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…
The Advanced Compton Telescope Mission
Steven E. Boggs, James Kurfess, James Ryan +30
The Advanced Compton Telescope (ACT), the next major step in gamma-ray astronomy, will probe the fires where chemical elements are formed by enabling high-resolution spectroscopy o…
Supernovae and Positron Annihilation
P. A. Milne, J. D. Kurfess, R. L. Kinzer +1
Radioactive nuclei, especially those created in SN explosion, have long been suggested to be important contributors of galactic positrons. In this paper we describe the findings of…
Advanced Compton Telescope Designs and SN Science
P. A. Milne, R. A. Kroeger, J. D. Kurfess +1
The Advanced Compton Telescope (ACT) has been suggested to be the optimal next-generation instrument to study nuclear gamma-ray lines. In this work, we investigate the potential of…
Comparative Studies of Line and Continuum Positron Annihilation Radiation
P. A. Milne, J. D. Kurfess, R. L. Kinzer +1
Positron annihilation radiation from the Galaxy has been observed by the OSSE, SMM and TGRS instruments. Improved spectral modeling of OSSE observations has allowed studies of the…
Investigations of Positron Annihilation Radiation
P. A. Milne, J. D. Kurfess, R. L. Kinzer +2
By combining OSSE, SMM and TGRS observations of the galactic center region, Purcell et al. (1997) and Cheng et al. (1997) produced the first maps of galactic positron annihilation.…
