H.E.S.S. Observations of the Prompt and Afterglow Phases of GRB 060602B
HESS Collaboration, F. Aharonian
We report on the first completely simultaneous observation of a gamma-ray burst (GRB) using an array of Imaging Atmospheric Cherenkov Telescopes which is sensitive to photons in th…
High-energy Particle Acceleration and Production of Ultra-high-energy Cosmic Rays in the Giant Lobes of Centaurus A
M. J. Hardcastle, C. C. Cheung, I. J. Feain +1
The nearby radio galaxy Centaurus A is poorly studied at high frequencies with conventional radio telescopes because of its very large angular size, but is one of a very few extrag…
Chandra Reveals Twin X-ray Jets in the Powerful FR-II Radio Galaxy 3C353
J. Kataoka, L. Stawarz, D. E. Harris +7
We report X-ray imaging of the powerful FR-II radio galaxy 3C353 using the Chandra X-ray Observatory. 3C353's two 4"-wide and 2'-long jets allow us to study in detail the internal…
On the Momentum Diffusion of Radiating Ultrarelativistic Electrons in a Turbulent Magnetic Field
L. Stawarz, V. Petrosian
Here we investigate some aspects of stochastic acceleration of ultrarelativistic electrons by magnetic turbulence. In particular, we discuss the steady-state energy spectra of part…
Radio-loudness of Active Galaxies and the Black Hole Evolution
M. Sikora, L. Stawarz, J. -P. Lasota
Active galactic nuclei (AGNs) form two distinct sequences on the radio-loudness -- Eddington-ratio plane. The `upper' sequence contains radio selected AGNs, the `lower' sequence is…
On the Evolution of and High-Energy Emission from GHz-Peaked-Spectrum Sources
L. Stawarz, L. Ostorero, M. C. Begelman +3
Here we discuss evolution and broad-band emission of compact (< kpc) lobes in young radio sources. We propose a simple dynamical description for these objects, consisting of a rela…
