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.”

The Institute for Reconciliation and Social Justice (IRSJ) marked its fifth anniversary with a function on 27 July 2016 in the Reitz Hall of the Centenary Complex on the Bloemfontein Campus of the University of the Free State (UFS). Earlier that day, the Advisory Board of the IRSJ, chaired by Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS, hosted their annual meeting.

A new book was also launched, co-authored by JC van der Merwe, Deputy-Director at the IRSJ and Dionne van Reenen, researcher and PhD candidate at the IRSJ. It is entitled Transformation and Legitimation in Post-apartheid Universities: Reading Discourses from ‘Reitz’. The function featured not only reflections on the IRSJ, but a four-member panel discussion of the book and higher education in 2016.

The IRSJ came into being officially at the UFS in January 2011. Prof André Keet, Director of the IRSJ, said: “With a flexibility and trust not easily found in the higher education sector, the university management gave us the latitude and support to fashion an outfit that responds to social life within and outside the borders of the university, locally and globally.”

The IRSJ has not hesitated to be bold and
courageous in reforming ... traditional policies."

 

Prof Jansen went on to mention three things he finds appealing about the IRSJ: “Thanks to Prof Keet and his team’s vision and understanding of how important it is for students to have a space in which they can learn how to be, learn how to think, and learn how to contribute, the IRSJ has become a place where students can learn about things that they might not learn in the classroom. Second, it created, for the first time, a space where members of the LGBTIQ community could gather in one place. And third, it speaks to the intellectual life of the university, as evidenced by the research and publications produced over the past few years.”

Prof Jansen added: “The IRSJ will only be successful to the extent that we have safe spaces, courageous spaces, in which not only black students talk to themselves, but where black and white students talk together about their difficulties. If you’re entangled, you can’t get out of [that] unless you speak to the other person.”

Prof Michalinos Zembylas of the Open University of Cyprus and member of the Advisory Board, said of the IRSJ: “The works produced by the institute in this short time have been valuable to this community and beyond, because they recognise the complexities of education, ... while pushing the boundaries of how to translate theoretical discussions into practical, everyday conditions. ... For example, the IRSJ has not hesitated to be bold and courageous in reforming some traditional policies in this university—remnants of an ambivalent past that reproduced inequality and disadvantage.

In reflecting on how the IRSJ came into being during her opening remarks, Dr Lis Lange, Vice-Rector: Academic at the UFS, said that it has always been “dedicated to transformation.” She added that it “gathered the energy and creativity of some of our most promising student leaders.” She concluded: “For me, the greatest success of the Institute, besides publications and local and international networks, is the fact that something that started in the margins is being asked today to come closer to the centre, to play a larger role in the structural transformation of the university.”
