The SuperMALT Project

We present the current status of the SuperMALT, a follow up of the MALT90 project which observed ~3200 clumps in 16 molecular lines near 90GHz (mostly, J=1 - 0) using MOPRA telescope. SuperMALT uses APEX telescope to observe a subsample of 76 massive dense clumps at different evolutionary stages (Pre-stellar to HII regions) in higher J transitions (J=3-2 &4-3) of different molecular species (e.g. N2H+, HCO+, HCN, HNC, H13CO+). Combining the low & high J transition line data, we aim to characterize the physical and chemical properties of the clumps as they evolve
