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 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.”

Department celebrates 50th anniversary

On 13 March the Department Microbial, Biochemical and Food Biotechnology at the University of the Free State (UFS) celebrated its 50th anniversary in a splendid fashion with a lecture entitled, The origin of life: Exactly how did life begin? as part of the Darwin commemorative lecture series, followed by a reunion of current and former staff members and postgraduate students of the department with a barbeque on the following day.

The proceedings were concluded on 14 March with a gala dinner in die Centenary Complex at the UFS attended by 153 staff members, post-graduate students (current and former) and other guests. During the dinner the guests were treated to a presentation of historical photos of the founding and development of the department. Currently the department is one of the largest departments in the Faculty of Natural and Agricultural Sciences in respect of the number of staff members and students as well as research outputs. This is the result of entrepreneurial actions to increase student numbers and research activities, as well as the merging with the smaller Department of Biochemistry in 1988 and more recently with the Department of Food Science in 2002. The department comprises 20 academics, 24 support staff and 65 postgraduate students. It also boasts 12 lecturers with ratings from the National Research Foundation (NRF), which include three academics with a B-rating, an indication of international recognition for their research. The department has the largest number of lecturers with an NRF-rating at the UFS. 

“It was interesting to learn during the reunion of the variety of professions occupied by former students of the department, i.e. at other tertiary educational institutions, the CSSIR, SAPPI, Sasol and a multitude of other industries, as well as at research institutions in the USA and Australia,” said Prof. James du Preez, Head of the Department.
