Pulsar Wind Nebulae Created by Fast-Moving Pulsars
Abstract
We review multiwavelength properties of pulsar wind nebulae (PWNe) created by supersonically moving pulsars and the effects of pulsar motion on the PWN morphologies and the ambient medium. Supersonic pulsar wind nebulae (SPWNe) are characterized by bow-shaped shocks around the pulsar and/or cometary tails filled with the shocked pulsar wind. In the past several years significant advances in SPWN studies have been made in deep observations with the Chandra and XMM-Newton X-ray Observatories as well as the Hubble Space Telescope. In particular, these observations have revealed very diverse SPWN morphologies in the pulsar vicinity, different spectral behaviors of long pulsar tails, the presence of puzzling outflows misaligned with the pulsar velocity, and far-UV bow shocks. Here we review the current observational status focusing on recent developments and their implications.
