Evidence for plasmoid formation related to a hot UV burst in the solar atmosphere
Mats Ola Sand, Luc Rouppe van der Voort, Souvik Bose +4
Magnetic reconnection in the solar atmosphere drives energetic phenomena such as Ellerman bombs, UV bursts, and surges. We used coordinated observations from the Swedish 1-m Solar…

Investigating white-light flare mechanisms via the Paschen jump using high-resolution continuum observations from the Swedish 1-m Solar Telescope
Sascha Ornig, Luc Rouppe van der Voort, Mats Carlsson +4
The continuum is understood to contain a large portion of the energy emitted by a solar flare. The optical continuum, known as white light (WL), is particularly relevant since it m…

IRIS NUV diagnostics for Ellerman bombs: spectral properties, thermodynamics, and formation height
I. J. Soler Poquet, C. J. Díaz Baso, A. Sainz Dalda +3
Context. Ellerman bombs (EBs) are observational signatures of small-scale magnetic reconnection, key to understanding the lower solar atmosphere. While their role in active regions…
