Magnetosphere-PWN-Velocity Connection: Resolving the X-ray PWN in CTA 1
Abstract
CXO observations often reveal pulsar wind nebulae (PWNe) with jets and/or tori allowing one to measure the angle between the pulsar's spin axis and the line-of-sight. If a pulsar's GeV lightcurve is available, then by fitting the magnetospheric emission model one can also determine the magnetic inclination angle for a known viewing angle. If the pulsar is nearby and moving fast enough, one can measure the transverse velocity. However, if the jets are resolved, then the estimation of the kick angle between the pulsar velocity and spin axis becomes possible by modeling the jet bending. The PWN in the nearby CTA 1 SNR is one of such rare cases. Deep CXO observations of such PWNe shed light on the connection between the pulsar magnetosphere geometry, PWN morphologies, and supernova kicks.
