Relativistic Jets in Astrophysics
by
Christian Kaiser
11 September 2001
Relativistic jets are observed in a number of types of astrophysical
objects. In this talk I will review the similarities and differences in
particular between jets in AGNs and those recently found in microquasars our own
Galaxy. I also discuss some of the problems facing us in building theoretical
models for these objects.

central source that has been identified as an Active Galactic Nucleus (AGN)
suspected harboring a supermassive black hole. [Credit, NASA/SAO; Kraft

in our own galaxy. The images are separated in time by only one day with the
advance of the bright 'knots' along the jets is clearly visible.
