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.”

Wayde the next big star, says Michael Johnson

"Usain Bolt will be retiring soon, this could be the next star." That is how the legendary Michael Johnson explained the feat by the Kovsie athlete Wayde van Niekerk. Van Niekerk broke Johnson’s 17-year old world record in the 400m when he won gold in 43.03 at the Olympic Games in Rio de Janeiro on Sunday night (Monday morning, SA time). It was also South Africa’s first track gold medal in 96 years.

Johnson, whose record was beaten by 0.15, described the way in which the 24-year-old South African outperformed the 400m field as ‘a massacre’. The American won two Olympic 400m titles.

"The UFS congratulates Wayde and his youthful coach, our own Tannie Ans.”


"Van Niekerk is so young, what else can he do? Can he go under 43 seconds? It is something I thought I could do, but never did,” Johnson said on www.bbc.com. Van Niekerk thanked Johnson in a BBC Sport interview for setting an example. “I just went out there and did my best tonight,” the BA Marketing student from the University of the Free State (UFS) said.

Greatest UFS achievement in 114 years – Prof Jansen

“This is by far the greatest achievement of any UFS student in 114 years,” said Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS. “And that he broke one of the world’s toughest athletic records with his trademark grace and humility, makes him a role model to millions of South African youth.

“The UFS congratulates Wayde and his youthful coach, our own Tannie Ans.”

The 74-year-old Botha has been coaching Van Niekerk since 2012.  “She's an amazing woman," Van Niekerk said to www.sport24.co.za about her. “I'm just grateful that I can trust in her work and I think it speaks for itself.”

 

"Van Niekerk is so young, what else
can he do? Can he go under
43 seconds?”

Bolt and Twitter full of praise for South African inspiration

Bolt, who won his third consecutive 100m crown in Rio, interrupted his own media interviews at the Olympic stadium to congratulate Van Niekerk.

Twitter also erupted as many praised the UFS star. Gary Player, who is the manager of the SA golf team at the Olympics, tweeted:  “What a run! What a man! Congrats @WaydeDreamer #proudlySA #GOLDMEDAL #RSA”.

AB de Villiers, the South African One Day International cricket captain, also congratulated him: “What a special feeling waking up to the news of @WaydeDreamer winning the 400m and breaking the world record. Great inspiration to so many!”
