The 300 kpc Long X-ray Jet in PKS 1127-145, z=1.18 Quasar: Constraining X-ray Emission Models
Aneta Siemiginowska, Lukasz Stawarz, C. C. Cheung +4
We present a ~100 ksec Chandra X-ray observation and new VLA radio data of the large scale, 300 kpc long X-ray jet in PKS1127-145, a radio loud quasar at redshift z=1.18. With this…
A method of estimation of the dynamical age of FR II-type radio sources from multifrequency data
J. Machalski, K. T. Chyzy, L. Stawarz +1
We propose a new approach in determining ages of FR II type radio sources. We apply the assumed dynamical model of Kaiser et al. (1997) to a number of FR II type radio galaxies obs…
Confronting X-ray Emission Models with the Highest-Redshift Kiloparsec-scale Jets: the z=3.89 Jet in Quasar 1745+624
C. C. Cheung, L. Stawarz, A. Siemiginowska
A newly identified kiloparsec-scale X-ray jet in the high-redshift z=3.89 quasar 1745+624 is studied with multi-frequency Very Large Array, Hubble Space Telescope, and Chandra X-ra…
Absorption of Nuclear Gamma-rays on the Starlight Radiation in FR I Sources: the Case of Centaurus A
L. Stawarz, F. Aharonian, S. Wagner +1
Several BL Lac objects are confirmed sources of variable and strongly Doppler-boosted TeV emission produced in the nuclear portions of their relativistic jets. It is more than prob…
Radio-Loudness of Active Galactic Nuclei: Observational Facts and Theoretical Implications
M. Sikora, L. Stawarz, J. -P. Lasota
We investigate how the total radio luminosity of AGN-powered radio sources depends on their accretion luminosity and the central black hole mass. Our studies cover about seven orde…
