MALT90

The Millimetre Astronomy Legacy Team 90 GHz (MALT90) Survey is a large international project to make molecular line maps of over 2,000 dense cores in the galactic plane. The survey is now complete... The MALT90 survey exploited the fast-mapping capability of the ATNF Mopra 22-m telescope, combined with the new broadband MOPS correlators which allowed the simultaneous imaging of 16 molecular lines near 90 GHz. These molecular lines probe the physical conditions, chemical state, and evolutionary state of over 2,000 dense molecular cores. The target cores were selected to host the early stages of high-mass star formation and to span the complete range of their evolutionary states (from pre-stellar cores, to proto-stellar cores, and on to H II regions). Each core has been mapped simultaneously in 16 molecular lines at excellent angular (40 arcsec) and spectral (0.1 km/s) resolution.
