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.”

UFS Council confirms decision to integrate student residences
2007-09-14

At its quarterly meeting held today (Friday, 14 September 2007) the Council of the University of the Free State (UFS) confirmed the decision taken at its previous meeting that the student residences of the UFS should be racially integrated.

The decision was taken with an overwhelming majority with only one vote against it and will be implemented in January 2008.

The Council tabled and noted the resolution of the Convocation of 11 September 2007 concerning the Council’s initial decision of 8 June 2007 and urged the management to continue to be sensitive, empathetic and inclusive in dealing with the concerns and views of all stakeholders.

The Council also gave all interested parties the assurance that any suggestions that could assist in the successful implementation of its decision would be considered and called once again on all stakeholders to make proposals to the management of the UFS so as to ensure a well-managed process of integration and managing diversity in residences.

In this regard it welcomed the suggestion made by the alumni of the UFS for the introduction of a Diversity Scorecard for residences which would include a multi-dimensional range of indicators and incentives for residences. This could include the diversity profile of a residence, the academic performance of the students in a residence, inter-residence activities and community service projects launched by students.

According to the Rector and Vice-chancellor of the UFS, Prof. Frederick Fourie, the Council hereby also restated the educational motive for the integration of residences, which meant that from an educational point of view, students who had the knowledge and skills to manage diversity would have a distinct advantage in the workplace and in life.

“Today’s decision is a major step forward for the Council and the UFS to achieve a broad consensus around the promotion of diversity at the UFS and in its residences, as the institution has always been committed to giving the best education to students in a diverse and non-racial environment. I would like to call on current students, prospective students, parents, alumni and other stakeholders to make this work in the best interests of the university and its students,” Prof. Fourie said.

He added that the UFS had established several task teams comprising staff and students to implement the Council’s decision of 8 June 2007 and that much work had already been done to identify critical areas and tasks ahead of implementation in January 2008.
