IUE evidence on the nature of the innermost broad-line region in Seyfert 1 galaxies

OSTI ID:7088656
The continuum level at 1550 A was obtained for most of the International Ultraviolet Explorer (IUE) images available for the Seyfert 1 galaxies NGC4151, NGC5548, and Fairall 9 (F9). Major features of the IUE spectra of these three objects, and especially the C IV lambda 1550 emission (whose emission profiles imply radial motion of the emitting carbon ions at velocities approaching 15,000 km/sec), appear to be consistent with the general picture of a fast, thick, radial outflow from a hot, starlike surface, and with approximately spherical symmetry. A supermassive star appears to be a good candidate for the central power source in these objects.
