Thermal emission from dust at submillimetre wavelengths is a direct tracer of high column densities and, thus, of dense cloud regions in which new stars are forming. Surveys of the Galactic Plane in thermal dust emission have the potential to deliver an unbiased view of high-mass star formation throughout the Milky Way. The Atacama Pathfinder Experiment (APEX) telescope is ideally located for mapping the inner Galaxy. Using the Large APEX Bolometer Camera (LABOCA), we have recently completed the APEX Telescope Large Area Survey of the Galaxy (ATLASGAL). This survey, which covers 360 square degrees at 870 µm, provides the first unbiased sample of cold dusty clumps in the Galaxy at submillimetre wavelengths and reveals the clumpy structure of the cold interstellar medium over very large scales that have previously been little explored.

Abstract
Thermal emission from dust at submillimetre wavelengths is a direct tracer of high column densities and, thus, of dense cloud regions in which new stars are forming. Surveys of the Galactic Plane in thermal dust emission have the potential to deliver an unbiased view of high-mass star formation throughout the Milky Way. The Atacama Pathfinder Experiment (APEX) telescope is ideally located for mapping the inner Galaxy. Using the Large APEX Bolometer Camera (LABOCA), we have recently completed the APEX Telescope Large Area Survey of the Galaxy (ATLASGAL). This survey, which covers 360 square degrees at 870 µm, provides the first unbiased sample of cold dusty clumps in the Galaxy at submillimetre wavelengths and reveals the clumpy structure of the cold interstellar medium over very large scales that have previously been little explored.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
