The Next Generation of High-Mass Stars and Clusters Traced by ATLASGAL

International audience; The Atacama Pathfinder Experiment (APEX) telescope is ideally located to observe the inner part of our Galaxy. With its good sensitivity, the LABOCA bolometer array can map hundreds of square degrees at λ = 870 μ m λ = 870 \upmu m in a reasonable time. ATLASGAL, the APEX Telescope Large Area Survey of the Galaxy, covers 420 deg2 of the inner Galactic plane, with a typical rms noise of 50 mJy/beam. The data reveal thousands of compact sources, as well as giant molecular complexes and large scale filamentary structures. Many follow-up projects are ongoing, and more are planned e.g. with ALMA.
