“…Optical arcs on the southern and north-western borders coincide with the regions of greatest radio brightness. X-ray observations (Nugent et al 1984;Seward 1990) show that the remnant is also a strong source of X-ray emission. The Einstein Observatory HRI image of Seward (1990) shows a clear X-ray shell with a brightness distribution similar to the radio and optical.…”

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.

“…Xing et al (2014) have also recently reported a likely γ-ray detection with Fermi. Its age is estimated as ∼2000 years (Nugent et al 1984;Carter et al 1997), and a number of studies suggest a distance of ∼3.3 kpc (Westerlund 1969;Caswell et al 1975;Nugent et al 1984;Reynoso et al 2004;Paron et al 2006). The presence of a central object (Tuohy & Garmire 1980) indicates a core-collapse origin.…”

“…X-ray observations also reveal a nearly circular shell ∼8′ in diameter, similar in morphology to the diffuse radio emission. Nugent et al (1984), using Einstein observations, fit non-equilibrium ionization plasma models to the X-ray spectrum and found Mg, Si, S, and Fe abundances near solar, leading them to conclude that the X-ray emission is primarily due to shocked interstellar medium. The IR analysis of Oliva et al (1999) also found no enhanced abundances.…”

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.

“…RCW103 RCW103 is a young supernova remnant with a quasi-circular morphology (9 ) and an associated X-ray source (Gotthelf & Vasisht 1997). Nugent et al (1984) estimate it is 1000 years old, in agreement with its large velocity dispersion (900 km s −1 , Tuohy et al 1979), and the coincidence between optical filaments and a radio shell. Caswell & Haynes (1975) used HI absorption lines to deduce a distance of 3.3 kpc.…”

Abstract. The Galactic plane has been observed between l = 330• to l = 336• as part of a velocity resolved Hα survey of the southern Milky Way using a scaning Fabry-Perot on a 36 cm telescope. The detailed analysis of the resultant Hα profiles reveals the presence of several layers of ionized gas with different velocities over the surveyed region. We have studied in detail both the 2-D spatial and velocity structure of the HII regions RCW102, RCW104 and RCW106. Combining these Hα observations with stellar and radio data we provide estimates for the most probable distances of these different layers. The first layer at −5 km s −1 is local emission linked to the Sco-Cen association at 170 pc. The next layer, around −24 km s −1 , is at 1.9 kpc and traces the near section of the Sagittarius-Carina arm. Well connected to the Sagittarius-Carina arm portions traced in the adjacent regions (l = 328• and l = 338 • area), the arm, in this longitude range, clearly shows and confirms the departure from a logarithmic spiral. The Scutum-Crux arm is also traced in this area by faint and diffuse emission at −40 km s −1 which can be placed at 3.2 kpc. The layer at −52 km s −1 is the major spiral-arm feature of the studied area; its most probable stellar distance is 4.2 kpc. An important emission component is also observed at −65 km s −1 in the southern part of the surveyed area. This mainly patchy and filamentary emission we identify as the possible optical counterpart of a supernovae remnant centered at l = 332.0• , b = −3.2 • . Finally, two complexes have been determined around 12.5 kpc which places them in the far section of the Norma arm.
