TL;DR: In this article, the presence and signatures of non-equilibrium processes, both non-Maxwellian distributions and nonequilibrium ionization, in the solar transition region, corona, solar wind, and flares are reviewed.

TL;DR: In this article, the statistical relationship between measured parameters (temperature, emission measure, etc.) of hot, thermal plasma in 37 intense (GOES M- and X-class) solar flares was determined using high-resolution imaging and spectroscopy observations from 6 to 100 keV.

TL;DR: In this article, a metric type II solar radio burst that occurred on the 3rd of November 2010 in association with an erupting plasmoid was observed by the Atmospheric Imaging Assembly (AIA) on board the Solar Dynamics Observatory and the Reuven Ramaty High Energy Solar Spectroscopic Imager, while the burst occurred in the frequency range of the Nancay Radioheliograph.

TL;DR: In this paper, the authors investigate the source height of chromospheric footpoints in white light (WL) and hard X-rays (HXR) and find the WL and HXR (?30 keV) centroids to be largely co-spatial and from similar heights for all events, with altitudes around 800 km above the photosphere or 300?450 km above a limb height.

TL;DR: In this article, the authors compare radio images of high-energy electrons accelerated by a solar flare and images of hard X-rays produced by the same electrons at photon energies above 100 keV.
