The formation of IRIS diagnostics. III. Near-ultraviolet Spectra and Images
Tiago M. D. Pereira, Jorrit Leenaarts, Bart De Pontieu +2
The Mg II h&k lines are the prime chromospheric diagnostics of NASA's Interface Region Imaging Spectrograph (IRIS). In the previous papers of this series we used a realistic three-…
Optimization of Curvi-Linear Tracing Applied to Solar Physics and Biophysics
Markus J. Aschwanden, Bart De Pontieu, Eugene A. Katrukha
We developed an automated pattern recognition code that is particularly well suited to extract one-dimensional curvi-linear features from two-dimensional digital images. A former v…
The formation of IRIS diagnostics II. The formation of the Mg II h&k lines in the solar atmosphere
J. Leenaarts, T. M. D. Pereira, M. Carlsson +2
NASA's Interface Region Imaging Spectrograph (IRIS) small explorer mission will study how the solar atmosphere is energized. IRIS contains an imaging spectrograph that covers the M…
The formation of IRIS diagnostics I. A quintessential model atom of Mg II and general formation properties of the Mg II h&k lines
J. Leenaarts, T. M. D. Pereira, M. Carlsson +2
NASA's Interface Region Imaging Spectrograph (IRIS) space mission will study how the solar atmosphere is energized. IRIS contains an imaging spectrograph that covers the Mg II h&k…
A Detailed Comparison Between The Observed and Synthesized Properties of a Simulated Type ii Spicule
Juan Martinez-Sykora, Bart De Pontieu, Jorrit Leenaarts +7
We performed a 3D radiative MHD simulation of the solar atmosphere. This simulation shows a jet-like feature that shows similarities to the type II spicules observed for the first…
Observing coronal nanoflares in active region moss
Paola Testa, Bart De Pontieu, Juan Martinez-Sykora +12
The High-resolution Coronal Imager (Hi-C) has provided Fe XII 193A images of the upper transition region moss at an unprecedented spatial (~0.3-0.4 arcsec) and temporal (5.5s) reso…
