Scientific paper

We have started a survey of high mass star forming regions in the southern hemisphere, to study the different evolutionary stages these cores are in. Out of this survey, we have successfully imaged the three sources with the richest submm spectra with tha ATCA at 3mm. This synthesis between the high resolution ATCA studies and the highly excited line emission from APEX lets us probe into the innermost regions of the hot cores. Nevertheless we need more information on the spectral energy distribution to understand the nature of the continuum emission. Therefore, we propose to observe these cores at 42GHz and 24GHz in two configurations to image the continuum, since it is in these wavelength regions that the relative contributions of dust emission versus free free radiation become apparent and it is possible to detect and characterise UCHII regions embedded in the sources. We will observe at two different frequencies within each band to improve both sensitivity and most importantly the uv coverage of the data through multifrequency synthesis. This proposal is a complete revision of proposal C1764, taking into account the results of our LABOCA 345 GHz observations and the recently published cm data of Urquhart et al. (2007).
