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…
Radio astronomy in Africa: the case of Ghana
Bernard Duah Asabere, Michael Gaylard, Cathy Horellou +2
South Africa has played a leading role in radio astronomy in Africa with the Hartebeesthoek Radio Astronomy Observatory (HartRAO). It continues to make strides with the current sev…
Very Long Baseline Interferometry with the SKA
Zsolt Paragi, Leith Godfrey, Cormac Reynolds +79
Adding VLBI capability to the SKA arrays will greatly broaden the science of the SKA, and is feasible within the current specifications. SKA-VLBI can be initially implemented by pr…
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…
Design, Environmental and Sustainability Constraints of new African Observatories: The example of the Mozambique Radio Astronomy Observatory
Domingos Barbosa, Claudio Paulo, Valerio A. R. M. Ribeiro +9
The Mozambique Radio Astronomy Observatory (MRAO) will be a first milestone towards development of radioastronomy in Mozambique. Development of MRAO will constitute a preparation s…
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…
