TeV and Multi-wavelength Observations of Mrk 421 in 2006-2008
V. A. Acciari, E. Aliu, T. Arlen +103
We report on TeV gamma-ray observations of the blazar Mrk 421 (redshift of 0.031) with the VERITAS observatory and the Whipple 10m Cherenkov telescope. The excellent sensitivity of…
Using the Active Collimator and Shield Assembly of an EXIST-Type Mission as a Gamma-Ray Burst Spectrometer
A. Garson, H. Krawczynski, J. Grindlay +2
The Energetic X-ray Imaging Survey Telescope (EXIST) is a mission design concept that uses coded masks seen by Cadmium Zinc Telluride (CZT) detectors to register hard X-rays in the…
CZT in Space Based Hard-X-ray Astronomy
A. Garson, H. Krawczynski, G. Weidenspointner +4
One of the key aspects of a detector material for space-borne hard X-ray and gamma-ray telescopes is the rate of prompt and delayed background events generated inside the material…
EXIST's Gamma-Ray Burst Sensitivity
D. L. Band, J. E. Grindlay, J. Hong +7
We use semi-analytic techniques to evaluate the burst sensitivity of designs for the EXIST hard X-ray survey mission. Applying these techniques to the mission design proposed for t…
HX-POL - A Balloon-Borne Hard X-Ray Polarimeter
H. Krawczynski, A. Garson, Q. Li +10
We report on the design and estimated performance of a balloon-borne hard X-ray polarimeter called HX-POL. The experiment uses a combination of Si and Cadmium Zinc Telluride detect…
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…
