RADIO IMAGES OF THE LARGE MAGELLANIC CLOUD - Professor John R. Dickel Colloquium

We have used the Australia Telescope Compact Array to construct radio
continuum images of the Large Magellanic Cloud at wavelengths of 6 and
3.5 cm with resolutions of 35 and 20 arcsec, respectively (9 and 5 pc
at the 50 kpc distance of the LMC). A total of 6336 mosaic positions
were used to cover an area of 6 degrees on a side. To include the broad
scale emission which cannot be measured by the interferometer, data from
the Parkes 64-meter telescope are also included. In addition, limited
data using the sixth antenna at ~ 6-km baselines are available to
distinguish bright unresolved sources (< 2 and 1.2 arcsec, reespectively).
All of the well known supernova remnants and H II regions are clearly seen
and some new sources are found. Comparisons with various optical and
x-ray catalogs are under way.
