The Astrophysics Research Group in the UFS Department of Physics recently collaborated with the Institute of Astrophysics of Andalusia (IAA) in Spain and the University College of Dublin (UCD) in Ireland, to install a robotic telescope at the Boyden Observatory. Pictured here, are from the bottom, Teboho Rakotsoana and Simon Rakotsoana from the UFS; Emilio J Garcia from the Institute of Astrophysics of Andalusia; Prof Pieter Meintjes; and Prof Antonio M Carrillo from UCD.

The Astrophysics Research Group in the Department of Physics at the University of the Free State (UFS) is part of an international collaboration with the Institute of Astrophysics of Andalusia (IAA) in Spain and the University College of Dublin (UCD) in Ireland, which focuses on measuring the brightness of transient sources. Knowledge gained from studying these cosmic X-ray sources, which seem to appear in the sky for a short time before disappearing, will lead to a more complete and better understanding of the universe, believes Prof Pieter Meintjes, Professor of Physics and Head of the Astrophysics Programme in the Department of Physics.

To facilitate these observations, a robotic telescope network has been established, with the Boyden Observatory selected as one of the sites for BOOTES 6 (a Burst Observer and Optical Transient Exploring System).

The UFS and the IAA started working on this project more than two years ago. The foundation and pier were built through a local tender, and in January 2020, part of the dome of the structure housing the telescope arrived by ship. Due to the COVID-19 pandemic there were some delays, resulting in the crew from Spain only arriving in South Africa with the telescope and hardware in November 2021, but having to return to their country without completing the installation. They returned in April, and in early May completed assembling the telescope in collaboration with UFS researchers and technicians.

Robotic telescope opportunity to further own research

The main scientific objective of the robotic telescope is to observe and monitor the optic counterparts of gamma-ray bursts as quickly as possible when detected from space or other ground-based observatories.

Prof Meintjes says they will use the telescope to observe these transient sources that goes into an eruptive phase for a short span of time. “Since BOOTES has an enormously fast slew rate, it can start observations of erupting sources within a few seconds, which allows the Astrophysics Research Group to get data very quickly. This will certainly give us an edge over other international astronomy groups that are also involved in the same type of research,” says Prof Meintjes, the local coordinator of the project who is overseeing the whole operation locally. 

He explains the importance of monitoring these packets of enormous energy. “By observing the optical afterglow of the gamma-ray bursts, we can establish its point of origin in space. Furthermore, the shape of the optical afterglow light curve gives insight into the type of mechanism behind the gamma-ray burst, i.e., whether the burst is produced by a collision between two neutron stars or by the explosion of a hypernova event.” 

The knowledge gained with research made possible by the robotic telescope will lead to a more complete and better understanding of the universe. – Prof Peter Meintjes

The UFS Astrophysics Research Group, with its research focus on high-energy astronomy and the physics behind gamma-ray bursts, has a particular interest in this project. As the local custodians of the project and in terms of a memorandum of understanding, the group is guaranteed a certain amount of telescope time for its own in-house observation programmes.

Project expands UFS’ international research footprint

Besides the opportunity for knowledge exchange, this project establishes Bloemfontein as a region where research of international quality is being done and will help to attract talented learners to the UFS. “The successful operation of the robotic telescope may also draw more international groups to bring robotic telescopes to Boyden, thus expanding our international research footprint,” he adds. 

The fact that the Boyden Observatory is in the Southern Hemisphere and has access to the galactic centre region with its host of very interesting astronomical objects and the Magellanic Clouds, makes it a very attractive site for astronomical research,” says Prof Meintjes.

“We also have a number of years of experience in robotic telescopes in the sense that we have been hosting the Watcher telescope, operated by the University College Dublin in Ireland, since 2001. Once mounted in middle May 2022, this will then be Boyden’s second robotic telescope.”

Kovsies included in national team for 2015 World Cup in Australia

The success of netballers Adele Niemand (former Kovsie) and Karla Mostert (captain of the Kovsie netball team) continues - they represent Kovsies, the provincial Crinums, as well as the national SPAR Proteas as goal-keeper and goal defender, respectively. The UFS is also very proud of their inclusion in the national team for the upcoming 2015 World Cup in Australia.
 
On 6 June 2015, Niemand and Mostert played for the Free State Crinums, who overpowered the Gauteng Jaguars in the Brutal Fruit Netball Premier League (NPL). This win secured the championship title for the Crinums for the second time in a row.
 
“Our aim was to improve with each game. We did this throughout the league. The final game against the Jaguars was definitely our best game, so we are very satisfied. The NPL prepared us and gave us game time, which I think, is great preparation for the Diamond Challenge,” said Mostert.
 
Niemand and Mostert represented South Africa at the Diamond Challenge in Margate from 14 to 18 June 2015.
 
Prior to the event, Burta de Kock, Head Coach of the university’s team, said, “The Diamond Challenge in Margate will be hard, because Zambia, Uganda and Malawi want to be the best in Africa. But SA has enough brilliant players to do the trick for us, and we also have a great leader as captain.”
 
Niemand and Mostert form part of the national squad selected for the upcoming 2015 World Cup in Australia. Kovsie Lauren-Lee Christians from the UFS is the only non-travelling substitute for the World Cup. In their group, the team will compete from 7 to 16 August 2015 against Malawi, Singapore and Sri Lanka.
 
For the upcoming games against the world’s best in Sydney, Niemand has set a personal goal, namely to be the best by playing every game as if it's her last, and in so doing, aims to maintain the high standard of the team.
 
Their coach’s words of encouragement for the World Cup are: “Just go out with passion and enjoy every second. Never forget you are our CHAMPS!!”
 
The SPAR Proteas have indeed proven to be champions by beating Zambië 63 - 38 in the opening match of the challenge on 16 June 2015 at the UGU Sports Centre. They continued to beat Malawi convincingly by 43 - 33, and thrashed Uganda with a score of 56 - 39 to maintain their unbeaten run. The Proteas managed to uphold their lead to the end and thereby secured the tournament trophy win a win of 40 - 35.  In the first two games against Zambia and Malawi, Mostert and Niemand was respectively Player of the Match.
 
The UFS is also proud of Maryka Holtzhausen, a former Kovsie now captaining the Proteas. Ilze du Pisanie, also a former Kovsie, is the conditioning coach for the Proteas.
