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…

X-ray Evidence for Multiple Absorbing Structures in Seyfert Galaxies

Jonathan Gelbord, K. A. Weaver, T. Yaqoob

We have used X-ray spectra to measure attenuating columns in a large sample of Seyfert galaxies. Over 30 of these sources have resolved radio jets, allowing the relative orientatio…

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…
