Magnetic holes are structures commonly observed in various space plasma environments throughout the solar system, including the solar wind. These structures are characterized by a…
Estimating the total energy content in escaping accelerated solar electron beams
Alexander W. James, Hamish A. S. Reid
Quantifying the energy content of accelerated electron beams during solar eruptive events is a key outstanding objective that must be constrained to refine particle acceleration mo…
Imaging a large coronal loop using type U solar radio burst interferometry
Jinge Zhang, Hamish A. S. Reid, Eoin Carley +4
Solar radio U-bursts are generated by electron beams traveling along closed magnetic loops in the solar corona. Low-frequency ( 100 MHz) U-bursts serve as powerful diagnostic to…
The Link Between Non-Thermal Velocity and Free Magnetic Energy in Solar Flares
James McKevitt, Robert Jarolim, Sarah Matthews +5
The cause of excess spectral line broadening (non-thermal velocity) is not definitively known, but given its rise before and during flaring, the causal processes hold clues to unde…
Solar Electron Beam -- Langmuir Wave Interactions and How They Modify Solar Electron Beam Spectra: Solar Orbiter Observations of a Match Made in the Heliosphere
Camille Y. Lorfing, Hamish A. S. Reid, Raul Gomez-Herrero +7
Solar Orbiter's four in-situ instruments have recorded numerous energetic electron events at heliocentric distances between 0.5 and 1au. We analyse energetic electron fluxes, spect…
The need for focused, hard X-ray investigations of the Sun
Lindsay Glesener, Albert Y. Shih, Amir Caspi +46
Understanding the nature of energetic particles in the solar atmosphere is one of the most important outstanding problems in heliophysics. Flare-accelerated particles compose a hug…
Deriving Large Coronal Magnetic Loop Parameters Using LOFAR J burst Observations
Jinge Zhang, Hamish A. S. Reid, Vratislav Krupar +3
Large coronal loops around one solar radius in altitude are an important connection between the solar wind and the low solar corona. However, their plasma properties are ill-define…
Spectral Analysis of Solar Radio Type III Bursts from 20 kHz to 410 MHz

We present the statistical analysis of the spectral response of solar radio type III bursts over the wide frequency range between 20 kHz and 410 MHz. For this purpose, we have used…
Common origin of quasi-periodic pulsations in microwave and decimetric solar radio bursts
Larisa Kashapova, Dmitrii Kolotkov, Elena Kupriyanova +3
We analyse quasi-periodic pulsations (QPP) detected in the microwave and decimeter radio emission of the SOL2017-09-05T07:04 solar flare, using simultaneous observations by the Sib…
Observations of shock propagation through turbulent plasma in the solar corona
Eoin P. Carley, Baptiste Cecconi, Hamish A. Reid +14
Eruptive activity in the solar corona can often lead to the propagation of shock waves. In the radio domain the primary signature of such shocks are type II radio bursts, observed…
Localised acceleration of energetic particles by a weak shock in the solar corona
David M. Long, Hamish A. S. Reid, Gherardo Valori +1
Globally-propagating shocks in the solar corona have long been studied to quantify their involvement in the acceleration of energetic particles. However, this work has tended to fo…
Fine structure of type III solar radio bursts from Langmuir wave motion in turbulent plasma
Hamish A. S. Reid, Eduard P. Kontar
The Sun frequently accelerates near-relativistic electron beams that travel out through the solar corona and interplanetary space. Interacting with their plasma environment, these…
