The VIIth catalogue of galactic PopulationI Wolf–Rayet stars provides improved coordinates,
spectral types and bv photometry of known WR stars and adds 71 new WR stars to the …

In the first part of this review we discuss the basic observational features at the end of the
cosmic ray (CR) energy spectrum. We also present there the main characteristics of each of …

Gamma ray astronomy, the branch of high energy astrophysics that studies the sky in
energetic γ-ray photons, is destined to play a crucial role in the exploration of nonthermal …

The creation of a photon–atom bound state was first envisaged for the case of an atom in a
long-lived excited state inside a high-quality microwave cavity,. In practice, however, light …

The jets of microquasars with high-mass stellar companions are exposed to the dense
matter field of the stellar wind. We present estimates of the gamma-ray emission expected …

The dramatic increase in the number of known gamma-ray pulsars since the launch of the
Fermi Gamma-ray Space Telescope (formerly GLAST) offers the first opportunity to study a …

Deep observation (~ 113 hrs) of the Cygnus region at TeV energies using the HEGRA
stereoscopic system of air Čerenkov telescopes has serendipitously revealed a signal …

Colliding winds of massive star binary systems are considered as potential sites of
nonthermal high-energy photon production. Motivated by the detection of synchrotron radio …

We use hydrodynamical models of the wind-collision region in the archetype colliding-wind
system WR 140 to determine the spatial and spectral distributions of the radio, X-ray, and γ …
