Physical properties of the jet in 0836+710 revealed by its transversal structure(Corrigendum)

subject

description

Perucho & Lobanov (2007) (PL07, from now on) presented results demonstrating that the jet in 0836+710 has a significant velocity shear layer. These authors used a set of jet parameters found by Lobanov et al. (1998) (including Lorentz factor γ = 11, Mach number Mj = 6, and jet/ambient medium density ratio ρj/ρa = 0.04). They studied different characteristic wavelengths that may develop in a jet with both a thin ( 10% of the jet radius) and a thick shear-ayer ( 60% of the jet radius). The result showed that the observed wavelengths in the jet structure could be more easily explained in terms of a transversally stratified jet. A mistake was, however made in PL07: the equation used to convert the instrinsic into an observed wavelength was incorrect, because it included cosmological effects. The correct equation should have been
