Faint Object Spectrograph Spectroscopy of Resolved Structure in the Nucleus of NGC 1068
Abstract
We report the results of FOS spectroscopy of the continuum peak of NGC 1068 in the wavelength range 2200-7000 A. Detailed analysis reveals the emission lines to be complex in shape and to consist of a number of different velocity components. Both the Balmer lines and the strong forbidden lines have a contribution from a component with full width at half-maximum on the order of 2200 km s^-1^. However, we do not detect the broad Hβ emission observed in polarized light. This implies that the continuum peak is not the mirror which reflects light from the hidden Seyfert 1 nucleus. It could possibly contribute some of the reflected light, but the equivalent width of the Hβ BLR line, if present at all, is much weaker than expected from the ground-based nuclear polarized-flux spectrum.
