TRANSIENTS IN THE GALACTIC CENTER REGION


ABSTRACT

We propose the observations of transient X-ray sources in the Galactic Center region. In this region we have discovered the diffuse 6.4-keV line component, which is considered as the fluorescent K-alpha line from neutral iron. It should be the good tracer for hidden high energy activity in the region. However, the origin has not been understood, yet. If the transients in this region preserved the brightness for a few years, they would give significant contribution to the 6.4-keV intensity. In addition, using their column densities, we can derive the column density distribution more exactly where the statistics critically lacks at present. The exact column density distribution is essential to investigate the origin of 6.4-keV line distribution.
