THE MOST GALACTIC-CENTER SURVEY .2. NEW RESULTS ON PUBLISHED SUPERNOVA-REMNANTS AND G2.4+1.4

Within the boundaries of the recent Molonglo Observatory Synthesis Tel escope (MOST) 843-MHz survey of the Galactic Centre, there are 10 obje cts currently believed to be supernova remnants. This paper discusses the new MOST results on these objects. All but one were found to have properties consistent with earlier work. The exception, G358.4-1.9, wa s instead found to have characteristics suggesting a thermal origin. A lso discussed is G2.4+1.4, a shell-like object which has been reported to have a non-thermal radio spectrum. This is at odds with other indi cators which favour a thermal, mass-loss bubble model. The reported sp ectrum is here shown to be in error, with the new data implying a spec tral index of alpha=-0.13 (S-v proportional to v(alpha)). This removes the last existing evidence for a non-thermal radio emission mechanism for this object.
