Paper Abstract

The high optical quality of ESO's ISAAC instrument at the 8.2-m ANTU VLT telescope and the good observing conditions at the Paranal site allow very detailed studies of southern massive star-forming regions. Our observations revealed their large degree of complexity. By means of near- and thermal-infrared images we performed a thorough characterisation of the embedded stellar population. Imaging polarimetry provided clues on the spatial distribution of the dust grains and the illuminating sources. Special emphasis was put on the most massive objects, young luminous stars that cause ultracompact HII regions.
