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.”

Moshoeshoe Memorial Lecture to focus on Leadership challenges

Lecture to focus on Leadership challenges

n Thursday 25 May 2006 – Africa Day – the University of the Free State (UFS) will host the inaugural King Moshoeshoe Memorial Lecture in honour of this great African leader and nation-builder.

Prof Njabulo Ndebele, internationally renowned writer and academic, and Vice-Chancellor of the University of Cape Town (UCT), will deliver the inaugural lecture at the Main Campus in Bloemfontein on the topic: Reflections on the Leadership Challenges in South Africa.

“I see the lecture as part of a larger debate on leadership models, particularly the concept of African leadership, as well as the ongoing discourse about nation-building and reconciliation,” says Prof Frederick Fourie, Rector and Vice-Chancellor of the UFS.

According to Prof Fourie, the Moshoeshoe project was launched at the UFS in 2004 to coincide with South Africa’s first decade of democracy and was part of the University’s centenary celebrations, having been founded in 1904.

“Through this project the UFS seeks to honour a great African leader and demonstrate our commitment to transformation so as to create a truly inclusive and non-racial university,” said Prof Fourie.

“As the founder of the Basotho nation, King Moshoeshoe is widely credited for his exceptional style of leadership, displaying the characteristics of diplomacy, reconciliation and peaceful co-existence in his efforts to unite diverse groups into one nation,” said Prof Fourie.

As part of its ongoing Moshoeshoe project, the UFS commissioned a television documentary programme on the life and legacy of King Moshoeshoe. This was completed in 2004 and broadcast on SABC 2 later that year.

Abridged curriculum vitae of Njabulo S Ndebele

Professor Njabulo S Ndebele is currently Vice-Chancellor and Principal of UCT.

Njabulo Ndebele began his term of office at UCT in July 2000, following tenure as a scholar in residence at the Ford Foundation’s headquarters in New York. He joined the Foundation in September 1998, immediately after a five-year term of office as Vice-Chancellor and Principal of the University of the North in Sovenga, at the then Northern Province. Previously he served as Vice-Rector of the University of the Western Cape. Earlier positions include Chair of the Department of African Literature at the University of the Witwatersrand; and Pro-Vice-Chancellor, Dean, and Head of the English Department at the National University of Lesotho.

An established author, Njabulo Ndebele recently published a novel The Cry of Winnie Mandela to critical acclaim. An earlier publication Fools and Other Stories won the Noma Award, Africa’s highest literary award for the best book published in Africa in 1984. His highly influential essays on South African literature and culture were published in a collection Rediscovery of the Ordinary.

Njabulo Ndebele served as President of the Congress of South African Writers for many years. As a public figure he is known for his incisive insights in commentaries on a range of public issues in South Africa. He holds honorary doctorates from Universities in the Netherlands, Japan, South Africa and the United States of America. He is also a Fellow of UCT.

Njabulo Ndebele is also a key figure in South African higher education. He has served as Chair of the South African Universities Vice-Chancellor’s Association from 2002-2005, and served on the Executive Board of the Association of African Universities since 2001. He has done public service in South Africa in the areas of broadcasting policy, school curriculum in history, and more recently as chair of a government commission on the development and use of African languages as media of instruction in South African higher education. He recently became President of the Association of the AAU and Chair of the Southern African Regional Universities Association (SARUA).
