Analysis of JET component parameters of AGN -brightness, speed, size, distance and acceleration

Abstract

We statistically analysed the jet component parameters of superluminal sources which comprises of radio galaxy (G), radio quasar (Q) and BL Lac (B) objects. Subsamples were formed based on brightness, speed, size, distance D from the assumed stationary core, jet components with positive and negative perpendicular and parallel acceleration. Results show that there is a strong positive correlation between the jet component size and distance away from the core, which supports the self-similarity model of AGN evolution and that jet component accelerations are independent of any size, distance from the core, radio power and speed of the jet component. Moreover, jet components with negative/positive acceleration have similar range in values in the observed parameters.
