These court cases are the results of a three-day assembly held in Oogliani (Italy), on October 2-4 2003, whose identify was once "VIrtual Astrophysical Jets 2003". Our objective in convening this assembly used to be to assemble the various scientists one of the such a lot energetic within the box of numerical simulations and modelling of astrophysi cal jets. For conserving the individuals with reference to the "real world", we additionally invited a couple of observers to provide up to date reports outlining the cutting-edge of jet observations. The imperative goal of the assembly was once hence to give and significantly speak about the cutting-edge numerical simulations, analytical versions and laboratory ex periments for reproducing the most elements of astrophysical jets and compar ing them with observations. The dialogue has been eager about the next themes: • Observations and intepretions of jets from younger stars and AGNs, comparisons of versions with observations; • MHO accelerations of jets: regular self-similar types, MHO numerical simula tions of time-dependent accelerations mechanisms; • Jet balance and interplay with the ambient: formation of knots in YSO jets, jet survival to instabilities, deceleration of relativistic jets in FRI resources, simulations of jets-IGM interactions, jets propagation and galaxy formation; • Numerical codes and their validation: relativistic MHO codes, comparisons between various numerical schemes, jets within the laboratory and code validation. those themes were mentioned intensively through the assembly, and the out come of those discussions is gifted during this quantity. The contributions were divided in 5 sections.
