Probing the Kinematics of the Narrow-Line Region in Seyfert Galaxies with Slitless Spectroscopy: Observational Results
J. R. Ruiz, D. M. Crenshaw, S. B. Kraemer +5
We present slitless spectra of 10 Seyfert galaxies observed with the Space Telescope Imaging Spectrograph on the Hubble Space Telescope. The spectra cover the [OIII] 4959, 5007 emi…
Physical Conditions in the Narrow-Line Region of Markarian 3. I. Observational Results
Nicholas R. Collins, Steven B. Kraemer, D. Michael Crenshaw +3
We use Hubble Space Telescope/Space Telescope Imaging Spectrograph (HST/STIS) longslit low-resolution spectroscopy from 1150A to 10,300A to study the physical conditions in the nar…
Constraints on Intrinsic UV Absorption in NGC 3783
Jack R. Gabel, Steven B. Kraemer, D. Michael Crenshaw
Results from an analysis of the intrinsic UV absorption in the Seyfert 1 galaxy NGC 3783 are presented. We focus on two new results that demonstrate techniques for deriving importa…
High-Resolution Ultraviolet Spectra of the Dwarf Seyfert 1 Galaxy NGC 4395: Evidence for Intrinsic Absorption
D. M. Crenshaw, S. B. Kraemer, J. R. Gabel +5
We present ultraviolet spectra of the dwarf Seyfert 1 nucleus of NGC 4395, obtained with the Far Ultraviolet Spectroscopic Explorer (FUSE) and the Hubble Space Telescope's Space Te…
Simultaneous X-ray and Ultraviolet spectroscopy of the Seyfert galaxy NGC 5548. III. X-ray time variability
J. S. Kaastra, K. C. Steenbrugge, D. M. Crenshaw +8
The Seyfert 1 galaxy NGC 5548 was observed for a week by Chandra using both the HETGS and LETGS spectrometers. In this paper we study the time variability of the continuum radiatio…
On the Relationship Between the Optical Emission-Line and X-ray Luminosities in Seyfert 1 Galaxies
S. B. Kraemer, I. M. George, D. M. Crenshaw +1
We have explored the relationship between the [O III] 5007 and the 2--10 keV luminosities for a sample of Broad- and Narrow-Line Seyfert 1 galaxies (BLSy1 and NLSy1, respectivel…
