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.”

Deaf Awareness Month empowers the hearing impaired
2015-09-21

There are more sign languages in the world than spoken languages. About 600 000 deaf South Africans have the South African Sign Language (SASL) as their first language. There are about 40 schools for the deaf in South Africa. 90% of all deaf children are born to hearing parents. Only about 30% of speech is visible on the lips.

How many of these fundamental facts did you know?

Deaf Awareness Month serves to educate hearing communities about issues that the deaf population face on a daily basis, as well as to honour the history and culture of people who are deaf or hard-of-hearing. For the past 70 years, the University of the Free State (UFS) has dedicated September to hosting events around the topic of hearing impairment.

The theme of ‘With South African Sign Language rights, our children can!’

This year’s theme had learners from Bartimea School for the Deaf and Blind, hearing impaired UFS students, and Prof Jonathan Jansen engaged in a conversation around empowerment at a picnic held on Monday 7 September 2015 at the Red Square on the Bloemfontein Campus.

Through a sign language interpreter, Matshela, a grade 12 learner, explained that he felt empowered by the efforts the university has made to embrace and empower individuals with disabilities. He then revealed his intentions of pursuing Information Technology or Social Work studies at Kovsies.

Clifford Machete, a first-year Administration student at the university, stated how sign language interpreters gave him an ‘I can’ attitude when he first arrived at university.  “As a deaf person, I see that I am able to learn with the help of sign language interpreters. There is accessibility at the university, and I am so proud to be a student here and part of Deaf Awareness Month.”

Susan Lombaard, Lecturer and Acting Chairperson at the Department of South African Sign Language, believes that Deaf Awareness Month is about promoting human dignity.

“We want to show the world that deaf people can do everything, and that their language is as strong and important as any spoken language.”
