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.”

UFS honours its sport stars
2008-10-24

 

The UFS's sport stars are, from the left: Robert Ebersohn, junior mens sport star, Boy Soke, Sportsman of the Year, and Mari-Lise Linde, junior women sport star. Adéle Niemand, Sportswoman of the Year, was absent.

 The University of the Free State (UFS) this week honoured its sport stars during the annual Kovsie Sports Dinner, held in Bloemfontein.

Boy Soke, long distance runner who has obtained national colours in all three disciplines of athletics was named Sportsman of the Year. Protea netball player Adéle Niemand was named Sportswoman of the Year for the second consecutive year.

The Cheetah and Springbok sevens rugby player, Robert Ebersohn and netball player Mari-Lise Linde were named junior sport stars.

“The inclusion of five of our students in the South African team that took part in the Beijing Olympic Games is an indication of the standard of sport at the university. We are proud of all our sportsmen and women and salute them for the effort they put in to achieving their goals,” said Mr James Letuka, Director of KovsieSport.

The UFS this year had several other achievements, namely: The inclusion of eight Free State cricket players in the amateur team, the hockey team winning the University Sport South Africa (USSA) B section, the inclusion of three soccer players in the USSA team, rugby winning the USSA competition for the second time, netball winning gold on the USSA tournament for the fourth consecutive year, and the ladies tennis winning the USSA tournament.

The following awards were also made in the university’s different sporting codes during the Kovsie Sports Dinner:

Roné Reyneke: Athletics
Boy Soke: Athletics
Murray Capon: Hockey
Cherie Smith: Hockey
Doretha Joubert: Netball
Riaan Jordaan: Cricket
Wayne Stevens: Rugby
Karin Coetzee: Tennis
Willem Steenkamp: Tennis
Gabisele Hlumbane: Soccer
Lehlohonolo Mofokeng: Soccer
Prof. Martin Dednam: Devoted service to badminton
Sarah Shannon: Special merit award for participating in the Paralympics Games in Beijing

The guest speaker was Dr Derik Coetzee who was the head of Springbok Rugby Team’s conditioning during last year’s Rugby World Cup.
