The Detection of Circumnuclear X-ray Emission from the Seyfert Galaxy NGC 3516
I. M. George, T. J. Turner, H. Netzer +7
We present the first high-resolution, X-ray image of the circumnuclear regions of the Seyfert 1 galaxy NGC 3516, using the Chandra X-ray Observatory (CXO). All three of the CXO obs…
Reddening, Emission-Line, and Intrinsic Absorption Properties in the Narrow-Line Seyfert 1 Galaxy Akn 564
D. M. Crenshaw, S. B. Kraemer, T. J. Turner +14
We use Hubble Space Telescope UV and optical spectra of the narrow-line Seyfert 1 (NLS1) galaxy Akn 564 to investigate its internal reddening and properties of its emission-line an…
Kinematics of the Narrow-Line Region in the Seyfert 2 Galaxy Mrk 3
Jose R. Ruiz, D. M. Crenshaw, S. B. Kraemer +5
We present measurements of radial velocities for the narrow-line region gas (NLR) in the Seyfert 2 galaxy Mrk 3 out to ~1 kpc from the nucleus. The observations consist of two data…
The X-ray Emission from the Nucleus of the Dwarf Elliptical Galaxy NGC 3226
I. M. George, R. F. Mushotzky, T. Yaqoob +6
We present the first high resolution X-ray image of the dwarf elliptical galaxy NGC 3226. The data were obtained during an observation of the nearby Seyfert Galaxy NGC 3227 using t…
High-Resolution X-ray and Ultraviolet Spectroscopy of the Complex Intrinsic Absorption in NGC 4051 with Chandra and HST
M. J. Collinge, W. N. Brandt, Shai Kaspi +6
We present the results from simultaneous observations of the Narrow-Line Seyfert 1 galaxy NGC 4051 with the Chandra High Energy Transmission Grating Spectrometer and the HST Space…
STIS Echelle Observations of the Seyfert Galaxy NGC 4151: Physical Conditions in the Ultraviolet Absorbers
S. B. Kraemer, D. M. Crenshaw, J. B. Hutchings +6
We have examined the physical conditions in intrinsic UV-absorbing gas in the Seyfert galaxy NGC 4151, using echelle spectra obtained with the Space Telescope Imaging Spectrograph…
