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 finances are fundamentally sound
2007-12-01

The finances of the University of the Free State (UFS) remain fundamentally sound and a higher than expected surplus of about R26 million was achieved in the 2007 budget.

This announcement was made last week during the last meeting of the UFS Council by Prof. Frederick Fourie, Rector and Vice-Chancellor.

“Up to now, we could finance the considerable investments in the infrastructure from discretionary funds, in spite of the fact that Council granted us permission during 2005/06 to take up a loan of R50 million for this purpose,” said Prof. Fourie.

The higher than expected surplus of about R26 million will be used among other things for the financing of infrastructure in order to further postpone the taking up of a loan.

In support of the drive to reposition the UFS nationally as a university that is successfully integrating excellence and diversity, R5 million will be made available from the surplus for this purpose.

The Council also approved the following allocations for 2008 for the key strategic pillars of a good practice budget for the university:

Information sources: R21,1 million
IT infrastructure: R3,5 million
Replacing expensive equipment: R7,05 million
Research: R18,1 million
Capital expenditure: R28,2 million
Maintenance capital assets: R18,2 million
Reserves: R6,3 million
Personal computers for the computer laboratory: R3,5 million

For the Qwaqwa Campus R2,5 million has been set aside for these issues.

In terms of strategic priorities R8 million was allocated for the academic clusters, R2 million for equitability, diversity and redress and R6 million for equity.

The projected income for 2008 will be R849 million, while the projected expenditure, excluding transfers, will be R694 million.

“Council further approved that discretionary strategic funds be largely voted to the further upgrading of the physical infrastructure, especially the Chemistry Building, the computer laboratory building, examination venues and the Joolkol,” said Prof. Fourie.

According to Prof. Fourie, funds have been reserved for the development of the academic clusters, as well as the continuation and acceleration of the transformation programme of the UFS.

“We have also managed to revise the conditions of employment of contract appointments and align it with the latest labour practices. The phasing in of the fringe benefits of this specific group of staff members will commence in 2008,” said Prof. Fourie.

Given the dependence of the income of the UFS on student numbers, a task team was formed last year to investigate the continued financial sustainability of the UFS. The core of this task team’s recommendations is:

to increase the third income stream by using the academic clusters as the main strategy; and to apply strategies such as the recruitment and extension of the postgraduate and foreign student corps, increase the income from donations and fundraising, etc.
