Query: Plasma Phenomenology in Astrophysical Systems: Radio-Sources and Jets   We review the plasma phenomenology in the astrophysical sources which show
appreciable radio emissions, namely Radio-Jets from Pulsars, Microquasars,
Quasars and Radio-Active Galaxies. A description of their basic features is
presented, then we discuss in some details the links between their morphology
and the mechanisms that lead to the different radio-emissions, investigating
especially the role played by the plasma configurations surrounding compact
objects (Neutron Stars, Black Holes). For the sake of completeness, we briefly
mention observational techniques and detectors, whose structure set them apart
from other astrophysical instruments. The fundamental ideas concerning Angular
Momentum Transport across plasma accretion disks (together with the
disk-source-jet coupling problem) are discussed, by stressing their successes
and their shortcomings. An alternative scenario is then inferred, based on a
parallelism between astrophysical and laboratory plasma configurations, where
small-scale structures can be found. We will focus our attention on the
morphology of the radio-jets, on their coupling with the accretion disks and on
the possible triggering phenomena, viewed as profiles of plasma instabilities.
