Line Spread Functions of Blazed Off-Plane Gratings Operated in the Littrow Mounting
Casey T. DeRoo, Randall L. McEntaffer, Drew M. Miles +13
Future soft X-ray (10 - 50 Angstrom) spectroscopy missions require higher effective areas and resolutions to perform critical science that cannot be done by instruments on current…
Performance Testing of a Novel Off-plane Reflection Grating and Silicon Pore Optic Spectrograph at PANTER
Hannah Marlowe, Randall L. McEntaffer, Ryan Allured +12
An X-ray spectrograph consisting of radially ruled off-plane reflection gratings and silicon pore optics was tested at the Max Planck Institute for extraterrestrial Physics PANTER…
Analytical Alignment Tolerances for Off-Plane Reflection Grating Spectroscopy
Ryan Allured, Randall L. McEntaffer
Future NASA X-ray Observatories will shed light on a variety of high-energy astrophysical phenomena. Off-plane reflection gratings can be used to provide high throughput and spectr…
Swift and RXTE observations of the black hole transient GX 339-4 in the hard state between outbursts
Ryan Allured, John A. Tomsick, Philip Kaaret +1
We use simultaneous Swift and RXTE observations of the black hole binary GX 339-4 to measure the inner radius of its accretion disk in the hard state down to 0.4% L_{Edd} via model…
A Soft X-ray Beam-splitting Multilayer Optic for the NASA GEMS Bragg Reflection Polarimeter
Ryan Allured, Monica Fernandez-Perea, Regina Soufli +4
A soft X-ray, beam-splitting, multilayer optic has been developed for the Bragg Reflection Polarimeter (BRP) on the NASA Gravity and Extreme Magnetism Small Explorer Mission (GEMS)…
Combined Spectral and Timing Analysis of the Black Hole Candidate MAXI J1659-152 Discovered by MAXI and Swift
Kazutaka Yamaoka, Ryan Allured, Philip Kaaret +12
We report on X-ray spectral and timing results of the new black hole candidate (BHC) MAXI J1659-152 with the orbital period of 2.41 hours (shortest among BHCs) in the 2010 outburst…
