Description
Young neutron stars power bright multi-wavelength emission and drive energetic pulsar wind nebulae (PWNe). Accurate interpretation of these signals depends on the magnetic inclination ($\alpha$) and viewing angle ($\zeta$); however, independent observables often yield conflicting geometric constraints. To investigate these discrepancies, we analysed a sample of eight high-spin-down pulsars ($\dot{E} \gtrsim 10^{34}$ erg/s), categorised by characteristic age into Crab-like ($\sim$1 kyr) and Vela-like ($\sim$10 kyr) populations. For each source, we applied three independent geometric tracers: radio polarimetry (Rotating Vector Model), $\gamma$-ray light-curve modelling (TPC/OG/CS models), and X-ray imaging of PWN tori. Our comparison reveals that while some pulsars show multi-wavelength consistency, others exhibit significant geometric offsets. Our results suggest that standard emission models may require refinements, particularly regarding emission altitudes or magnetospheric structure, to reconcile the geometry across the electromagnetic spectrum.
