HI SEARCHES IN THE ZONE OF AVOIDANCE - PAST AND PRESENT (AND FUTURE)

In the regions of highest optical obscuration and infrared confusion, only 21-cm emission can be used to find galaxies in the Zone of Avoida nce. A feasibility study conducted with the 300-ft telescope successfu lly uncovered galaxies which seem to be consistent with populations of optically-selected low surface brightness galaxies. A complete survey is currently being conducted in the north with the Dwingeloo telescop e. The big breakthrough should come in the south, however, with the ad vent of the Parkes telescope multibeam system.
