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…
Timing Calibration of the NuSTAR X-ray Telescope
Matteo Bachetti, Craig B. Markwardt, Brian W. Grefenstette +13
The Nuclear Spectroscopic Telescope Array (NuSTAR) mission is the first focusing X-ray telescope in the hard X-ray (3-79 keV) band. Among the phenomena that can be studied in this…
NuSTAR low energy effective area correction due to thermal blanket tear
Kristin K. Madsen, Brian W. Grefenstette, Sean Pike +4
A rip in the MLI at the exit aperture of OMA, the NuSTAR optic aligned with detector focal plane module FPMA, has resulted in an increased photon flux through OMA that has manifest…
NuSTAR observations of G11.2-0.3
K. K. Madsen, C. L. Fryer, B. W. Grefenstette +3
We present in this paper the hard X-ray view of the pulsar wind nebula in G11.2-0.3 and its central pulsar PSR J1811-1925 as seen by NuSTAR. We complement the data with Chandra for…
Summary of the 14th IACHEC Meeting
K. K. Madsen, Y. Terada, V. Burwitz +8
We summarize the 14th meeting of the International Astronomical Consortium for High Energy Calibration (IACHEC) held at \textit{Shonan Village} (Kanagawa, Japan) in May 2019. Sixty…
