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…
Low angular momentum accretion flow model of Sgr A* activity
B. Czerny, M. Moscibrodzka, D. Proga +2
Sgr A* is a source of strongly variable emission in several energy bands. It is generally agreed that this emission comes from the material surrounding the black hole which is eith…
The Case of the 300 kpc Long X-ray Jet in PKS 1127-145 at z=1.18
Aneta Siemiginowska, D. E. Harris, Thomas L. Aldcroft +4
The complex X-ray morphology of the 300 kpc long X-ray jet in PKS1127-145 (z=1.18 quasar) is clearly discerned in a ~100 ksec Chandra observation. The jet X-ray surface brightness…
