MENDOZA, S.; HERNANDEZ, X.  and  LEE, W. H.. A possible hydrodynamical equivalence for astrophysical jets. Rev. mex. astron. astrofis [online]. 2005, vol.41, n.2, pp.453-459. ISSN 0185-1101.

The idea of a unified model for quasars and μ-quasars has been considered for a long time, despite the different environments and physical conditions where both classes of objects reside. Here we show the existence of a simple scaling law, relating the maximum size of a jet to the properties of the gas medium into which it expands. This appears to be valid for all types of hydrodynamical jets, and can be thought of as a broad unified model. The expansion velocity of the jet and the physical properties of the surrounding gas combine in such a way that a limit to the maximum extent of jets at different scales can be obtained.
