A radio continuum survey of the Magellanic Clouds.
Abstract
Details of the Large (LMC) and Small (SMC) Magellanic Clouds have been refined since 1981 through scans on the Molonglo Observatory Synthesis Telescope (MOST). The instrument works in a rotational mode at an 843 MHz operating frequency and a basic field size, defined by a comb of fan beams, of 23 x 23 cosec(delta) arcmin. The campaigns have revealed SNR, emission nebulae and unresolved background quasars/radio galaxies in the SMC. Scans have found 27 SNR in the LMC, all with radii below 40 pc. A distance scale has been devised from the SNRs observed and has been applied to galactic calibrators as a replacement for the luminosity scale. The scale will be applied to quantify a distance to the Clouds and to the galactic center.
