The book "Virtual Astrophysical Jets" documents the results of a three-day meeting that took place from October 2 to 4, 2003, in Oogliani, Italy. The aim of this conference was to bring together leading scientists in the field of numerical simulations and modeling of astrophysical jets. In addition to simulation experts, observers were also invited to present current findings on the state of jet observations. The main objectives of the meeting included a critical discussion on the current state of numerical simulations, analytical models, and laboratory experiments aimed at reproducing the essential aspects of astrophysical jets and their comparison with observations. The topics covered ranged from the observation and interpretation of jets from young stars and active galactic nuclei to numerical codes and their validation. This comprehensive collection of contributions provides valuable insights into the advances and challenges in the research of astrophysical jets.
