Resolved Ultraviolet Spectra of the High - Velocity Nuclear Outflow of NGC 1068
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 photo...
متن کاملISO - SWS spectroscopy of NGC 1068
We present ISO-SWS spectroscopy of NGC 1068 for the complete wavelength range 2.4 to 45μm at resolving power ∼1500. Selected subranges have been observed at higher sensitivity and full resolving power ∼2000. We detect a total of 36 emission lines and derive upper limits for 13 additional transitions. Most of the observed transitions are fine structure and recombination lines originating in the ...

متن کاملKinematics of the narrow - line region of NGC 1068 ?
We investigated the kinematics of the Narrow Line Region of NGC 1068. In order to study the kinematics and to determine whether the unusual broad line width can be attributed to motion of NLR clouds in a deep gravitational potential or to expanding shocks, we carried out spatially resolved echelle spectroscopy. High spectral resolution enables the identification of individual clouds in long sli...
متن کاملSPECTROPOLARIMETRY OF THE 3.4 m ABSORPTION FEATURE IN NGC 1068
In order to test the silicate-core/organic-mantle model of galactic interstellar dust, we have performed spectropolarimetry of the 3.4 mC H bond stretch that is characteristic of aliphatic hydrocarbons, using the nucleus of the Seyfert 2 galaxy, NGC 1068, as a bright, dusty background source. Polarization calculations show that if the grains in NGC 1068 had the properties assigned by the core-m...
