ATLASGAL -- Relationship between dense star forming clumps and interstellar masers

S. J. Billington, J. S. Urquhart, C. König +10

We have used catalogues from several Galactic plane surveys and dedicated observations to investigate the relationship between various maser species and Galactic star forming clump…

ATLASGAL -- physical parameters of dust clumps associated with 6.7 GHz methanol masers

S. J. Billington, J. S. Urquhart, C. Konig +9

We have constructed the largest sample of dust-associated class II 6.7 GHz methanol masers yet obtained. New measurements from the the Methanol MultiBeam (MMB) Survey were combined…

Environmental conditions shaping star formation: The Carina Nebula

Yanett Contreras, David Rebolledo, Shari L. Breen +2

Using the Mopra telescope, we have targeted 61 regions in the Carina Nebula, covering an area of 1.5 square degrees, of bright and compact 870 m dust continuum emission for mole…

The 6-GHz multibeam maser survey III: comparison between the MMB and HOPS

S. L. Breen, Y. Contreras, S. P. Ellingsen +8

We have compared the occurrence of 6.7-GHz and 12.2-GHz methanol masers with 22-GHz water masers and 6035-MHz excited-state OH masers in the 100 square degree region of the souther…

6.7GHz Methanol Maser Associated Outflows: An evolutionary sequence

H. M. de Villiers, A. Chrysostomou, M. A. Thompson +8

We present a continuing study of a sample 44 molecular outflows, observed in 13CO lines, closely associated with 6.7GHz methanol masers, hence called Methanol Maser Associated Outf…

First cosmological constraints on the proton-to-electron mass ratio from observations of rotational transitions of methanol

S. P. Ellingsen, M. A. Voronkov, S. L. Breen +1

We have used the Australia Telescope Compact Array to measure the absorption from the 2(0) - 3(-1}E 12.2 GHz transition of methanol towards the z=0.89 lensing galaxy in the PKS B 1…
