In the eight months since his appointment Colafrancesco has already assembled the largest astronomy research group in Gauteng and it is growing fast.
In addition to the SKA project, Wits is very active in developing southern Africa as a the place to be for astronomy research using a range of different telescopes, or a multi-frequency approach: Southern Africa already has the optical Southern African Large Telescope (SALT) and Wits is assisting Namibia in bidding for the gamma-ray Cherenkov Telescope Array (CTA).
In addition, Colafrancesco said the Mitra, KAT-7 and MeerKAT telescopes are all part of the bid to host the SKA, so the bidding process itself was worth it for astronomy in South Africa.
These telescopes also show South Africa’s commitment to hosting the SKA. Such projects are absent from Australia, the other bidding country.
Scientifically, South Africa’s site is better, labour costs are cheaper and high-speed internet lines to Europe are already established, said Colafrancesco. He also highlighted many other advantages to building the SKA in Southern Africa rather than in Australia.
The SKA’s decision making committee delayed the expected announcement last week saying it was “important to maximise the value from the investments made by both candidate host regions”.
Colafrancesco agrees with the SKA committee in this but, in his opinion, there is no doubt that South Africa’s site will the best choice for everyone involved.
“It’s not a competition like a rugby match – everyone should win.” He said South Africa’s site combined with Australia’s experience in radio-astronomy makes the most sense for the project.
He said South Africa should remain optimistic about winning the bid because last week’s delay allows the deciding committee to become more aware of South Africa’s advantages and opportunities. “It’s a chance for the world to open their eyes about South Africa.”
