Propagation of gamma-rays in massive binary Cen X-3: Interaction of cascade gamma-rays with the massive star

W. Bednarek

We consider the propagation of very high energy (VHE) gamma-rays in the radiation field of the massive star of binary system Cen X-3. VHE gamma-rays or electrons, injected by the c…

Gamma-rays from Collisions of Compact Objects with AGN Jets?

W. Bednarek

We consider different scenarios of collisions of compact objects (clouds, massive stars, supernova shock waves, or young pulsars) with jets in active galactic nuclei. The purpose i…

Cascades initiated by EHE photons in the magnetic field of the Earth and the Sun

W. Bednarek

The content of extremely high energy (EHE) photons in the highest energy cosmic rays can be investigated by analyzing showers arriving from directions where the perpendicular compo…

SN 1998bw--GRB 980425: A supernova explosion with a close massive companion?

R. J. Protheroe, W. Bednarek

Some gamma ray bursts may be produced by supernovae exploding in close massive binary systems (type Ib/c supernovae) as suggested by the recent observation of SN 1998bw/GRB 980425.…

On the application of the mirror model for gamma-ray flare in 3C 27

W. Bednarek

Multiwavelength observations of high energy flare in 1996 from 3C 279 seems to favour the so called mirror model between different inverse Compton scattering models proposed as a p…

Production of gamma-rays in blazars

W. Bednarek

Some aspects of theory of gamma-ray production in blazar type active galaxies are discussed in the context of recent observations.
