Abstract

FUSE Spectra of the nuclear region of NGC 1068 find strong OVI emission consisting of a pair of narrow and broad components. There is a gradient in the velocity field for the narrow O V I component of ∼ 200 kms- 1 from ∼ 2" southwest of the nucleus to ∼ 4" northeast. A similar pattern is also observed with the broad O V I component, with a gradient of ∼ 3000 kms- 1. These results are consistent with the HST/STIS findings and suggest a biconical structure in which the velocity field is mainly radial outflow.
