Sky-projected intensity maps at 1 GHz (smoothed with 0.45-arcsec circular beams) from seven simulations viewed along the z-axis. Distinct emission features in each case are marked with arrows, several of which remain key questions for contemporary radio telescopes. Notably, the lack of hotspots in low-magnetization jets–contrasting with their presence in high-magnetization cases–offers crucial insights into the conditions required for hotspot formation in radio galaxies. This contrast is especially significant given that all simulations share identical jet power. While the magnetic field may play a limited role dynamically, it proves critical in shaping the radiative appearance of these sources.
