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.”

The UFS produces some of the finest teachers in the country
2015-03-02

 

The quest for producing well-grounded, excellent and prolific teachers at the UFS is bearing fruit. Numerous accolades have over the years been bestowed on some of the UFS Qwaqwa Campus's finest graduates.

"For us as the faculty, it is gratifying and rewarding to learn about the achievements of our students. These achievements do not only validate our efforts, but inspire us as well,” says Dr Dipane Hlalele, Assistant Dean in the Faculty of Education at the UFS.

Dr Hlalele also revealed that, in the recent past, the faculty at the Qwaqwa Campus has experienced an increase in the enrolment figures for teacher training.

"Numbers in our initial teacher education programmes grow in leaps and bounds and we produce some of the best teachers in the country. We are proud to say that on graduation day, our students receive at least two things, i.e., their qualifications as well as entry into the teaching profession," added Hlalele.

Some of the shining examples that Dr Hlalele referred to, are Tebello Tshabalala (English), Mthobisi Khumalo (Mathematics), Thabo Mohapi (Physical Sciences), Lehlohonolo Khanye (Accounting) and Yvonne Tsotetsi (Business Studies). All of these are educators at Lekgulo Senior Secondary School in Qwaqwa and have each produced a 100% pass rate in the 2014 examinations.

There is also Nape Motloung, whose excellent Mathematics results at Botshabelo's Lefikeng High School have placed him as the Top Mathematics Educator in the Free State. Motloung's consistent excellent results have also placed his school in the Top 10 of the Best Performing Schools in Mathematics. This has also won his school R100 000 from the Free State Department of Education.

At yet another Qwaqwa school, Sekgutlong Secondary, Malefetsane Mokomotoane's Mathematics results over the years have earned him a runner-up prize in the category Excellence in Teaching Mathematics at the 2014 National Teachers Awards hosted by Minister Angie Motshekga.

"I am proud to have had 98% of my learners pass Mathematics, with 10 distinctions," said an elated Mokomotoane, who has just been appointed Principal of Selelekela Secondary School in Qwaqwa.

"Having achieved an average of 59%, my highest ever, has taught me and my learners that through hard work, anything is possible," added Mokomotoane.
