First NuSTAR Limits on Quiet Sun Hard X-Ray Transient Events
Andrew J. Marsh, David M. Smith, Lindsay Glesener +16
We present the first results of a search for transient hard X-ray (HXR) emission in the quiet solar corona with the \textit{Nuclear Spectroscopic Telescope Array} (\textit{NuSTAR})…
Evidence of Significant Energy Input in the Late Phase of a Solar Flare from NuSTAR X-Ray Observations
Matej Kuhar, Säm Krucker, Iain G. Hannah +15
We present observations of the occulted active region AR12222 during the third {\em NuSTAR} solar campaign on 2014 December 11, with concurrent {\em SDO/}AIA and {\em FOXSI-2} soun…
The First Focused Hard X-ray Images of the Sun with NuSTAR
Brian W. Grefenstette, Lindsay Glesener, Säm Krucker +20
We present results from the the first campaign of dedicated solar observations undertaken by the \textit{Nuclear Spectroscopic Telescope ARray} ({\em NuSTAR}) hard X-ray telescope.…
The first X-ray imaging spectroscopy of quiescent solar active regions with NuSTAR
I. G. Hannah, B. W. Grefenstette, D. M. Smith +15
We present the first observations of quiescent active regions (ARs) using NuSTAR, a focusing hard X-ray telescope capable of studying faint solar emission from high temperature and…
NuSTAR and Swift observations of the fast rotating magnetized white dwarf AE Aquarii
Takao Kitaguchi, Hongjun An, Andrei M. Beloborodov +11
AE Aquarii is a cataclysmic variable with the fastest known rotating magnetized white dwarf (P_spin = 33.08 s). Compared to many intermediate polars, AE Aquarii shows a soft X-ray…
