Abstract
dc.description.abstract
The Millimetre Astronomy Legacy Team 90 GHz (MALT90) survey aims to characterise the physical and chemical
evolution of high-mass star-forming clumps. Exploiting the unique broad frequency range and on-the-fly mapping
capabilities of the Australia Telescope National Facility Mopra 22 m single-dish telescope1, MALT90 has obtained 3 × 3
maps towards 2 000 dense molecular clumps identified in the ATLASGAL 870 μm Galactic plane survey. The clumps
were selected to host the early stages of high-mass star formation and to span the complete range in their evolutionary
states (from prestellar, to protostellar, and on to H II regions and photodissociation regions). Because MALT90 mapped 16
lines simultaneously with excellent spatial (38 arcsec) and spectral (0.11 km s−1) resolution, the data reveal a wealth of
information about the clumps’ morphologies, chemistry, and kinematics. In this paper we outline the survey strategy,observing mode, data reduction procedure, and highlight some early science results. All MALT90 raw and processed
data products are available to the community. With its unprecedented large sample of clumps, MALT90 is the largest
survey of its type ever conducted and an excellent resource for identifying interesting candidates for high-resolution
studies with ALMA.
