Abstract
We examined the influence of environmental/intrinsic factors on the apparent asymmetries observed in the arm-lengths and luminosities of the lobes of double extragalactic radio sources. We showed that the observed arm-length ratio \(( Q' ) \) is modified by environmental/intrinsic factors, which increases with increasing anisotropy in the environment. Also the modification seems higher for quasars than for FR-II radio galaxies. Using the power-law model of flux evolution in extragalactic radio sources, our analysis showed similar trend in the modification of observed lobe luminosity ratio by environmental/intrinsic factors. Our result also showed that the environmental influence on the observed asymmetries increases as radio source linear size decreases and seems higher for radio sources with observed lobe luminosity ratio (\(R<1\)) than for radio sources with \(R\geq 1\).
