      Maswanganye, J.P.; Goedhart, S.; Van der Walt, D.J.; Booth, R.S.; Gaylard, M.J. (Oxford University Press, 2015)
      Eight new class II methanol masers selected from the 6.7 GHz Methanol Multibeam survey catalogues I and II were monitored at 6.7 GHz with the 26 m Hartebeesthoek Radio Astronomy Observatory radio telescope for three years ...
    • On the methanol masers in G9.62+0.20E and G188.95+0.89 

      Van der Walt, Diederick Johannes (IOP publishers, 2011)
      A comparison between the observed light curves of periodic masers in G9.62+0.20E and G188.95+0.89 and the results of a simple colliding-wind binary model is made to establish whether the flaring and other time-dependent ...
