Abstract : Results from new Chandra-HST-VLA observations of three quasars with redshifts between 0.595 and 0.901 will be presented. These three quasars have Fanaroff-Riley (FR) type II-like radio powers but morphologies that are intermediate between FRIs and FRIIs. Their kiloparsec-scale jets emit copiously in the X-rays but not in the optical, consistent with the IC/CMB mechanism for the production of X-rays. In this and other properties like total radio power, these intermediate quasars resemble regular (i.e., non-intermediate) quasars. However, clearly there quasars either possess intrinsically asymmetric jets or suffer from strong jet bending on scales of tens of kiloparsec just prior to jet termination, to make them intermediate in morphology. We discuss the implications of these findings on ideas of AGN jet formation and propagation.
