New robotic telescope gives UFS edge over international astronomy groups

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.”

RAG resilience shines despite rain

2017-02-07

Although the 75th RAG festivities were challenged by ominous weather, in true Kovsie spirit students and organisers still made a gleaming success of the day.

Students help to create sunny feeling
On 6 February 2017, the annual float-building activities culminated in the handing over of schoolbags to 150 learners from schools in and around Bloemfontein. This took place at the Rag Farm on the Bloemfontein Campus of the University of the Free (UFS), since the morning procession to Twin City Mall in Heidedal had to be cancelled due to bad weather.

“It is of course a huge disappointment to all of us that the events had to be cancelled, but we are grateful for the rain,” said Karen Scheepers, Head of Kovsie Rag Community Service and Assistant Director: Student Affairs.

The evening KFC Rag procession took place as planned, with students having the option of taking part despite the weather. Unfortunately, the Chevrolet Music Festival had to be cancelled.

“The very important actors of today are our students who have worked long hours to build the floats and who have worked together to make this rainy day on the outside feel sunny inside,” said Prof Francis Petersen, incoming UFS Vice-Chancellor and Rector, when he addressed the crowd at the Rag Farm. Prof Petersen will take up office on 1 April 2017.

Armentum, Vergeet-My-Nie, and Emily take honours
Armentum, Vergeet-My-Nie, and Emily Hobhouse were the overall winners of the 2017 Rag float-building. “It was worth the hard work. Always remember to ask for advice during float-building,” said Pieter Kotze, RC Rag of Armentum residence on the Bloemfontein Campus. “I also want to thank both the RC Rag from Vergeet-My-Nie and Emily Hobhouse.”

The float theme was Proudly South African, and the winning float encapsulated it with local flavours such as Chappies, a Rooibos tea box and a Lion matchsticks box. They also went the extra mile by incorporating each hostel’s logo within a Chappie design.

The Central Rag Committee would like to thank all their sponsors who made the events possible. The Rag Coronation Ball will take place on 17 February 2017, where the new Rag Queen and Mr Rag will be crowned.
