A ROSAT HRI OBSERVATION OF THE SUPERNOVA REMNANT G109.1-1.0

We present results of a search using ROSAT HRI data for X-ray spatial substructures in the galactic supernova remnant G109.1 - 1.0 which mig ht indicate a connection between the remnant's bright X-ray blob and i ts X-ray pulsar, 1E2259 + 586. A 0.1-2.4 keV HRI image, created by com bining separate 28- and 22-ks pointings, reveals the presence of a few small-scale X-ray features, including a NE-SW emission ridge in the r emnant's X-ray blob. Two diffuse knots in the X-ray blob, previously s uggested as being aligned with the X-ray pulsar, appear to be statisti cal fluctuations in the Einstein HRI data. We find no morphological ev idence in the X-ray spatial substructures of G109.1 - 1.0 to support a pulsar jet origin for the X-ray blob as proposed by Gregory & Fahlman .
