These Lecture Notes focus on the physics of relativistic jet
sources in the universe, from galactic microquasars to active
galactic nuclei (AGN). The early 21st century is an epoch in which
a large number of high-energy astronomical missions are underway
(RossiXTE, Chandra, XMM-Newton, INTEGRAL, Swift, Suzaku). The
wealth of X-ray and gamma-ray data, coupled with ground-based
observations in the optical/IR/radio bands, provides an increasing
amount of... more...
