Spectral evolution of mildly relativistic electrons in solar flares
Gregory D. Fleishman, Tatyana Kaltman, Sijie Yu +1
Solar flares are a powerful engine capable of accelerating ambient plasma particles to high nonthermal energies. A key characteristic of these particles is their energy spectrum. N…
Radio Diagnostics of Particle Acceleration in Solar Flares with SKAO Observations
Rohit Sharma, Marina Battaglia, Sijie Yu +3
Particle acceleration is a fundamental astrophysical process occurring across diverse systems and scales, producing electromagnetic emission across all wavelengths. Radio bursts fr…
Radio Spectral Imaging and MHD Modeling of a CME-Driven Shock: Connecting Solar Type II Radio Bursts with Shock-Surface Magnetic Geometry
Peijin Zhang, Weihao Liu, Bin Chen +3
Solar type II radio bursts are widely regarded as signatures of shock waves propagating in the solar corona and are of particular importance for understanding shock-driven particle…
Summary of the First Year of the Space Weather Around Young Suns Program: 900 Hours of Low-frequency Radio and Optical Data Dedicated to Young, Solar-type Stars
Ivey Davis, Gregg Hallinan, Nikita Kosogorov +51
The Space Weather Around Young Suns (SWAYS) program was introduced in \citet{Davis2025} as a multi-wavelength monitoring program for studying the activity and particle environments…
All-Sky Ultra-Narrowband Spectral Imaging with the OVRO-LWA: Technosignature Constraints and Axion-Like Particle Prospects
Nikita Kosogorov, Gregg Hallinan, Greg Hellbourg +46
We present an imaging-domain search for technosignatures at decametric wavelengths with the OVRO-LWA, targeting ultra-narrowband continuous-wave signals between 50 and 86 MHz. We i…
On the Nature of Candle-Flame-Shaped Solar Flares and Sub-Alfvénic Supra-Arcade Plasma Downflows
Ivan Oparin, Sabastian Fernandes, Bin Chen +4
Certain solar flares exhibit a distinctive candle-flame or cusp-shaped feature above the bright flare arcade visible in extreme ultraviolet (EUV) and X-ray channels sensitive to hi…
Modeling the Thermal Low-Frequency Radio Sun with Ray Tracing
Peijin Zhang, Bin Chen, Gregory Fleishman +4
Incoherent radio emission at meter--decimeter wavelengths provides a key diagnostic of the coronal thermal plasma, but at frequencies below \,1\,GHz coronal refraction can su…
Implementation of a Near-Realtime Recording and Reporting System of Solar Radio Bursts
Peijin Zhang, Anastasia Kuske, Bin Chen +48
Strong solar activity is often accompanied by a variety of radio bursts. These bursts are valuable diagnostics of coronal and heliospheric processes and also have potential applica…
Estimating Electron Densities in the Middle Solar Corona using White-light and Radio Observations
Surajit Mondal, Shaheda Begum Shaik, Russell A. Howard +45
The electron density of the solar corona is a fundamental parameter in many areas of solar physics. Traditionally, routine estimates of coronal density have relied exclusively on w…
MeV-peaked electrons in a coronal source of a solar flare
Gregory D. Fleishman, Ivan Oparin, Gelu M. Nita +3
Analysis of γ-rays in solar flares has suggested a distinct continuum component dominating at MeV energies, which differs from the well-studied X-ray continuum produced by flare-ac…
Searches for Prompt Low-Frequency Radio Counterparts to Gravitational Wave Event S250206dm with the OVRO-LWA Time Machine
Nikita Kosogorov, Gregg Hallinan, Casey Law +46
We report on a search for prompt, low-frequency radio emission from the gravitational-wave (GW) merger S250206dm using the Owens Valley Radio Observatory Long Wavelength Array (OVR…
Starspots as the origin of ultrafast drifting radio bursts from an active M dwarf
Jiale Zhang, Hui Tian, Stefano Bellotti +16
Detecting coherent radio bursts from nearby M dwarfs provides opportunities for exploring their magnetic activity and interaction with orbiting exoplanets. However, it remains unce…
Possible First Detection of Gyroresonance Emission from a Coronal Mass Ejection in the Middle Corona
Surajit Mondal, Bin Chen, Xingyao Chen +45
Routine measurements of the magnetic field of coronal mass ejections (CMEs) have been a key challenge in solar physics. Making such measurements is important both from a space weat…
Microwave Imaging Spectroscopy Diagnosis of the Slow-rise Precursor of a Major Solar Eruption

In this Letter, taking advantage of microwave data from the Expanded Owens Valley Solar Array and extreme-ultraviolet (EUV) data from the Atmospheric Imaging Assembly, we present t…
Energy budget in the 2017-09-07 "cold" solar flare
Gregory D. Fleishman, Galina G. Motorina, Sijie Yu +1
A subclass of early impulsive solar flares, cold flares, was proposed to represent a clean case, where the release of the free magnetic energy (almost) entirely goes to acceleratio…
Anisotropic Turbulent Flows Observed in Above the Loop-top Regions During Solar Flares
