Scales of the radio sources, d, at different times (100 Myr, 300 Myr, and 500 Myr) varying with the jet powers. We determined the scales of the radio sources by doubling the distance from the heads of the one-sided radio lobes to the center of galaxy. The stars are color-coded to represent distinct fractions of energy components and the magnetic structure parameter, α_p. The arrow indicates that the source is larger than the simulated region.
