High resolution X-ray study of the Galactic Supernova Remnant G292.2-0.5 associated with the high magnetic field pulsar PSR J1119-6127
Abstract
We present results from Chandra and XMM-Newton observations of the Galactic supernova remnant (SNR) G292.2-0.5 containing the high magnetic field radio pulsar PSR J1119-6127. PSR J1119-6127 is a young (1700 yr-old) rotation-powered pulsar, with a relatively large period (408 ms) and magnetic field (4.1x1013 G) compared to Crab-like pulsars. Previous Chandra studies of this composite system allowed the detection of the pulsar, the discovery of an associated compact pulsar wind nebula (PWN), and a spatially resolved spectroscopic study of the western side of the SNR. An XMM-Newton observation of this system allowed for the detection of X-ray pulsations with unusual characteristics from the pulsar. Here, we present a high resolution study of the SNR G292.2-0.5 using all available Chandra and XMM-Newton observations, in order to characterize the spatial and spectral properties of the diffuse emission from the entire SNR and to better constrain the deposition of the pulsar's wind energy into its surroundings. The present study is also targeted to address the nature of the progenitor star of SNR G292.2-0.5, in comparison with the SNR Kes 75 suggested to result from the explosion of a Wolf-Rayet star and associated with the young (≤ 884 yr-old) high magnetic field X-ray pulsar PSR J1846-0258, recently discovered to behave like a magnetar, and having spin properties very similar to PSR J1119-6127.
