Molecules with Mopra
Urquhart et al. have used the Mopra 22m telescope to conduct a 3-mm molecular-line survey towards 570 high-mass star-forming clumps. The sample was selected from the 10,000 clumps identified by the ATLASGAL survey and includes the key evolutionary stages associated with massive star formation. The observations were made over the frequency range of 85.2 to 93.4 GHz with a velocity resolution of ∼0.9 km/s and detected emission from 26 different transitions. The image above shows the number of detections across the sample of 570 sources for these 26 different spectral lines. More details are given in the paper published in Monthly Notices of the Royal Astronomical Society.
