Probing the Physics of the Solar Corona with High-Resolution Observations using SKA-Mid
Mark C. M. Cheung, John S. Morgan, Rohit Sharma +3
We examine the capability of the SKA-Mid telescope for probing solar coronal structure and evolution. Using radiative magnetohydrodynamics simulations of a solar flare, we synthesi…
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…
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…
Dynamics of the coronal magnetic field in the 2022-10-02 X-class flare
Gregory D. Fleishman, Tatyana Kaltman, Sijie Yu
Solar flares are driven by release of free magnetic energy and often associated with restructurization of the magnetic field topology. Yet, observations of evolving magnetic field…
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…
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…
Atacama Large Aperture Submillimeter Telescope (AtLAST) Science: Solar and stellar observations
Sven Wedemeyer, Miroslav Barta, Roman Brajsa +35
Observations at (sub-)millimeter wavelengths offer a complementary perspective on our Sun and other stars, offering significant insights into both the thermal and magnetic composit…
Magnetic Energy Powers the Corona: How We Can Understand its 3D Storage & Release
Amir Caspi, Daniel B. Seaton, Roberto Casini +12
The coronal magnetic field is the prime driver behind many as-yet unsolved mysteries: solar eruptions, coronal heating, and the solar wind, to name a few. It is, however, still poo…
SSALMON - The Solar Simulations for the Atacama Large Millimeter Observatory Network
S. Wedemeyer, T. Bastian, R. Brajsa +27
The Solar Simulations for the Atacama Large Millimeter Observatory Network (SSALMON) was initiated in 2014 in connection with two ALMA development studies. The Atacama Large Millim…
GRB spectral parameter modeling
Gregory D. Fleishman, Fedor A. Urtiev
Fireball model of the gamma-ray bursts (GRBs) predicts generation of numerous internal shocks, which efficiently accelerate charged particles and generate relatively small-scale st…
Diffusive Radiation in One-dimensional Langmuir Turbulence
Gregory D. Fleishman, Igor N. Toptygin
We calculate spectra of radiation produced by a relativistic particle in the presence of one-dimensional Langmuir turbulence which might be generated by a streaming instability in…
