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.”

Another opportunity to take part in Success Week
2010-07-08

Student Development and Success (SDS) at the University of the Free State (UFS) is focused on helping students succeed as lifelong learners. To accomplish this, SDS has designed Success Week to provide students with the necessary skills and information to help them succeed in their studies.

The success of the first-semester orientation programme has led to the decision of hosting a Get.Success@UFS 2010: Reloaded programme from 19 to 29 July 2010.

Students who previously attended the programme thoroughly enjoyed the programme and learnt a lot from it. It also became clear that they needed more support. The aim of the Reloaded programme is to enhance students’ thinking processes regarding their personal as well as career development. It is open to all students. The focus of the presentations will not only be on helping students to make a success of their studies but also to provide those students who are completing their studies with useful knowledge and skills to plan for their career pathways.

The Get.Success@UFS 2010: Reloaded programme starts on Monday 19 July with a launch where Prof. Jonathan Jansen, Rector and Vice-Chancellor of the UFS, will address students and motivate them once again for the second half of the 2010 academic year. Thereafter the UFS staff will compete against the SRC in the 5-on-a-side soccer tournament that will take place at Pellies Park. Members of Bloemfontein Celtic will also be present. Students can spend the day participating in the mini soccer tournament or just come and support their teams.
This is an excellent opportunity for students to make new friends and spend the day relaxing before the start of the second academic term. There will be prizes for the winning teams as well as for the best war cry and the most spirited team and fan base. There will also be funky give-aways for the spectators.

For the rest of the week there will be three interactive sessions which students can attend to help equip themselves with the necessary skills to succeed in their studies and future endeavours. The sessions include: Game Plan for Success, How to Build your Fortune, CV Writing, and Job Hunting.
Blackboard training will be hosted during the two weeks to show students how to effectively use this medium in their studies. There will be two opportunities for students to visit and be taken on a tour through the library to learn about the services offered.
