Resolved Spectra of the Narrow-Line Region in NGC 1068. III. Physical Conditions in the Emission-Line Gas
Steven B. Kraemer, D. Michael Crenshaw
The physical conditions in the inner narrow line region (NLR) of the Seyfert 2 galaxy NGC 1068 are examined using HST/STIS ultraviolet and optical spectra and photoionization model…
A Kinematic Model for the Narrow-Line Region in NGC 4151
D. M. Crenshaw, S. B. Kraemer, J. B. Hutchings +6
We present a simple kinematic model for the narrow-line region (NLR) of the Seyfert 1 galaxy NGC 4151, based on our previous observations of extended [O III] emission with the Spac…
Resolved Spectroscopy of the Narrow-Line Region in NGC 1068: Kinematics of the Ionized Gas
D. M. Crenshaw, S. B. Kraemer
We have determined the radial velocities of the [O III] emitting gas in the inner narrow-line region (NLR) of the Seyfert 2 galaxy NGC 1068, along a slit at position angle of 202 d…
On The Reddening in X-ray Absorbed Seyfert 1 Galaxies
S. B. Kraemer, I. M. George, T. J. Turner +1
There are several Seyfert galaxies for which there is a discrepancy between the small column of neutral hydrogen deduced from X-ray observations and the much greater column derived…
HST Observations and Photoionization Modeling of the LINER Galaxy NGC 1052
J. R. Gabel, F. C. Bruhweiler, D. M. Crenshaw +2
We present a study of available Hubble Space Telescope (HST) spectroscopic and imaging observations of the low ionization nuclear emission line region (LINER) galaxy NGC 1052. The…
