On the Magnetic Field in Kpc-Scale Jets of FR I Radio Galaxies
L. Stawarz, A. Siemiginowska, M. Ostrowski +1
The energy content of large-scale jets in FR I radio galaxies is still an open issue. Here we show that upper limits on the high-energy and very high-energy gamma-ray emission of t…
On the Magnetic Field in Quasar and FR II Large-Scale Jets
L. Stawarz, J. Kataoka
Here we report systematic comparison of the spectral properties of large-scale jets, hotspots and extended lobes in quasars and FR II radio galaxies recently observed with Chandra…
On Multiwavelength Emission and Morphology of Large-Scale Quasar Jets
L. Stawarz, M. Sikora, M. Ostrowski +1
We propose that the knots of the large-scale jets in powerful radio sources represent moving and separate portions of the jet matter, with the excess kinetic power. This can explai…
On relativistic jet/counterjet asymmetry in the presence of radiating jet boundary layer
M. Ostrowski, L. Stawarz
We consider radiation of relativistic electrons accelerated within the jet extended boundary layer. Due to velocity shear across the boundary the observed jet/counterjet brightness…
On particle acceleration in turbulent shear boundary layers of relativistic jets
M. Ostrowski, L. Stawarz
We discuss processes accelerating cosmic ray electrons at boundaries of relativistic jets. The resulting spectrum is expected to posses two characteristic components: a power-law d…
