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

ATNF Marsfield Lecture Theatre

Abstract

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.
