Far Ultraviolet Spectroscopic Explorer Observations of the Seyfert 1.5 Galaxy NGC 5548 in a Low State
M. S. Brotherton, R. F. Green, G. A. Kriss +4
We present far-ultraviolet spectra of the Seyfert 1.5 galaxy NGC 5548 obtained in 2000 June with the Far Ultraviolet Spectroscopic Explorer (FUSE). Our data span the observed wavel…
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…
Ultraviolet Broad Absorption Features and the Spectral Energy Distribution of the QSO PG 1351+64
W. Zheng, G. A. Kriss, J. X. Wang +7
We present a moderate-resolution (~20 km/s) spectrum of the mini broad-absorption-line QSO PG1351+64 between 915-1180 A, obtained with the Far Ultraviolet Spectroscopic Explorer (F…
M33: A Galaxy with No Supermassive Black Hole
Karl Gebhardt, Tod R. Lauer, John Kormendy +9
Galaxies that contain bulges appear to contain central black holes whose masses correlate with the velocity dispersion of the bulge. We show that no corresponding relationship appl…
Evidence for an accelerating wind as the broad-line region in NGC 3516
J. B. Hutchings, G. A. Kriss, R. F. Green +4
Spectroscopic data in wavelengths 900--3000A have been obtained in a low flux state of the nucleus of the Seyfert 1 galaxy NGC 3516. The line profiles show P Cygni characteristics,…
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…
