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 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…
Cosmic ray propagation and acceleration
M. Ostrowski
This report covers the studies of energetic particle propagation and acceleration presented during the 27th ICRC in sessions OG 1.3 and 1.4, plus a few selected papers from neighbo…
Numerical Simulations of Relativistic Shock Acceleration
M. Ostrowski
We review the present status of the cosmic ray acceleration theory in mildly relativistic shock waves. Due to the involved substantial particle anisotropies analytical methods can…
