The Low-Redshift Lyman Alpha Forest toward 3C 273
G. M. Williger, R. F. Carswell, R. J. Weymann +6
We present an analysis of the Ly-a forest toward 3C 273 from the Space Telescope Imaging Spectrograph at ~7 km/s resolution, along with re-processed data from the Far Ultraviolet S…
Discovery of a Dwarf Post-Starburst Galaxy Near a High Column Density Ly-alpha Absorber
J. T. Stocke, B. A. Keeney, K. M. McLin +3
We report the discovery of a dwarf (M_B = -13.9) post-starburst galaxy coincident in recession velocity (within uncertainties) with the highest column density absorber (N_HI = 10^1…
STIS Spectroscopy of PKS 0405-123
G. Williger, S. Heap, R. Weymann +2
We present results for QSO PKS 0405-123 (z=0.574, V=14.9), as part of a STIS Investigation Definition Team (IDT) key project to study weak Ly-alpha forest systems at low z. We dete…
High Redshift Candidates and the Nature of Small Galaxies in the Hubble Deep Field
Lisa J. Storrie-Lombardi, Ray J. Weymann, Rodger I. Thompson
We present results on two related topics: 1. A discussion of high redshift candidates (z>4.5), and 2. A study of very small galaxies at intermediate redshifts, both sets being dete…
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…
HST/STIS Spectroscopy of 3C 273
S. R. Heap, G. M. Williger, R. Dave +3
We present preliminary results on the low-redshift Lyman alpha forest as based on STIS spectra of 3C 273. A total of 121 intergalactic Lyman alpha-absorbing systems were detected,…
