Scientific paper

An ACIS exposure of PSR J0538+2817 in S147 can powerfully test the origin of pulsar birth kicks. This is because the pulsar has the longest initial spin period of any radio pulsar/SNR presently known, yet the faint wind nebula that we discovered in a short AO3 exposure shows symmetry, marking the neutron star spin axis, well aligned with the proper motion vector. Our predicted large birth period and proper motion now have a pulsar timing confirmation. We have a VLBA campaign underway that will provide a high precision velocity vector (and distance). A sensitive ACIS exposure can complete the test, confirming the modeled PWN structure and measuring the symmetry axis with comparable precision. The resulting spin-kick angle measurement can rule out many popular models for the birth kick.
