“…Carter et al (1997) found an optical expansion rate of 1100 km s −1 . Radio observations of RCW 103 at 2372 and 1362 MHz reveal a diffuse nearly circular shell of emission, with additional bright filamentary emission in the south and northwest that matches the optical and IR emission (Dickel et al 1996).…”

We analyze three Chandra observations, with a combined exposure time of 99 ks, of the Galactic supernova remnant (SNR) RCW 103, a young SNR, with no previous clear detections of metal-rich ejecta. Based on our imaging and spectral analyses of these deep Chandra data, we find evidence for metal-rich ejecta emission scattered throughout the remnant. X-ray emission from the shocked ejecta is generally weak, and the shocked circumstellar medium (CSM) is a largely dominant component across the entire remnant. The CSM component shows abundances of ∼0.5 solar, while Ne, Mg, Si, S, and Fe abundances of the ejecta are up to a few times solar. Comparison of these ejecta abundances with yields from supernova nucleosynthesis models suggests, together with the existence of a central neutron star, a progenitor mass of ∼18-20 M  , though the Fe/Si ratios are larger than predicted. The shocked CSM emission suggests a progenitor with high mass-loss rate and subsolar metallicity.

“…However, the observed correlation of the optical and infrared line emission with the radio filaments suggests that the remnant has reached the Sedov point-blast stage. This is supported by the remnant's polarization structure, which indicates an absence of the radial magnetic field pattern seen in all young double-shock shell remnants (Dickel et al 1996). On this basis, Dickel et al suggest that the remnant has just entered the Sedov stage.…”

We report the detection of the radio pulsar counterpart to the 69 ms X-ray pulsar discovered near the supernova remnant RCW 103 (G332.4−0.4). Our detection confirms that the pulsations arise from a rotation-powered neutron star, which we name PSR J1617−5055. The observed barycentric period derivative confirms that the pulsar has a characteristic age of only 8 kyr, the sixth smallest of all known pulsars. The unusual apparent youth of the pulsar and its proximity to a young remnant requires that an association be considered. Although the respective ages and distances are consistent within substantial uncertainties, the large inferred pulsar transverse velocity is difficult to explain given the observed pulsar velocity distribution, the absence of evidence for a pulsar wind nebula, and the symmetry of the remnant. Rather, we argue that the objects are likely superposed on the sky; this is reasonable given the complex area. Without an association, the question of where is the supernova remnant left behind following the birth of PSR J1617−5055 remains open. We also discuss a possible association between PSR J1617−5055 and the γ-ray source 2CG 333+01. Though an association is energetically plausible, it is unlikely given that EGRET did not detect 2CG 333+01.

Abstract. -A catalogue of supernova remnants in the southern Galaxy within the area 245• ≤ l ≤ 355• , |b| ∼ < 1.5• has been produced from observations made at 0.843 GHz with a resolution of 43 using the Molonglo Observatory Synthesis Telescope (MOST). The catalogue, presented here, provides greyscale images and contour maps of known and newly-discovered remnants. The increased resolution and sensitivity of these observations has resulted in better statistics for southern remnants.
