Spectral Index Asymmetries in Low-Z Radio Galaxies
In recent years a number of correlations have been observed between the large-scale properties of FRII radio galaxies and quasars. Some correlations find their simplest explanations in terms of environmental effects, others in terms of beaming/orientation effects. The problem, however, is that there is an implied correlation between these different types of effects. This is a report on work underway to investigate this directly and exclude the confusion introduced by use of different samples.
