Scientific paper

The initial magnetic fields, spin periods, and kick velocities of neutron stars are all tied to the physics of supernova core collapse processes. The velocities and ages of specific NS sub-samples can help constrain the relationships between these parameters. We propose to measure the proper motions of four magnetars - two AXPs and two SGRs. We will exploit the angular resolution of Chandra to match new data to archival observations and thus measure proper motions. The magnitudes and directions of the estimated velocities for the magnetars will constrain the distribution of natal kicks, providing an unprecedented comparison with the radio pulsar population, and confirm or refute associations with supernova remnants and/or stellar clusters.
