First Point-Spread Function and X-Ray Phase-Contrast Imaging Results With an 88-mm Diameter Single Crystal
A. H. Lumpkin, A. B. Garson, M. A. Anastasio
In this study, we report initial demonstrations of the use of single crystals in indirect x-ray imaging with a benchtop implementation of propagation-based (PB) x-ray phase contras…
Optimization of the Design of the Hard X-ray Polarimeter X-Calibur
Qingzhen Guo, Matthias Beilicke, Alfred Garson +3
We report on the optimization of the hard X-ray polarimeter X-Calibur for a high-altitude balloon-flight in the focal plane of the InFOCμS X-ray telescope from Fort Sumner (NM) in…
Study of Thick CZT Detectors for X-ray and Gamma-Ray Astronomy
Qiang Li, M. Beilicke, Kuen Lee +8
CdZnTe (CZT) is a wide bandgap II-VI semiconductor developed for the spectroscopic detection of X-rays and γ-rays at room temperature. The Swift Burst Alert Telescope is using an 5…
Design of a Hard X-ray Polarimeter: X-Calibur
Qingzhen Guo, Alfred Garson, Matthias Beilicke +3
We report on Monte Carlo studies of the hard X-ray polarimeter X-Calibur. The polarimeter will be used in the focal plane of a grazing incidence hard X-ray telescope. It combines a…
Scientific Prospects for Hard X-ray Polarimetry
H. Krawczynski, A. Garson, Q. Guo +4
X-ray polarimetry promises to give qualitatively new information about high-energy sources. Examples of interesting source classes are binary black hole systems, rotation and accre…
A Suzaku X-Ray Study of the Particle Acceleration Processes in the Relativistic Jet of Blazar Mrk 421
Alfred B. Garson, Matthew G. Baring, Henric Krawczynski
We report on the findings of a 364 ksec observation of the BL LAC object Mrk 421 with the X-ray observatory Suzaku. The analysis in this paper uses fluxes and hardness ratios in th…
