Abstract
New high-dynamic-range radio observations, made with the VLA in the A array at 2 cm with a resolution of 0.1 arcsec, are reported. The new maps show a complex pattern of filamentary and other fine-scale structures in the jet. A new physical interpretation of the jet, suggested by these observations, is presented. It is concluded that the overall morphology of M87 is more consistent with a boundary layer phenomena rather than with a structure dominated by shocks or other centrally driven flow phenomena. This morphology appears to be most consistent with a picture in which electrodynamic phenomena play an important role in the physics. 27 refs.
