A Chandra proper motion for PSR J1809-2332.
VAN ETTEN A., ROMANI R.W. and NG C.-Y.
Abstract (from CDS):
We report on a new Chandra exposure of PSR J1809-2332, the recently discovered pulsar powering the bright EGRET source 3EG J1809-2328. By registration of field X-ray sources in an archival exposure, we measure a significant proper motion for the pulsar point source over an ~11 yr baseline. The shift of 0.30±0".06 (at P.A. = 153.3±18.4) supports an association with proposed supernova remnant (SNR) parent G7.5-1.7. Spectral analysis of diffuse emission in the region also supports the interpretation as a hard wind nebula trail pointing back toward the SNR.
