Chandra Discovery of a 100 kpc X-ray Jet in PKS 0637--752
D. A. Schwartz, H. L. Marshall, J. E. J. Lovell +18
The quasar PKS 0637-753, the first celestial X-ray target of the Chandra X-ray Observatory, has revealed asymmetric X-ray structure extending from 3 to 12 arcsec west of the quasar…
The gaseous extent of galaxies and the origin of Lyman alpha absorption systems. IV: Lyman alpha absorbers arising in a galaxy group
A. Ortiz-Gil, K. M. Lanzetta, J. K. Webb +2
We present new GHRS observations of Lyman alpha absorption lines associated with a group of galaxies towards the QSO 1545+2101. We have identified eight distinct Lyman alpha absorp…
The Gaseous Extent of Galaxies and The Origin of QSO Absorption Line Systems
H. -W. Chen, K. M. Lanzetta, J. K. Webb +2
We present results of an ongoing program to study the gaseous extent of galaxies and the origin of QSO absorption line systems. For \lya absorption systems, we find that absorption…
Strong Clustering of High-Redshift Lyman-alpha Forest Absorption Systems
A. Fernandez-Soto, K. M. Lanzetta, X. Barcons +3
We use new observations of very weak CIV absorption lines associated with high-redshift Lyman-alpha absorption systems to measure the high-redshift Lyman-alpha line two-point corre…
