摘要：

The first observations in a search for H20 masers in southern galaxies involved objects containing previously reported maser emission. The maser in NGC4945 was confirmed, but no emission exceeding 0.5 Jy was detected in NGC 253 or in N159 of the Large Magellanic Cloud. The maser in NGC 4945 is associated with the nucleus of the galaxy and has a luminosity (165Z,©) at least an order of magnitude greater than any maser of our Galaxy. © Royal Astronomical Society.
