The Extended Morphology of Ultraluminous Radio Cores
Abstract
This article investigates the extended radio morphology of a large sample of extremely powerful quasar radio cores. It is found that the extended emission is on the order of weak FRII luminosity for the most part even though the sources are at high redshift, the average redshift of the sample is 1.84. Furthermore, the sources in this catalog were observed with a dynamic range between 500 and 10000 with the VLA, yet 30% of them are naked cores. It is argued through map morphology and polarimetry data that the sources with the strongest extended emission are dominated by Doppler enhanced beamed kiloparsec scale jets. If viewed near the sky plane, even these sources, would have weak FRII luminosities, at best.
