Microquasars and Gamma-ray Sources
(Science Press, 2005-12)
Microquasars are X-ray binary systems with non-thermal radio emission originated in jet-like features. They are attractive sites for gamma-ray production, since relativistic particles in the jet should traverse locally ...
An upper limit on the cosmic-ray luminosity of individual sources from gamma-ray observations
(Institute of Physics - IOPBristol, 2013-12)
Different types of extragalactic objects are known to produce TeV gamma-rays. Some of these objects are the most probable candidates to accelerate cosmic rays up to '10 POT.20' eV. It is very well known that gamma-rays can ...

Precessing microblazars and unidentified gamma-ray sources
(EDP Sciences, 2002-12)
The recent discovery by Paredes et al. (\cite{Paredes}) of a persistent microquasar that is positionally coincident with an unidentified gamma-ray source has open the possibility that other sources in the Third EGRET Catalog ...
