Modeling brightness temperature of sunspots using ALMA single-dish observations
F. MatkoviÄ, R. BrajÅ¡a, A. O. Benz +5
We model sunspot brightness temperature in the wavelength range 0.3-10mm using the Atacama Large Millimeter/submillimeter Array (ALMA) single-dish measurements together with other…
Modeling brightness temperature of prominences on the solar disk using ALMA single-dish observations
F. MatkoviÄ, R. BrajÅ¡a, A. O. Benz +5
Prominences (PRs) are among the most common solar phenomena, yet their full physical picture, particularly their chromospheric mm emission, remains incomplete. The new Atacama Larg…
Observation of an Extraordinary Type V Solar Radio Burst: Nonlinear Evolution of the Electron Two-Stream Instability
Arnold O. Benz, Clemens R. Huber, Vincenzo Timmel +1
Solar type V radio bursts are associated with type III bursts. Several processes have been proposed to interpret the association, electron distribution, and emission. We present th…
The observational evidence that all microflares that accelerate electrons to high energies are rooted in sunspots
Andrea Francesco Battaglia, Säm Krucker, Astrid M. Veronig +6
In general, large solar flares are more efficient at accelerating high-energy electrons than microflares. Nonetheless, we sometimes observe microflares that accelerate electrons to…
