PSR J1119-6127 is a young, yet slow, rotation-powered radio and X-ray pulsar associated with SNR G292.2-0.5. Its inferred high surface magnetic field of B = 4.1×1013 Gauss is interestingly close to the critical QED value above which pulsars are believed to enter the magnetar regime. In 2003, we have detected the X-ray counterpart of the radio pulsar with Chandra and provided the first evidence for a compact and faint pulsar wind nebula (PWN, [3]). We here present new Chandra observations of the pulsar, thus providing a deep (~140 ksec total) exposure. The observations allowed 1) a confirmation of the PWN detection, 2) a high-resolution imaging study revealing the structure of the PWN, and 3) for the 1st time a spectroscopic study of the pulsar independently from its surrounding nebula. We discuss the implications of our study to our understanding of this unique system and more generally to the manifestation of high magnetic field radio pulsars in X-rays, in comparison with the more `classical' rotation-powered pulsars and magnetars.
