A ROSAT high resolution X-ray image of NGC 1068
Abstract
The soft X-ray properties of the Seyfert 2 galaxy NGC 1068 are a crucial test of the ``hidden Seyfert 1'' model. It is important to determine whether the soft X-rays come from the nucleus, or from a number of other possible regions in the circumnuclear starburst disk. We present preliminary results of a ROSAT HRI observation of NGC 1068 obtained during the verification phase. The fraction of X-rays that can be attributed to the nuclues is about 70%, so the ``soft X-ray problem'' remains. There is also significant diffuse X-ray flux on arcminute scales, which may be related to the ``diffuse ionized medium'' seen in optical emission lines, and the highly ionized Fe Kα emission seen by BBXRT.
