"The Millimeter Astronomy Legacy Team 90 GHz Survey (MALT 90)"

Abstract. I present results from the first two years of the MALT 90 Survey, a multi-line survey of molecular emission from dense, high-mass star-forming cores. MALT90 uses the Mopra 22-m telescope in Australia to map simultaneously 16 molecular lines at ~3 mm wavelength toward a sample of dense cores identified by the 870 micron ATLASGAL continuum survey. I will describe three early results from the first two years of survey data of about 1200 cores: (1) a technique to find distances and Galactic structure, (2) the discovery of greatly varying chemical composition and its relation to protostellar evolution, and (3) the extension of the Gao and Solomon relation between molecular line and infrared luminosity, first established for galaxies, to the scale of individual cores.
