    • For example, an explanation of the apparent absence of a counterjet in Cen A via relativistic beaming suggests that the angle of the visible jet axis with respect to the line of sight is at most 36° [20], which could lead to a doubling of the hot spot radius. It should be remarked that for a distance of 3.4 Mpc, the extent of the entire source has a reasonable size even with this small angle.

    • Simulations of the magnetic field in shock environments reveal a complex Mach disk and extended oblique shock structure. Therefore, it is necessary to consider the entire shock environment for a complete picture of particle acceleration, confinement, and transport. Semi-realistic simulations of such struc
