A High Energy X-Ray Study of the Galactic Center.

Abstract

In this project I have studied the characteristics of the high-energy X-ray sources within 20 deg of the center of the Milky Way Galaxy. The major aim was to obtain an acceptable fit to data from the UCSD/MIT Hard X-ray and Low Energy Gamma-Ray experiment on HEAO-1. In this manner, I could study the spectra, positions and time-variability of about 25 sources. The major results of this project are the following. (1) Most of the sources have steeply falling spectra as expected. (2) An intense, hard source exists within 0.5 deg of the galactic center, and it has a two-component spectrum can be extrapolated to higher energy at the intensity of the gamma-ray continuum, which implies that this continuum is a composite of a number of sources.
