Investigating the emission mechanism in the spatially-resolved jet of two z 3 radio-loud quasars

Jaya Maithil, Daniel A. Schwartz, Aneta Siemiginowska +9

This study focuses on high-redshift, z > 3, quasars where resolved X-ray jets remain underexplored in comparison to nearby sources. Building upon previous work, we identify and con…

A Multi-band Study of the remarkable Jet in Quasar 4C+19.44

Daniel Harris, Nicholas Lee, Dan Schwartz +14

We present arc-second-resolution data in the radio, IR, optical and X-ray for 4C+19.44 (=PKS 1354+195), the longest and straightest quasar jet with deep X-ray observations. We repo…

A survey of X-ray emission from 100 kpc radio jets

Daniel A Schwartz, Herman L Marshall, Diana M Worrall +8

We have completed a Chandra snapshot survey of 54 radio jets that are extended on arcsec scales. These are associated with flat spectrum radio quasars spanning a redshift range z=0…

An X-ray Imaging Survey of Quasar Jets -- Testing the Inverse Compton Model

H. L. Marshall, J. M. Gelbord, D. A. Schwartz +7

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

A Flare in the Jet of Pictor A

H. L. Marshall, M. J. Hardcastle, M. Birkinshaw +11

A Chandra X-ray imaging observation of the jet in Pictor A showed a feature that appears to be a flare that faded between 2000 and 2002. The feature was not detected in a follow-up…

First Results from a Multi-wavelength Survey of Quasar Jets

J. M. Gelbord, H. L. Marshall, D. A. Schwartz +7

We present results based on the first 20 Chandra images obtained in a survey of jets in radio selected flat-spectrum quasars (FSRQs), along with new sub-arcsecond radio maps and op…
