The Hubble Deep Field South Flanking Fields
Ray A. Lucas, Stefi A. Baum, Thomas M. Brown +22
As part of the Hubble Deep Field South program, a set of shorter 2-orbit observations were obtained of the area adjacent to the deep fields. The WFPC2 flanking fields cover a conti…
The Ionized Gas and Nuclear Environment in NGC 3783 II. Averaged HST/STIS and FUSE Spectra
Jack R. Gabel, D. Michael Crenshaw, Steven B. Kraemer +14
We present observations of the intrinsic absorption in the Seyfert 1 galaxy NGC 3783 obtained with the STIS/HST and FUSE. We have coadded multiple STIS and FUSE observations to obt…
Balmer and He I absorption in the nuclear spectrum of NGC 4151
J. B. Hutchings, D. M. Crenshaw, S. B. Kraemer +4
Spectra taken with the Space Telescope Imaging Spectrograph (STIS) allow accurate location and extraction of the nuclear spectrum of NGC 4151, with minimal contamination by extende…
Associated Absorption Lines in the Radio-Loud Quasar 3C 351: Far-Ultraviolet Echelle Spectroscopy from the Hubble Space Telescope
Q. Yuan, R. F. Green, M. Brotherton +3
As one of the most luminous radio-loud quasars showing intrinsic ultraviolet (UV) and X-ray absorption, 3C 351 provides a laboratory for studying the kinematics and physical condit…
The Heavy Element Enrichment of Lyman alpha Clouds in the Virgo Supercluster
T. M. Tripp, E. B. Jenkins, G. M. Williger +11
Using high S/N STIS echelle spectra (FWHM=7 km/s) of 3C 273, we constrain the metallicities of two Lya clouds in the vicinity of the Virgo cluster. We detect C II, Si II, and Si II…
The Ionized Gas and Nuclear Environment in NGC 3783. I. Time-Averaged 900 ks Chandra Grating Spectroscopy
S. Kaspi, W. N. Brandt, I. M. George +15
We present results from a 900 ks exposure of NGC 3783 with the High-Energy Transmission Grating Spectrometer on board the Chandra X-ray Observatory. The resulting X-ray spectrum ha…
