INTEGRAL detection of the pulsar wind nebula in PSR J1846–0258
INTEGRAL detection of the pulsar wind nebula in PSR J1846–0258
Aims: we communicate the detection of soft (20-200 keV) -rays from the pulsar and pulsar wind nebula of PSR J1846-0258 and aim to identify the component of the system which is responsible for the -ray emission.
Methods: we combine spectral information from the INTEGRAL -ray mission with archival data from the Chandra X-ray Observatory to pinpoint the source of soft -ray emission.
Results: Our analysis shows that the soft -rays detected from PSR J1846-0258 include emission from both the pulsar and the pulsar wind nebula, but the measured spectral shape is dominated by the pulsar wind nebula. We discuss PSR J1846-0258 in the context of rotation-powered pulsars with high magnetic field strengths and review the anomalously high fraction of spin-down luminosity converted into X- and -ray emission in light of a possible overestimate of the distance to this pulsar.

Abstract
Aims: we communicate the detection of soft (20-200 keV) -rays from the pulsar and pulsar wind nebula of PSR J1846-0258 and aim to identify the component of the system which is responsible for the -ray emission.
Methods: we combine spectral information from the INTEGRAL -ray mission with archival data from the Chandra X-ray Observatory to pinpoint the source of soft -ray emission.
Results: Our analysis shows that the soft -rays detected from PSR J1846-0258 include emission from both the pulsar and the pulsar wind nebula, but the measured spectral shape is dominated by the pulsar wind nebula. We discuss PSR J1846-0258 in the context of rotation-powered pulsars with high magnetic field strengths and review the anomalously high fraction of spin-down luminosity converted into X- and -ray emission in light of a possible overestimate of the distance to this pulsar.
