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 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.”

The University of the Free State received its third A-rating from the National Research Foundation (NRF) when Prof Jonathan Jansen was awarded an A2-rating.

Prof Jansen is a Senior Research Professor in Education secondary research field and field of specialisation: Development education and Curriculum theory at the UFS Faculty of Education and Fellow at the Center for Advanced Studies at Stanford University in the US.

Prof Jansen’s rating follows P-rating
Prof Jansen’s rating also adds to the recent P-rating awarded to Dr Daniel Spence, a postdoctoral Research Fellow at the International Studies Group. In receiving the rating, the UFS became the only university in South Africa with a P-rated researcher in History.

P-ratings are given to young researchers, usually under the age of 35, who have the potential to become leaders in their field. Researchers in this group are recognised by all, or the overwhelming majority of, reviewers, as having demonstrated the potential to become future international leaders. 

“Obtaining another A-rating is indicative of the university’s drive to enhance its research profile – nationally as well as internationally. I am thankful to our scholars for their commitment to the rating process and look forward to receive the results of this year’s ratings,” said Prof Corli Witthuhn, Vice-Rector: Research at the UFS.   

Total number of researchers increased
The UFS has also upped the ante with regards to its total number of NRF-rated researchers during the latest rating and evaluation with an increase from 127 in 2015 to 149 rated researchers in 2016.

In 2015, Prof Maxim Finkelstein from the Department of Mathematical Statistics and Actuarial Science, and Prof Melanie Walker, Senior Research Professor and Director of the Centre for Research on Higher Education and Development, were given A-ratings.

Prof Finkelstein’s rating then made him the only A-rated researcher in ‘Probability and Statistics’ regarding Mathematical Sciences in the country. Prof Walker was evaluated and graded in the division for Research, Innovation Support and Advancement.

According to the NRF, A-rated researchers are “unequivocally recognised by their peers as leading international scholars in their field for the high quality and impact of their recent research outputs”.

 

The rating of individuals is based primarily on the quality and impact of their research over the past eight years.
