Review of Machine Learning Models for Solar Energetic Particle Prediction
Spiridon Kasapis, Pouya Hosseinzadeh, Kathryn Whitman +73
Solar energetic particle (SEP) events have attracted increasing attention due to their significant radiation hazards for aviation, spacecraft electronics, and human missions beyond…
Probing the Turbulent Corona and Heliosphere Using Radio Spectral Imaging Observation during the Solar Conjunction of Crab Nebula
Peijin Zhang, Surajit Mondal, Bin Chen +41
Measuring plasma parameters in the upper solar corona and inner heliosphere is challenging because of the region's weakly emissive nature and inaccessibility for most in situ obser…
Magnetic Field Evolution of the Solar Active Region 13664
Robert Jarolim, Astrid Veronig, Stefan Purkhart +2
On 2024 May 10/11, the strongest geomagnetic storm since November 2003 has occurred, with a peak Dst index of -412 nT. The storm was caused by NOAA Active Region (AR) 13664, which…
Weak Solar Radio Bursts from the Solar Wind Acceleration Region Observed by Parker Solar Probe and Its Probable Emission Mechanism
Ling Chen, Bing Ma, Dejin Wu +7
The Parker Solar Probe (PSP) provides us the unprecedentedly close approach observation to the Sun, and hence the possibility of directly understanding the "elementary process" whi…
Coronal Diagnostics of Solar Type-III Radio Bursts Using LOFAR and PSP Observations
Mohamed Nedal, Kamen Kozarev, Peijin Zhang +1
This study aims to investigate the ambiguous source and the underlying physical processes of the solar type III radio bursts that occurred on April 3, 2019, through the utilization…
Forecasting Solar Energetic Proton Integral Fluxes with Bi-Directional Long Short-Term Memory Neural Networks
Mohamed Nedal, Kamen Kozarev, Nestor Arsenov +1
Solar energetic particles are mainly protons and originate from the Sun during solar flares or coronal shock waves. Forecasting the Solar Energetic Protons (SEP) flux is critical f…
Source positions of an interplanetary type III radio burst and anisotropic radio-wave scattering
Xingyao Chen, Eduard P. Kontar, Nicolina Chrysaphi +7
Interplanetary solar radio type III bursts provide the means for remotely studying and tracking energetic electrons propagating in the interplanetary medium. Due to the lack of dir…
RFI Flagging in Solar and Space Weather Low Frequency Radio Observations
Peijin Zhang, André R. Offringa, Pietro Zucca +2
Radio spectroscopy provides a unique inspection perspective for solar and space weather research, which can reveal the plasma and energetic electron information in the solar corona…
Radio Studies of the Middle Corona: Current State and New Prospects in the Next Decade
Bin Chen, Jason E. Kooi, David B. Wexler +13
The "middle corona," defined by West et al. (2022) as the region between ~1.5-6 solar radii, is a critical transition region that connects the highly structured lower corona to the…
Detecting the oscillation and propagation of the nascent dynamic solar wind structure at 2.6 solar radii using VLBI radio telescopes
Maoli Ma, Guifre Molera Calves, Giuseppe Cimo +29
Probing the solar corona is crucial to study the coronal heating and solar wind acceleration. However, the transient and inhomogeneous solar wind flows carry large-amplitude inhere…
FastQSL: A Fast Computation Method for Quasi-separatrix Layers
Peijin Zhang, Jun Chen, Rui Liu +1
Magnetic reconnection preferentially takes place at the intersection of two separatrices or two quasi-separatrix layers, which can be quantified by the squashing factor Q, whose ca…
Interferometric imaging, and beam-formed study of a moving Type IV Radio burst with LOFAR
Hongyu Liu, Pietro Zucca, Kyung-Suk Cho +6
Type IV radio burst has been studied for over 50 years. However, the specifics of the radio emission mechanisms is still an open question. In order to provide more information abou…
Imaging of the Quiet Sun in the Frequency Range of 20-80 MHz
PeiJin Zhang, Pietro Zucca, Kamen Kozarev +7
Radio emission of the quiet Sun is considered to be due to thermal bremsstrahlung emission of the hot solar atmosphere. The properties of the quiet Sun in the microwave band have b…
