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. Pictured here, are from the bottom, Teboho Rakotsoana and Simon Rakotsoana from the UFS; Emilio J Garcia from the Institute of Astrophysics of Andalusia; Prof Pieter Meintjes; and Prof Antonio M Carrillo from UCD.

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.”

Sarah, our own champion

Sarah Shannon at the Paralympic Games in Beijing

 

Sarah Shannon, a second-year student in the Postgraduate Certificate in Education, has been involved in disability sport on national level for the past 12 years. Sarah has cerebral palsy.

In 1996 she participated at the South African National Championships for the physically disabled for the first time, entering for several sporting codes and winning five gold medals. In swimming she participates in the S3 class together with other swimmers that have comparable abilities to hers.

In 1997 she decided to focus on swimming competitively. She participated in her first national championships for swimming that year. After that (1998) she represented South Africa on international level at the International Paralympic Committee’s (IPC) Swimming World Championships in New Zealand where she ended 4th in the 50m backstroke and 7th in both the 50m and 100m freestyle in her class.

In 1999 she represented South Africa in Johannesburg at the 7th All Africa Games and won a silver medal for the 50m freestyle and a bronze medal for the 100m freestyle.

In 2000 she was part of the South African team at the Sydney Paralympic Games where she reached the finals and finished 7th in the 50m backstroke and 8th in the 50m freestyle. Northern-KwaZulu-Natal also awarded her the Junior Sportswoman of the Year award in 2001. In 2002 she participated at the South African Senior National swimming championships for KwaZulu-Natal in the multi-disability category.

In 2005 she completed the Midmar Mile. She also represented South Africa at the world championships for athletes with cerebral palsy in Boston in the United States of America. She won two gold medals for respectively the 50m freestyle and the 50m backstroke and two silver medals in the 100m and 200m freestyle. She was also nominated to represent South Africa as athlete’s representative on the world committee of CPISRA (Cerebral Palsy International Sports and Recreation Association). In this year Sarah also received the KwaZulu-Natal Premier’s Sportswoman with a disability award of the year.

In 2006 she qualified for the IPC world championships but could not attend.

In 2007 she represented South Africa once more at the Visa Paralympic World Cup in Manchester in the United Kingdom where she broke the South African record in the 50m backstroke, finishing 7th in the 50m freestyle and 6th in the 50m backstroke.

She was also part of the very successful Team South Africa to the Paralympic Games in Beijing. She reached the finals in both the 50m backstroke and 50m freestyle. She finished 7th in the 50m freestyle and 6th in the 50m backstroke in personal best times for both events. She has been participating in the able bodied South African National Swimming Championships since 2002. She is currently ranked 2nd in the world for short course items and 11th for the long course items. She is truly our best swimmer in the S3 class.
