Multi-component Decomposition of Astronomical Spectra by Compressed Sensing
Mark C. M. Cheung, Bart De Pontieu, Juan Martınez-Sykora +9
The signal measured by an astronomical spectrometer may be due to radiation from a multi-component mixture of plasmas with a range of physical properties (e.g. temperature, Doppler…
Internetwork chromospheric bright grains observed with IRIS
Juan Martínez-Sykora, Luc Rouppe van der Voort, Mats Carlsson +18
The Interface Region Imaging Spectrograph (IRIS) reveals small-scale rapid brightenings in the form of bright grains all over coronal holes and the quiet sun. These bright grains a…
Soft X-ray Fluxes of Major Flares Far Behind the Limb as Estimated Using STEREO EUV Images
N. V. Nitta, M. J. Aschwanden, P. F. Boerner +3
With increasing solar activity since 2010, many flares from the backside of the Sun have been observed by the Extreme Ultraviolet Imager (EUVI) on either of the twin STEREO spacecr…
First 3D Reconstructions of Coronal Loops with the STEREO A+B Spacecraft: IV. Magnetic Modeling with Twisted Force-Free Fields
Markus J. Aschwanden, Jean-Pierre Wuelser, Nariaki V. Nitta +3
The three-dimensional (3D) coordinates of stereoscopically triangulated loops provide strong constraints for magnetic field models of active regions in the solar corona. Here we us…
First Stereoscopic Coronal Loop Reconstructions from Stereo Secchi Images
L. Feng, B. Inhester, S. K. Solanki +4
We present the first reconstruction of the three-dimensional shape of magnetic loops in an active region from two different vantage points based on simultaneously recorded images.…
