High-sensitivity survey of NH3 in the Southern Hemisphere

Microwave emission associated with the para form of ammonia, in the (1, 1) line, was searched for in the direction of 46 southern sky positions where strong H2CO absorption or strong H2O maser emission was observed previously. The results of those observations are presented with 17 new ammonia sourc...

Description
Summary:Microwave emission associated with the para form of ammonia, in the (1, 1) line, was searched for in the direction of 46 southern sky positions where strong H2CO absorption or strong H2O maser emission was observed previously. The results of those observations are presented with 17 new ammonia sources discovered.
