Detailed Structure of the X-ray Jet in 4C 19.44 (=PKS1354+195)
D. A. Schwartz, D. E. Harris, H. Landt +9
We investigate the variations of the magnetic field, Doppler factor, and relativistic particle density along the jet of a quasar at z=0.72. We chose 4C 19.44 for this study because…
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…
X-Ray Evidence for Multiple Absorbing Structures in Seyfert Nuclei
Jonathan M. Gelbord, Kimberly A. Weaver, Tahir Yaqoob
We have discovered a correlation between the X-ray absorbing column densities within Seyfert galaxies and the relative alignment between the central engines and their host galactic…
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…
Continuing a Chandra Survey of Quasar Radio Jets
J. M. Gelbord, H. L. Marshall, D. A. Schwartz +7
We are conducting an X-ray survey of flat spectrum radio quasars (FSRQs) with extended radio structures. We summarize our results from the first stage of our survey, then we presen…
