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 knowledge gained with research made possible by the robotic telescope will lead to a more complete and better understanding of the universe. – Prof Peter Meintjes

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.”

National Arts Council opens doors for students in Drama and Theatre Arts

Four postgraduate students from the University of the
Free State received bursaries from the National Arts
Council this year. They are, from the left: Gerrit Fourie,

Thanks to bursaries from the National Arts Council (NAC), many students are finding it easier to study Drama and Theatre Arts, the discipline is able to offer more job opportunities, and it provides an opportunity to those who probably would never have had the chance. This is according to Prof Nico Luwes, Head of the Department of Drama and Theatre Arts at the University of the Free State (UFS).

This year, several students from the UFS, including 12 undergraduates and four postgraduates, are again beneficiaries of NAC bursaries to the value of roughly R206 000 – about R150 000 of which will be used for undergraduate studies and R56 000 for postgraduate studies. The UFS was awarded the same amount for undergraduate students in the previous year, but didn’t then receive NAC bursaries for postgraduate studies.

Good relationship with NAC over many years
The UFS has received NAC bursaries since 2005, and Prof Luwes says the university’s good relationship with the council runs over many years. “They are very happy with the feedback on our students’ achievements,” he says.

“Although Dramatic Arts is a matric subject, the provincial department of education does not support students with education bursaries for this subject. With bursaries from the National Arts Council, students can thus study to become theatre artists, and work as teachers for the Dramatic Arts in schools.”

Alumni stand out in entertainment industry
Prof Luwes says his department provides students the opportunity to do performances and practical exams in English, Afrikaans, and Sesotho. This is done to give all students an equal opportunity to excel. “In addition, several of our alumni have achieved success in the entertainment industry, and our staff members often feature in professional performances at arts festivals.”

Undergraduate students who were awarded NAC bursaries:
•    Jolene Swartz
•    Boitumelo Mohutsioa
•    René Lombard
•    Mandisa Wiso
•    Thapelo Mabona
•    Charlize Oberholster
•    Thembisile Baai
•    Naledi Maolusi
•    Mbuyiselo Nqodi
•    Vuyiswa Mxasa
•    Deandi Scholtz
