International Astrophysical Consortium for High-energy Calibration: Summary of the 15th IACHEC Workshop
K. K. Madsen, V. Burwitz, K. Forster +8
In this report, we summarize the activities of the International Astronomical Consortium for High Energy Calibration (IACHEC) from the 15th IACHEC Workshop in Pelham, Germany. Sixt…
Measuring the Evolution of the NuSTAR Detector Gains
Brian Grefenstette, Murray Brightman, Hannah P. Earnshaw +3
The memo describes the methods used to track the long-term gain variations in the NuSTAR detectors. It builds on the analysis presented in Madsen et al. (2015) using the deployable…
Reconstruction of the NuSTAR point spread function using single-laser metrology
Hannah P. Earnshaw, Kristin K. Madsen, Karl Forster +4
This paper describes a method by which the metrology system of the Nuclear Spectroscopic Telescope Array (NuSTAR) X-ray space observatory, which uses two lasers to characterize the…

K. K. Madsen, V. Burwitz, K. Forster +8
In this report we summarize the activities of the International Astronomical Consortium for High Energy Calibration (IACHEC) and the work done since the last in-person meeting in J…
2021 Effective Area calibration of the Nuclear Spectroscopic Telescope ARray (NuSTAR)
Kristin K. Madsen, Karl Forster, Brian W. Grefenstette +2
We present here the updated calibration of The Nuclear Spectroscopic Telescope ARray NuSTAR, which was performed using data on the Crab accumulated over the last 9 years in orbit.…
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…
