INTEGRAL detection of the pulsar wind nebula in PSR J1846–0258

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.
