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 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.”

International ties for OSM

Prof Nicol Viljoen in the historic Teatr Zdrojowy in Walbrzych, Poland
20 August 2013


Profs Nicol and Martina Viljoen from the Odeion School of Music (OSM) recently undertook a very successful trip to Europe where Prof Nicol Viljoen rendered two solo piano recitals in Poland. They also delivered a joint paper at a congress in Budapest.

The first of the two recitals were held in Crakow at the famed Zespol Panstwowych School of Music. At this event, Prof Viljoen essentially recited Chopin Mazurkas and was invited to repeat this performance in Poland in the future.

The second piano recital was in the historicTeatr Zdrojowy im. Henryka Wieniawskiego in Walbrzych. This concert included Preludes, Mazurkas, as well as the Ballad in G minor by Chopin. After the Mazurkas, the audience rewarded Prof Viljoen with a standing ovasion – and again at the end of the concert. As a result of this, the chief organiser of the event, Jerzy Kosek, who is also the conductor of the Filharmonia Sudecka, invited Prof Viljoen to perform as soloist with his orchestra next year.

Kosek also invited Conducting students at the OSM to work with the Filharmonia under his leadership on an exchange basis. He indicated that he would like to strengthen the ties with the University of the Free State and the Odeion School of Music. Two members of the Filharmonia Sudecka are currently doctoral students in Performing Arts at the OSM, namely Karol Legierski (concertmaster) and Marianne Cilliers (first violin), while the co-concertmaster, Dorota Graca, is in the process of registering for doctoral studies at the OSM.

The paper delivered by Profs Viljoen in Budapest, formed part of the interdisciplinary congress, ‘The Arts in Society,’ where more than twenty countries were represented. Their paper dealt with the post-apartheid oeuvre of the South African composer, Hans Huyssen. Charla Schutte, another doctoral student at the OSM, delivered a paper on an interpretation of indoctrination songs on the basis of an analytical model by the philosopher Johann Visagie.

During the trip, Prof Martina Viljoen also had a productive meeting with the executive manager of Common Ground Publishers, an academic publisher based in the USA, with a view to publish work from the OSM.
