THE X-RAY-EMISSION OF NGC-1068

This paper summarises the X-ray properties of NGC 1068 from the observ ers perspective and reports new observations with the ROSAT HRI. Below similar or equal to 2 keV, the spectrum is steep and probably represe nts thermal emission from gas with temperature kT similar or equal to 0.1 - 0.6 keV. Above similar or equal to 2 keV, the spectrum is much f latter and may be described by a power-law with energy index alpha sim ilar or equal to 0.3. Images with the ROSAT HRI reveal that about half the X-ray flux in the 0.1 - 2.4 keV band is extended on scales > 5 '' (360 pc). Recent ROSAT PSPC observations of starburst galaxies show i ntegrated soft X-ray spectra which are very similar to that of NGC 106 8 below 2 keV. The spatially extended, steep, soft X-ray emission of N GC 1068 probably originates through thermal emission from a hot wind d riven by the disk starburst, the Seyfert nucleus or a combination of t he two. On the other hand, the hard emission above 2 keV is almost cer tainly dominated by the Seyfert nucleus.
