Description

It is found that NGC 5548 contains a spatially extended high-excitation narrow-line region with line widths ranging between 500 and 100 km/s (FWHM). This nebulosity is elongated along the axis of the triple radio source. The peak of optical continuum light (nucleus) coincides with the peak of the forbidden O III 5007 A distribution. 64 refs
