Near-ultraviolet Spectropolarimetry as a Tracer of Magnetic Markers of Flux Rope Formation
The Astrophysical JournalWe investigate the suitability of the combined spectral windows of Mg ii h and k and the Fe ii lines around 261 nm as magnetic markers of filament formation.

Structure of sunspot light bridges in the chromosphere and transition region
, 2017 Light bridges (LBs) are elongated structures with enhanced intensity embedded in sunspot umbra and pores. We studied the properties of a sample of 60 LBs observed with the Interface Region Imaging Spectrograph (IRIS). Using IRIS near- and far-ultraviolet

Solar Flare Ribbon Fronts. II. Evolution of Heating Rates in Individual Flare Footpoints
The Astrophysical JournalSolar flare ribbon fronts appear ahead of the bright structures that normally characterize solar flares, and can persist for an extended period of time in spatially localized patches before transitioning to “regular” bright ribbons. They likely represent
