The Absorption Spectrum of High-Density Stellar Ejecta in the Line-of-Sight to Eta Carinae
T. R. Gull, G. Vieira, F. Bruhweiler +3
Using the high dispersion NUV mode of the Space Telescope Imaging Spectrograph (STIS) aboard the Hubble Space Telescope (HST) to observe Eta Carinae, we have resolved and identifie…
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…
The central region of the Fornax cluster -- II. Spectroscopy and radial velocities of member and background galaxies
M. Hilker, L. Infante, G. Vieria +2
Radial velocities of 94 galaxies brighter than about V_tot = 20 mag in the direction of the central Fornax cluster have been measured. Except for 8 Fornax members, all galaxies lie…
