Spatially Resolved Ultraviolet Spectra of the High-Velocity Nuclear Outflow of NGC 1068
arXiv:astro-ph/0407007 · doi:10.1086/422249
Abstract
We present ultraviolet emission-line maps of the narrow-line region (NLR) of NGC 1068. The maps span 115--318 nm, the biconical ionization cone, several posited jet/ISM interactions, and the compact knots whose optical spectra we reported previously resemble kinematically the quasar Associated Absorption Line systems. Across the NLR, we find that ultraviolet flux ratios are consistent with photoionization, not shock excitation, even for gas blueshifted abruptly to 3000 \kms relative to galaxy systemic velocity or for gas projected near the radio jet. The knots may be radiatively accelerated, photoablated fragments of molecular clouds.
