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.”

Examination format at UFS to change
2011-04-22

A new examination format is to be followed from the coming examination in May 2011 at the University of the Free State (UFS). According to this, the additional examination opportunity is to follow on the heels of the main examination.

According to the new format, students who qualify to write examinations will be compelled to write their papers during the first opportunity, and will only be allowed to write an additional examination once their applications for this examination have been approved. Students who qualify for re-assessment and special examinations will automatically be admitted to the additional examination and will therefore be exempt from the application process.
 
According to Dr Saretha Brüssow, Head: Teaching and Learning at the UFS, the Examination Committee requested the investigation of the double examination which applied previously, due to the pressure it caused on the university systems.
 
She said that, besides this release of pressure on systems such as the registration process, the back-to-back semester-based examination system might also lead to a possible improvement of the academic success rate, due to the shorter time span between the first and the second examination opportunities.
 
Students attended classes poorly in the past due to the second examination opportunity, which took place during the following semester after classes had resumed. “In some cases it is specifically the student at risk, who cannot afford to miss classes, who makes use of the second examination opportunity.”
 
Dr. Brüssow said the registration process was also affected by the previous format due to students who wanted to receive their results first before they registered. Other delays which occurred as a result of the second examination opportunity, were the first annual graduation ceremony which took place late in the year, the awarding of bursaries, and the finalisation of residence accommodation. Adding on to this problematic nature is students who occupy residences in the following academic year without a formal application in order to write during the second examination opportunity in January.
 
The new format is applicable to all students, except those in the Faculty of Health. Main and South Campus students can direct enquiries to addexam@ufs.ac.za. Qwaqwa Campus students should email addexam@qwa.ufs.ac.za.  Information on the new examination format is also available on www.ufs.ac.za.
