FOXSI-2 Solar Microflares II: Hard X-ray Imaging Spectroscopy and Flare Energetics
Juliana T. Vievering, Lindsay Glesener, P. S. Athiray +7
We study the nature of energy release and transfer for two sub-A class solar microflares observed during the second flight of the Focusing Optics X-ray Solar Imager (FOXSI-2) sound…
Use of a ray-tracing simulation to characterize ghost rays in the FOXSI rocket experiment
J. C. Buitrago-Casas, S. Christe, L. Glesener +12
Imaging X-rays by direct focusing offers greater sensitivity and a higher dynamic range compared to techniques based on indirect imaging. The Focusing Optics X-ray Solar Imager (FO…
FOXSI-2 Solar Microflares I : Multi-instrument Differential Emission Measure Analysis and Thermal Energies
P. S. Athiray, Juliana Vievering, Lindsay Glesener +8
In this paper we present the differential emission measures (DEMs) of two sub-A class microflares observed in hard X-rays (HXRs) by the FOXSI-2 sounding rocket experiment, on 2014…
Solar Active Region Heating Diagnostics from High Temperature Emission using the Marshall Grazing Incidence X-ray Spectrometer (MaGIXS)
P. S. Athiray, Amy R. Winebarger, Will T. Barnes +7
The relative amount of high temperature plasma has been found to be a useful diagnostic to determine the frequency of coronal heating on sub-resolution structures. When the loops a…
Modeling charge transport in Swept Charge Devices for X-ray spectroscopy
P. S. Athiray, S. Narendranath, P. Sreekumar +3
We present the formulation of an analytical model which simulates charge transport in Swept Charge Devices (SCDs) to understand the nature of the spectral redistribution function (…
