in coronal heating and fast solar wind acceleration, but the proper…
Tracing the Heliospheric Magnetic Field via Anisotropic Radio-Wave Scattering
Daniel L. Clarkson, Eduard P. Kontar, Nicolina Chrysaphi +4
Astrophysical radio sources are embedded in turbulent magnetised environments. In the 1 MHz sky, solar radio bursts are the brightest sources, produced by electrons travelling alon…
