(2010)
      We have conducted a Galactic plane survey of methanol masers at 6668 MHz using a seven-beam receiver on the Parkes telescope. Here we present results from the first part, which provides sensitive unbiased coverage of a ...

    • The 6-GHz methanol multibeam maser catalogue – II. Galactic longitudes 6° to 20° 

      Green, J.A.; Caswell, J.L.; Fuller, G.A.; Avison, A.; Breen, S.L.; Ellingsen, S.; Gray, M.D.; Pestalozzi, M.; Quinn, L.; Thompson, M.A.; Voronkov, M. (2010)
      We present the second portion of an unbiased survey of the Galactic plane for 6668-MHz methanol masers. This section of the survey spans the longitude range 6° to 20°. We report the detection of 119 maser sources, of which ...

      Green, J.A.; Caswell, J.L.; Fuller, G.A.; Avison, A.; Breen, S.L.; Brooks, K.; Burton, M.; Chrysostomou, A.; Cox, J.; Diamond, P.J.; Ellingsen, S.; Gray, M.D.; Hoare, M.G.; Masheder, M.R.W.; McClure-Griffiths, N.; Pestalozzi, M.; Phillips, C.; Quinn, L.; Thompson, M.A.; Voronkov, M.; Walsh, A.; Ward-Thompson, D.; Wong-McSweeney, D.; Yates, J.A.; Cohen, R.J. (2009)
      A new 7-beam 6−7 GHz receiver has been built to survey the Galaxy and the Magellanic Clouds for newly forming high-mass stars that are pinpointed by strong methanol maser emission at 6668 MHz. The receiver was jointly ...

    • Major structures of the inner galaxy delineated by 6.7 GHz methanol masers 

      Green, J.A.; Caswell, J.L.; McClure-Griffiths, N.; Avison, A.; Breen, S.L.; Burton, M.; Ellingsen, S.; Fuller, G.A.; Gray, M.D.; Pestalozzi, M.; Thompson, M.A.; Voronkov, M. (2011)
      We explore the longitude-velocity distribution of 6.7 GHz methanol masers in the context of the inner structure of our Galaxy. We analyze the correlation in velocities within this distribution and identify density enhancements ...
