On magnetic fields in broad-line blazars
R. Moderski, M. Sikora
High energy spectra of broad-line blazars can be reproduced by both synchrotron-self-Compton (SSC) models and external-Compton (EC) models. However, as is known from numerical mode…
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…
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…
Dynamics and High Energy Emission of the Flaring HST-1 Knot in the M 87 Jet
L. Stawarz, F. Aharonian, J. Kataoka +3
Stimulated by recent observations of a radio-to-X-ray synchrotron flare from HST-1, the innermost knot of the M 87 jet, as well as by a detection of a very high energy gamma-ray em…
