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.

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 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.”

School of Medicine not closing
2009-10-22

There is no immediate threat that the University of the Free State’s (UFS) School of Medicine will be closing.

This was confirmed by Prof. Gert van Zyl, Head of the UFS’s School of Medicine and acting Dean of the Faculty of Health Science, following media reports that Prof. Andries Stulting has indicated in a meeting with other medical schools and parliamentary standing committee members that the School will have to close due to the serious problems in the health sector.

“This discussion should be seen in context. Prof. Stulting, in his capacity as acting Head of the School of Medicine, and on behalf of the School and the Faculty, sent a proactive warning to the Free State Health Department, the Member of the Executive Committee and the Premier of the Free State regarding the long-term consequences of the health crisis. This statement was not interpreted correctly. Everything that Prof. Stulting said has already been included in the position statement that the School released in May 2009. What is urgent, though, is that the problems that were identified at especially Pelonomi Hospital in May this year were still not addressed,” said Prof. Van Zyl.

According to Prof. Van Zyl, problems at Pelonomi Hospital include not enough beds, lack of funding for the health sector in the Free State and in some instances problems with filling vacant positions.

“Some of these problems have already been addressed by the Free State Department of Health. Our training platform includes not only Pelonomi Hospital, but also Universitas Hospital, National Hospital, the Free State Psychiatric Complex and several clinics in the Bloemfontein area. This means that there are other facilities available that function in order to provide appropriate training to undergraduate students. Therefore, training is not in immediate danger and the School will definitely not be closing,” he said.

“New first-year students will start their studies in 2010 and I can assure you that there will be adequate training opportunities to take in and train students. However, we do struggle with a bigger intake as requested by Government. I want to put Prof. Stulting’s remark in context: He referred to postgraduate students and therefore the specialists who are in training,” said Prof. Van Zyl.

According to Prof. Van Zyl the specialists in training is a problem that was discussed with the Free State Health Department – with specific reference to less time in operating theatres and the number of beds at Pelonomi Hospital. “We are of the opinion that, should the Department address this problem as a matter of urgency, there will be no long-term damage to the training of these specialists in training. These are the students that Prof. Stulting was referring to,” he said.

The School received more than 1 500 applications for undergraduate studies in 2010 – all of these applications met the minimum selection requirements for the 140 available places. “Our current undergraduate students are therefore not influenced and they will continue to receive the quality training for which the School is renowned,” he said.

Prof. Jonathan Jansen, Rector and Vice-chancellor of the UFS, is aware of this and he satisfied himself as to the situation when he visited the hospitals in Bloemfontein on Friday, 9 October 2009. The national Minister of Higher Education and Training, Dr Blade Nzimande, was also informed of the School’s concerns when he visited the UFS in September 2009.
