Abstract (from CDS):

We present a radio analysis of the recently identified supernova remnant G321.3-3.9 using archival multiwavelength data spanning 88-2304 MHz. The source exhibits an elliptical shell-like morphology (1$\mathop{.}\limits^{\unicode{x000b0}}$3 × 1$\mathop{.}\limits^{\unicode{x000b0}}$7) and a relatively flat nonthermal spectral index of α = -0.40 ± 0.03. The distance is estimated using both the Σ-D relation (1.6-2.9 kpc) and tentative associations with H I structures, the latter suggesting a near-side solution of 2.5-3.3 kpc, though the physical connection remains uncertain.
