PSR J1119-6127 is a newly discovered 407 ms radio pulsar (Camilo et al. 2000) associated with the 15'x20' diameter supernova remnant (SNR) G292.2-0.5 (Crawford et al. and Pivovaroff et al. 2001). We present a preliminary study of this pulsar/SNR association using a 50 ks Chandra AO-3 observation. Our imaging and spectroscopic study with the S3 chip reveals a faint X-ray source at the radio coordinates of the pulsar. Its spectrum is well described by a power law model with a photon index of 2.2 and a 0.5-10 keV luminosity of ~4E32 erg/s (at a distance of 5 kpc). We therefore identify this source as the X-ray counterpart of the radio pulsar J1119-6127. Thanks to the excellent spatial resolution and sensitivity offered by Chandra, our study also reveals a very faint extended component of ~3"x5" in size, and which we believe to be associated with the pulsar's outflow. Diffuse emission from the interior of the remnant is also detected throughout the field. This emission is found to be well characterized by a two-component model revealing both thermal and nonthermal contributions to the SNR's spectrum. We acknowledge support by NSERC.
