Stars and Cosmic Rays,ouds: they excite giant HII regions, inside which they create large wind cavities. The possibility of particle acceleration by wind shocks then allows to introduce the concept of thick cosmic-ray sources. The high-energy particles generated by such sources are very different from those associated wi

Radio Astronomy and Cosmic Rays,possibly, or even probably, originates in supernovae and/or supernova remnants. Therefore in consideration of this electronic component, we review the general history and observed properties of supernovae with concentration on the more recent results or radio supernovae, the observed properties of s

Particle Acceleration in Galactic Supernova Remnants,ion. Young, bright shell remnants generally have spectral indices α larger than the 0.5 expected from basic shock acceleration theory. Fainter, older shell remnants have a wide range of α. Evidence on whether or not particle acceleration is continuing in SNRs is also discussed.

Conditions for Acceleration of Super-High Energy Cosmic Rays in Active Galactic Nuclei,The current system might resemble an electrical circuit with a voltage source (black hole and accretion disc) coupled to a load (cosmic-ray beam) and a low impedance element (ambient conducting medium). Beam particles can be accelerated to 10. provided that the beam channel medium behaves like an in
