Studying the Variable Continuum and Emission Line Spectrum of 4U 1700-377 using NuSTAR's Stray Light
Colin J Bourque, McKinley C Brumback, Brian W Grefenstette +4
The high-mass X-ray binary 4U 1700-377 shows strong variation in brightness on timescales of hundreds of seconds due to accretion from a highly clumped stellar wind from the compan…
NuSTAR's Intentional Stray Light Observation of Scorpious X-1
S. Li, R. M. Ludlam, M. Sudha +8
We present the first spectral analysis of Scorpius X-1 (Sco X-1) using intentional stray light (SL) observations taken by NuSTAR. Unlike focused observations that have high telemet…
The NuSTAR View of Perseus: the ICM and a Peculiar Hard Excess
Samantha Creech, Daniel R. Wik, Steven Rossland +3
As the brightest galaxy cluster in the X-ray sky, Perseus is an excellent target for studying the Intracluster Medium (ICM), but until recently, its active galactic nucleus (AGN) m…
Measuring the Cosmic X-ray Background in 3-20keV with Straylight from NuSTAR
Steven Rossland, Daniel Wik, Brian Grefenstette +13
By characterizing the contribution of stray light to large datasets from the NuSTAR X-ray observatory collected over 2012--2017, we report a measurement of the cosmic X-ray backgro…
Long-Exposure NuSTAR Constraints on Decaying Dark Matter in the Galactic Halo
Brandon M. Roach, Steven Rossland, Kenny C. Y. Ng +6
We present two complementary NuSTAR x-ray searches for keV-scale dark matter decaying to mono-energetic photons in the Milky Way halo. In the first, we utilize the known intensity…
NuSTAR measurement of the cosmic X-ray background in the 3-20 keV energy band
Roman Krivonos, Daniel Wik, Brian Grefenstette +5
We present measurements of the intensity of the Cosmic X-ray Background (CXB) with the NuSTAR telescope in the 3-20 keV energy range. Our method uses spatial modulation of the CXB…
