Supernova remnant candidates in the Small Magellanic Cloud

Abstract
Eighteen SNR candidates in the SMC deriving from X-ray, optical and radio observations have been examined at a frequency of 843 MHz. Six SNRs are confirmed, all with flux densities far above the radio detection limit. Other identified radio sources from this sample include a quasar and an emission nebula. Comparison with Galactic SNRs suggest differences in the ΣD and ND relations, but the number of SNRs in the present sample is too small for good statistics. The birthrate of SNRs in the SMC is roughly estimated as ~ 1 every 1000 yr.
