New robotic telescope gives UFS edge over international astronomy groups

13 May 2022 | Story Leonie Bolleurs | Photo Leonie Bolleurs

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.”

King Moshoeshoe comes alive on national television

2004-11-02

The ground-breaking documentary film on the life and legacy of King Moshoeshoe, the founder of the Basotho nation, will come alive on Thursday 4 November 2004 when it is screened on SABC2 at 21:00

The film, called Moshoeshoe: The Renaissance King, forms part of a larger project by the University of the Free State (UFS) to honour the Moshoeshoe legacy of nation-building and reconciliation and to explore his role as a model of African leadership. It was produced by the well-known journalist Mr Max du Preez and commissioned by the UFS as part of its centenary celebrations.

The SABC2 screening was preceded by a première in Bloemfontein last month, and was attended by provincial political leaders.

This past weekend there was a première at the Royal Palace in Lesotho, which was attended by King Letsie III, the prime minister, the chief justice, judges, the president of the senate, cabinet ministers and directors-general.

“Through this documentary film the UFS commits itself to developing a shared appreciation of the history of this country and to the establishment of the Free State Province as a model of reconciliation and nation-building. King Moshoeshoe is also a strong common element, and binding factor, in the relationship between South Africa/the Free State, and its neighbour, Lesotho,” said Prof Frederick Fourie, Rector and Vice-Chancellor of the UFS.

“Not all people in South Africa know the history of Moshoeshoe. Many Basotho – but not all – are well versed in the history of Moshoeshoe, and his name is honoured in many a street, town and township. Many white people know little of him, or have a very constrained or even biased view of his role and legacy. In Africa and the world, he is much less known than, for instance, Shaka,” said Prof Fourie.

“King Moshoeshoe did a remarkable thing in forging a new nation out of a fragmented society. He also created a remarkable spirit of reconciliation and a remarkable spirit of leadership,” said Prof Fourie.

According to Prof Fourie we already benefit from his legacy: the people of the Free State share a tradition of moderation and reconciliation rather than one of aggression and domination. “For the UFS this is also part of real transformation – of creating a new unity amidst our diversity,” said Prof Fourie.

“We also find in the legacy of King Moshoeshoe the possibility of a “founding philosophy”, or “defining philosophy”, for the African renaissance. To develop this philosophy, we must gain a deeper understanding of what really happened there, of his role, of his leadership. Therefore the UFS will encourage and support further research into the history, politics and sociology of the Moshoeshoe period, including his leadership style,” said Prof Fourie.
