Benchmark Test of Differential Emission Measure Codes and Multi-Thermal Energies in Solar Active Regions
M. J. Aschwanden, P. Boerner, A. Caspi +3
We compare the ability of 11 Differential Emission Measure (DEM) forward-fitting and inversion methods to constrain the properties of active regions and solar flares by simulating…
Thermal Diagnostics with the Atmospheric Imaging Assembly onboard the Solar Dynamics Observatory: A Validated Method for Differential Emission Measure Inversions
Mark C. M. Cheung, P. Boerner, C. J. Schrijver +4
We present a new method for performing differential emission measure (DEM) inversions on narrow-band EUV images from the Atmospheric Imaging Assembly (AIA) onboard the Solar Dynami…
Global Energetics of Solar Flares: II. Thermal Energies
M. J. Aschwanden, P. Boerner, D. Ryan +3
We present the second part of a project on the global energetics of solar flares and CMEs that includes about 400 M- and X-class flares observed with AIA/SDO during the first 3.5 y…
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…
Homologous Helical Jets: Observations by IRIS, SDO and Hinode and Magnetic Modeling with Data-Driven Simulations
Mark C. M. Cheung, B. De Pontieu, T. D. Tarbell +18
We report on observations of recurrent jets by instruments onboard the Interface Region Imaging Spectrograph (IRIS), Solar Dynamics Observatory (SDO) and Hinode spacecrafts. Over a…
