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.”

Early diagnosis of hearing loss is important

One of the most common, misunderstood and neglected birth defects in developing countries is hearing loss, which can most severely impair and have a dramatic impact of the quality of life the of the person with hearing loss. 

This is according to Dr Magteld Smith, lecturer in the Department of Otorhinolaryngology at the University of the Free State (UFS). 

“Hearing loss refers to all the different types and levels of hearing loss, from slight to profound hearing loss,” she said. 

Derived from a number of retrospective studies in South Africa, it was found 17 people a day are born with hearing loss. More than 95% of those children are born to hearing parents. This estimate excludes children and adults who lost their hearing after birth. 

According to Dr Smith, hearing loss strikes at the very essence of being human, because it hinders communication with others. To enable people to communicate with those with hearing loss, the university’s Department of South African Sign Language teaches students sign language. This year, the department enrolled 230 students. A number of these students are from the Faculty of Education. These students could from 2017 for the first time choose sign language as a subject.

“Studies have shown that important language skills are learned before the age of three because hearing and learning language are closely tied together. Brain development of the auditory pathways and language cortex is occurring in young children as they respond to auditory and visual language. In families that are part of deaf culture, these parents automatically sign from day one, so the baby is learning visual (sign) language, and the appropriate brain development is occurring.

“However, if a child has an undiagnosed hearing loss and the parents are unaware, the child will not receive the needed language stimulation — and the hoped-for development won’t take place. It is critical to understand that children with hearing loss have their own talents, different levels of intelligence, socioeconomic circumstances and different abilities, just like hearing children. Therefore, one size does not fit all,” Dr Smith said.
