Abstract

This paper reports our final results related to the study of hot spots (HSs) in a sample of 98 Fanaroff-Riley class II (FR II) radio sources using the VLA at 8.4 GHz. The sample contains 52 radio galaxies (RGs) and 46 quasars (QSRs). We discuss the properties of these HSs, i.e., location (edged or recessed), morphology, and size. The main result is that the number of edged (and recessed) HSs is more for the RGs than for the QSRs. Regarding the compactness of these HSs, QSRs tend to have more compact HSs than RGs. We also found a significant correlation between the hot spot size and the source linear size for the RGs, but not for the QSRs. We discuss the overall properties of the HSs in light of the current models of radio sources.
