Neutron star population dynamics

We discuss pulsar space velocities using available proper motion data and other properties of the radio pulsar population. Using a likelihood analysis, we show that all pulsars are consistent with an origination within the galactic disk (other than those in globular clusters or the Magellanic clouds). The same analysis yields estimates for radial velocities of the pulsars and allows indentification of objects whose ages and distances are significantly less than their nominal values. Evidence in favor of asymmetric kicks as the origin for high velocities is summarized. The fraction of objects that escape the Galaxy is estimated. Methods for correcting selection effects that bias the estimated velocity distribution function and the fraction of escaping objects are discussed.
