Journal ArticleDOI
The radio properties of the broad-absorption-line QSOs
TL;DR: In this paper, a VLA radio detection survey has been conducted for a large sample of broad-absorption-line (BAL) QSOs with no strong radio sources detected.
Journal ArticleDOI
Near-Infrared Camera and Multi-Object Spectrometer Observations of the Hubble Deep Field: Observations, Data Reduction, and Galaxy Photometry
Rodger I. Thompson,Lisa J. Storrie-Lombardi,Ray J. Weymann,Marcia J. Rieke,Glenn Schneider,Elizabeth Stobie,Dyer Lytle +6 more
TL;DR: In this article, the authors present data obtained during the NICMOS Guaranteed Time Observations of a portion of the Hubble Deep Field, in a catalog format similar to the publication of the original WFPC2 Hubble Deep field program (Williams et al.).
Journal ArticleDOI

TL;DR: In this article, the authors combine data from the three preceding papers in order to analyze the multi wave-band variability and spectral energy distribution of the Seyfert 1 galaxy NGC 4151 during the 1993 December monitoring campaign.
Journal ArticleDOI
The Environment of Lyman a Absorbers in the Sightline toward 3C273
Simon L. Morris,Ray J. Weymann,Alan Dressler,P. J. McCarthy,B. A. Smith,R. J. Terrile,R. Gionvanelli,M. Irwin +7 more
TL;DR: In this paper, the authors presented fiber spectroscopy of galaxies within a radius of 1 deg, down to an apparent magnitude of B~19.5 and showed that the absorbers are definitely not distributed at random with respect to the galaxies, but also that the absorbber-galaxy correlation function is not as strong as the galaxy-gating correlation function on large scales.
Journal ArticleDOI
Results of a homogeneous survey of absorption lines in QSOs of small and intermediate emission redshift.
TL;DR: In this article, a spectroscopic survey of an intermediate (1.20z/sub em/) system with vertical-bar Z/Z/Sub em/z/Sub abs/ verticalbar< or approx. = 3000 km s/sup -1/ ) is presented.
