The Importance of Shocks in the Ionization of the Narrow Line Region of Seyferts
H. R. Schmitt, A. L. Kinney, J. B. Hutchings +2
We discuss the viability of shocks as the principal source of ionization for the Narrow Line Region of Seyfert galaxies. We present the preliminary results of [OIII]5007A and radio…
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…
Resolving the Structure of Ionized Helium in the Intergalactic Medium with the Far Ultraviolet Spectroscopic Explorer
G. A. Kriss, J. M. Shull, W. Oegerle +16
The neutral hydrogen and the ionized helium absorption in the spectra of quasars are unique probes of structure in the early universe. We present Far-Ultraviolet Spectroscopic Expl…
900-1200A interstellar extinction in the Galaxy, LMC, and SMC
J. B. Hutchings, J. Giasson
We have derived far-ultraviolet extinction curves for stars in the Galaxy, LMC, and SMC, from spectra of pairs of stars observed with the FUSE satellite, matched in spectral type a…
QSO hosts and companions at higher redshifts
J. B. Hutchings
This review presents the current state of work on QSO hosts and companions at redshifts above 1. This includes the properties of QSO host galaxies, such as size, scale length, and…
Far-UV Observations of the Galactic Supersoft Binary RXJ0019.8+2156 (QR And)
J. B. Hutchings, D. Crampton, A. P. Cowley +2
FUSE spectra were obtained of the supersoft X-ray binary RX J0019.8+2156 (QR And) during 16 consecutive spacecraft orbits, covering the binary orbit (P=15.85 hr) with about 0.2 pha…
A Pair of Compact Red Galaxies at Redshift 2.38, Immersed in a 100 kpc Scale Ly-alpha Nebula
P. J. Francis, G. M. Williger, N. R. Collins +12
We present Hubble Space Telescope (HST) and ground-based observations of a pair of galaxies at redshift 2.38, which are collectively known as 2142-4420 B1 (Francis et al. 1996). Th…
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…
