Periodic variability of the mainline hydroxyl masers in G9.62+0.20E
S. Goedhart, R. van Rooyen, D. J. van der Walt +4
We present the results of a monitoring campaign using the KAT-7 and HartRAO 26m telescopes, of hydroxyl, methanol and water vapour masers associated with the high-mass star forming…
A Masing Event in NGC6334I: Contemporaneous Flaring of Hydroxyl, Methanol and Water Masers
G. C. MacLeod, D. P. Smits, S. Goedhart +7
As a product of the maser monitoring program with the 26m telescope of the Hartebeesthoek Radio Astronomy Observatory (HartRAO), we present an unprecedented, contemporaneous flarin…
Discovery of periodic class II methanol masers associated with G339.986-0.425 region
J. P. Maswanganye, D. J. van der Walt, S. Goedhart +1
Ten new class II methanol masers from the 6.7-GHz Methanol Multibeam survey catalogues III and IV were selected for a monitoring programme at both 6.7 and 12.2 GHz with the 26m Har…
New Periodic 6.7 GHz Class II Methanol Maser Associated with G358.460-0.391
J. P. Maswanganye, M. J. Gaylard, S. Goedhart +2
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 26m Hartebeesthoek Radio Astronomy Obs…
Periodicity in Class II methanol masers in high mass star forming regions
S. Goedhart, J. P. Maswanganye, M. J. Gaylard +1
We report the results of 10 years of monitoring of six regularly varying 6.7 GHz methanol masers using the Hartebeesthoek 26m telescope. Observations were done at intervals of 1--2…
