Abstract

We present the results of a deep ROSAT HRI observation of the supernova remnant Kes 32 and the possibly associated pulsar PSR B1610-50. The supernova remnant shows strongly energy dependent complex structures in a comparison with the ASCA GIS and ROSAT PSPC data with low foreground absorption ([FORMULA] cm-2). The pulsar is not seen in the HRI image indicating a high absorbing column density ([FORMULA] cm-2) along the line of sight, making the physical connection between Kes 32 and PSR B1610-50 unlikely. The elongated structure south of the pulsar, interpreted as a pulsar jet, might be an unrelated foreground emission.

Key words: ISM: supernova remnants – ISM: jets and outflows – stars: pulsars: individual: PSR B1610-50 – X-rays: ISM
