Scientific paper

We propose to image a sample of massive young stellar objects towards which both strong ammonia (1,1) and (2,2) emission has previously been detected. The aim of these observations is to probe the physical conditions of the cores in which massive stars formation is taking place. Ammonia is a dense gas tracer and an excellent probe of the properties of dense cores. We plan to observe the ammonia (1,1), (2,2), (3,3), (4,4), (5,5) and (6,6) inversion transitions. These transitions will allow many key parameters to be calculated for each core, such as the optical depth, column density, temperatures, as well as revealing details of their velocity structure.
