The Low-Redshift Lyman Alpha Forest toward PKS 0405-123
G. M. Williger, S. R. Heap, R. J. Weymann +5
We present STIS 7km/s resolution data of the Ly-a forest toward PKS0405-123 (z=0.574). We make two samples. The strong sample (60 systems) has column density logNHI>13.3 over 0.002…
The Local Lyman-Alpha Forest: Absorbers in Galaxy Voids
Kevin M. McLin, John T. Stocke, R. J. Weymann +2
We have conducted pointed redshift surveys for galaxies in the direction of bright AGN whose HST far-UV spectra contain nearby (cz <~ 30,000 kms), low column density (12.5 <= log N…
High-Resolution Keck Spectra of the Associated Absorption Lines in 3C 191
Frederick W. Hamann, T. A. Barlow, F. C. Chaffee +2
Associated absorption lines (AALs) are valuable probes of the gaseous environments near quasars. Here we discuss high-resolution (6.7 km/s) spectra of the AALs in the radio-loud qu…
NICMOS Imaging of a Damped Lyman-alpha Absorber at z=1.89 toward LBQS 1210+1731 : Constraints on Size and Star Formation Rate
Varsha P. Kulkarni, John M. Hill, Glenn Schneider +5
We report results of a high-resolution imaging search (in rest frame H- and optical continuum) for the galaxy associated with the damped Lyman- (DLA) absorber at to…
Multiwavelength observations of short time-scale variability in NGC 4151. I. Ultraviolet observations
D. M. Crenshaw et al
We present the results of an intensive ultraviolet monitoring campaign on the Seyfert 1 galaxy NGC 4151, as part of an effort to study its short time-scale variability over a broad…
