The APEX Telescope Large Area Survey of the Galaxy (ATLASGAL)

Submillimeter continuum emission traces high molecular column densities and, thus, dense cloud regions in which new stars are forming. Surveys of the Galactic plane in such emission have the potential of delivering an unbiased view of high-mass star formation throughout the Milky Way. The location of the Atacama Pathfinder Experiment (APEX) telescope on the Chajnantor plateau in Chile is ideally suited for mapping the inner Galaxy. After a brief introduction to this telescope and its instruments, our ongoing Galactic plane survey, ATLASGAL, will be described. Its scope, current status and first results will be presented. Aimed at mapping 360 square degrees with a uniform sensitivity of 50 mJy/beam using the Large APEX Bolometer Camera (LABOCA), this survey will provide the first unbiased sample of cold dusty clumps in the Galaxy at submillimeter wavelength - targets for molecular line follow-up observations and high resolution studies with ALMA and the EVLA. Our mid-term strategy for this project will be described, and preliminary results will be shown.
