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…
The Spectral Energy Distribution of the Seyfert galaxy Ton S180
T. J. Turner, P. Romano, S. B. Kraemer +14
We present spectral results from a multi-satellite, broad-band campaign on the Narrow-line Seyfert 1 galaxy Ton S180 performed at the end of 1999. We discuss the spectral-energy di…
On the Nature of Intrinsic Absorption in Reddened Seyfert 1 Galaxies
D. M. Crenshaw, S. B. Kraemer
We discuss the origin of the ``dusty lukewarm absorber'', which we previously identified in the reddened Seyfert 1 galaxies NGC 3227 and Akn 564. This absorber is characterized by…
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…
HST STIS Observations of PG 0946+301: the Highest Quality UV Spectrum of a BALQSO
Nahum Arav, Martijn de Kool, Kirk T. Korista +16
We describe deep (40 orbits) HST/STIS observations of the BALQSO PG 0946+301 and make them available to the community. These observations are the major part of a multi-wavelength c…
