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.…
Comment on ``An iterative method of imaging''
D. D. Dixon
Image processing is an increasingly important aspect for analysis of data from X and -ray astrophysics missions. In this paper, I review a method proposed by Kebede (L. W. Kebed…
Evidence for GeV emission from the Galactic Center Fountain
D. H. Hartmann, D. D. Dixon, E. D. Kolaczyk +1
The region near the Galactic center may have experienced recurrent episodes of injection of energy in excess of 10 ergs due to repeated starbursts involving more than…
Skymapping with OSSE via the Mean Field Annealing Pixon Technique
D. D. Dixon, T. O. Tumer, A. D. Zych +7
We present progress toward using scanned OSSE observations for mapping and sky survey work. To this end, we have developed a technique for detecting pointlike sources of unknown nu…
Detection of Atmospheric Cherenkov Radiation Using Solar Heliostat Mirrors
Rene A. Ong, the STACEE Collaboration
The gamma-ray energy region between 20 and 250 GeV is largely unexplored. Ground-based atmospheric Cherenkov detectors offer a possible way to explore this region, but large Cheren…
