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 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…
Discovery of a Jet-Like Structure at the High Redshift QSO CXOMP J084128.3+131107
D. A. Schwartz, J. Silverman, M. Birkinshaw +7
The Chandra Multiwavelength Project (ChaMP) has discovered a jet-like structure associated with a newly recognized QSO at redshift z=1.866. The system was 9.4 arcmin off-axis durin…
An X-ray View of Radio Sources
Daniel A. Schwartz
We review recent examples where the synergy between radio and X-ray observations has led to substantial progress in understanding astronomical systems. The sub-arcsecond imaging ca…
