The Fundamental Planes of Black Hole Activity for Radio-Loud and Radio-Quiet Quasars
Luis Gabriel C. Bariuan, Bradford Snios, Małgosia Sobolewska +2
We examine the fundamental plane of black hole activity for correlations with redshift and radio loudness in both radio-loud and radio-quiet quasar populations. Sources are compile…
Discovery of Candidate X-ray Jets in High-Redshift Quasars
Bradford Snios, Daniel A. Schwartz, Aneta Siemiginowska +8
We present Chandra X-ray observations of 14 radio-loud quasars at redshifts , selected from a well-defined sample. All quasars are detected in the 0.5-7.0 keV energy ban…
X-ray Properties of Young Radio Quasars at z > 4.5
Bradford Snios, Aneta Siemiginowska, Małgosia Sobolewska +6
We present a comprehensive analysis of Chandra X-ray observations of 15 young radio quasars at redshifts . All sources are detected in the keV energy band.…
The High-energy emission of jetted AGN
Daniel A. Schwartz
Quasars with flat radio spectra and one-sided, arc-second scale, ~100 mJy GHz radio jets are found to have similar scale X-ray jets in about 60% of such objects, even in short 5 to…
Relativistic X-ray jets at high redshift
Daniel A Schwartz, Aneta Siemiginowska, Diana M Worrall +6
Powerful radio sources and quasars emit relativistic jets of plasma and magnetic fields that travel hundreds of kilo-parsecs, ultimately depositing energy into the intra- or inter-…
An X-ray Imaging Survey of Quasar Jets -- The Complete Survey
H. L. Marshall, J. M. Gelbord, D. M. Worrall +8
We present Chandra X-ray imaging of a flux-limited sample of flat spectrum radio-emitting quasars with jet-like structure. X-rays are detected from 59% of 56 jets. No counterjets w…
