| Abstract: |
We report the cold matter distribution in the Galactic Center region. We have measured the column density of X-ray binaries in the Galactic Center using the X-ray satellite ASCA, and derive the total mass and distribution of cold matter in this region. The column densities are given by a smooth function of angular distance from the Galactic Plane. Assuming a disk-like mass distribution with 500 pc radius, we estimate the total mass to be (1--several) times 107 Modot. Together with results at other wavelengths, we discuss the physical conditions of the cold matter in the Galactic Center region. |
