Abstract

We used both analytical and statistical methods of analyses to find out if there is possible connection between jet opening solid angle and linear size evolution of some powerful extragalactic radio sources in our sample. Based on simple linear regression analyses of D-Ω data (where D is observed linear size and Ω is estimated jet opening solid angle), we found with a marginal correlation, that effects contributed by the opening angle may be overshadowed by other factors. A plausible interpretation of the result is that there is presence of appreciable ambient gases around these sources.
