Abstract: This PhD thesis aims at understanding the particle escape and subsequent emission processes taking place in Bow-shock Pulsar Wind Nebulae (BSPWNe), trying to connect a) the observational findings of large X-ray jet-like structures resolved in some of these systems; b) the phenomenology associated to the recently discovered gamma-ray TeV halos, and c) the prediction of similar extended structures in the radio band. To this end, three BSPWN with prominent extended emission features detected in X-rays showing evidence of such particle escape mechanisms have been studied and presented in this thesis.
