Discovery of a Kiloparsec Scale X-ray/Radio Jet in the z=4.72 Quasar GB 1428+4217
C. C. Cheung, L. Stawarz, A. Siemiginowska +4
We report the discovery of a one-sided 3.6" (24 kpc, projected) long jet in the high-redshift, z=4.72, quasar GB 1428+4217 in new Chandra X-ray and VLA radio observations. This is…
A Multi-Wavelength Study of the High Surface Brightness Hotspot in PKS1421-490
L. E. H. Godfrey, G. V. Bicknell, J. E. J. Lovell +9
Long Baseline Array imaging of the z=0.663 broad line radio galaxy PKS1421-490 reveals a 400 pc diameter high surface brightness hotspot at a projected distance of approximately 40…
The Highest Redshift Relativistic Jets
C. C. Cheung, L. Stawarz, A. Siemiginowska +5
We describe our efforts to understand large-scale (10's-100's kpc) relativistic jet systems through observations of the highest-redshift quasars. Results from a VLA survey search f…
Active X-ray Optics for Generation-X, the Next High Resolution X-ray Observatory
Martin Elvis, R. J. Brissenden, G. Fabbiano +8
X-rays provide one of the few bands through which we can study the epoch of reionization, when the first galaxies, black holes and stars were born. To reach the sensitivity require…
