Discovery of an X-ray Jet and Extended Jet Structure in the Quasar PKS 1055+201
D. A. Schwartz, H. L. Marshall, J. E. J. Lovell +10
This letter reports rich X-ray jet structures found in the Chandra observation of PKS 1055+201. In addition to an X-ray jet coincident with the radio jet we detect a region of exte…
Observations of Magnetic Fields and Relativistic Beaming in Four Quasar Jets
D. A. Schwartz, H. L. Marshall, J. E. J. Lovell +9
We discuss the physical properties of four quasar jets imaged with the Chandra X-ray Observatory in the course of a survey for X-ray emission from radio jets. These objects have su…
The Knotty Question of the Jet of PKS B1421-490
J. M. Gelbord, H. L. Marshall, D. M. Worrall +9
We report the discovery of unusually strong optical and X-ray emission associated with a knot in the radio jet of PKS B1421-490. The knot is the brightest feature observed beyond t…
A Damped Ly-alpha Absorption-line System in an Apparent Void at Redshift 2.38
L. E. H. Godfrey, P. J. Francis
We study the contents of an apparent void in the distribution of Ly-alpha emitting galaxies at redshift 2.38. We show that this void is not empty, but contains a damped Ly-alpha ab…
