THE MOST GALACTIC-CENTER SURVEY .4. SUPERNOVA REMNANT DISTRIBUTION, SMALL-DIAMETER SUPERNOVA-REMNANTS, AND SUPERNOVA REMNANT PULSAR COINCIDENCES

The Molonglo Observatory Synthesis Telescope (MOST) has been used to m ake a new 843-MHz survey of the Galactic Centre region. This paper con siders the effect of the 17 new candidate supernova remnants (SNRs) di scovered on the observed longitude distribution of SNRs in the Galaxy. An excess of SNRs by a factor of 2 in number over that expected for a uniform Galaxy-wide distribution is identified, and the implications are discussed. Also described is a search for small-diameter SNRs in t his region, in which one possible candidate has been found. Finally, t he relationship between the new SNR candidates and known pulsars in th e region is examined, but no compelling evidence is found for a new SN R-pulsar association.
