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…

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…

Chandra measurement of the X-ray spectrum of a quasar at z=5.99

Daniel A. Schwartz, Shanil N. Virani

We report the first measurement of the X-ray spectrum of the z = 5.99 quasar SDSSp J130608.26+035626.3 from a 120 ks observation by the Chandra ACIS-S instrument. Between 0.5 and 7…

A Chandra Survey of Quasar Jets: First Results

H. L. Marshall, D. A. Schwartz, J. E. J. Lovell +6

We present results from Chandra X-ray imaging and spectroscopy of a flux-limited sample of flat spectrum radio-emitting quasars with jet-like extended structure. Twelve of twenty q…
