Revisiting the Pulsar Injection Problem

We propose XMMNewton observations of three Galactic supernova remnants withpositionally coincident radio pulsars in order to confirm or refute theplausible connection between the supposedly old (but possibly very young)pulsars and the supernova remnants. Based on this we could (i) constrain theGalactic population of neutron stars born spinning slowly, (ii) determine anyconnection between the new class of socalled antimagnetars and normal radiopulsars, (iii) extend the grossly incomplete Xray catalog of Galactic supernovaremnants, and (iv) if the pulsars are not related to the remnants, look for acentral compact object and/or a pulsar wind nebula. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
