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.”

First Rand Foundation contributes funding towards students with disabilities

Bursary funding for eight students with disabilities at the University of the Free State was recently approved by the First Rand Foundation. The grant of R2 497 440 will be paid over three years: R800 000 (2016/17), R824 000 (2017/18), and R873 440 (2018/19).

This grant from the First Rand Tertiary Education Fund is a result of the negotiations between the UFS Office for Institutional Advancement and the First Rand Foundation (FRF).

Qualifying students with disabilities will be encouraged to apply for bursaries according to criteria and requirements set by the First Rand Foundation. The selection process will be handled by a panel from the UFS. The Centre for Universal Access and Disability Support (CUADS) at the UFS will be instrumental in the process of identifying students with disabilities who meet the criteria and requirements for funding.

CUADS already have a system in place to support students with disabilities in their studies and during exams. Students also have access to specialised exam and test venues for alternative test and exam procedures, as well as computer facilities.

Specialised support services include an amanuensis (scribe) service during tests and exams, accommodating extra time, individual tutor sessions provided in collaboration with the Centre for Teaching and Learning, South African Sign Language interpreter coordination, provision of accessible study material, and individual disability support.

 

“The centre aims to ensure that the university increasingly becomes a universally accessible environment that is welcoming and accepting to people with diverse abilities.”

According to Martie Miranda, Head of CUADS, the centre aims to ensure that the university increasingly becomes a universally accessible environment that is welcoming and accepting to people with diverse abilities. “Therefore disability awareness training and advocacy within the UFS, and specifically among staff members, is one of our priorities,” she said.

According to Thandeka Rantsi from the FRF, the company will furthermore support students in CUADS with regards to the needs ensuing from the #feesmustfall protests. “Exactly R34 000 was approved by the FRF for 14 students towards residence and meal expenses, as well as scribe and reader assistance during additional assessments,” she said.
