New robotic telescope gives UFS edge over international astronomy groups

13 May 2022 | Story Leonie Bolleurs | Photo Leonie Bolleurs

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.”

Prof. Letticia Moja a winner in her category

Prof. Moja a finalist in award
'Every member of staff is important to me'

Michelle Cahill - Bloemnuus

IF you are in need of a dose of inspiration, try and get an appointment with Prof. Letticia Moja, the Dean of the Faculty of Health Science at the University of the Free State. It will not be easy as she has an extremely tight schedule, over and above being a finalist in the 2004 Shoprite/Checkers Woman of the Year competition.

Although not a born and bred Free Stater, this dynamic woman has come to love the Free State. "Once you get past the mindset of a small town and all the negatives surrounding it, it is an absolutely wonderful experience," Moja said.

Moja was born in Pretoria and grew up in Garankuwa as the second eldest of five children. "That was nothing special. I was not the eldest and I wasn't the youngest," she quipped. She had two younger brothers, one of whom died in a car accident and then two sisters.

She went to school in Pretoria and her first contact with the Free State was when she wrote her matric at Moroka High School in Thaba Nchu. "That was one of the best schools for us at that time," she says. After completing matric, she went on to study medicine in KwaZulu-Natal.

In 1982 she returned "home" and completed her internship at the Garankuwa Hospital. Hereafter she specialised in gynaecological obstetrics at Medunsa.

She became the head of the gynaecological obstetrics unit and later opened a branch in Pietersburg.

"This was just about the most heart-rending time of my life. You saw people travelling for up to three days just to see a doctor," she says. "Here we really interacted with the community."

In 2001 she was invited by the University of the Free State to apply for the job of vice-dean of the Faculty of Health Science. "I wasn't too keen," she says, "but they kept on calling to find out if I had applied or not," she says with a smile. "Eventually I gave in and was appointed."

She thought she would work a couple of years under Prof. Kerneels Nel, then the dean of the faculty. "Unfortunately that was not to be. I had hoped that I could learn from him," Moja says.

Prof. Nel died of a heart attack in 2003 after which Moja deputised for him before being appointed as dean.

"This brought along a whole newset of challenges," she says, "Now I have to work out budgets and I need to know what human resources are," she jokes. This has prompted her to take up her studies again and she is currently doing her MBA.

"It has certainly been a challenge to go into management and without my support structure I most certainly wouldn't have been able to do it," Moja says.

Moja is actively involved in her church and serves on various committees including the Health Professional Council where she is acting president of the Medical and Dental Board and the Provincial Aids Council.

To her no job is menial. She recalls when she used to have "high tea" with her staff in Gauteng and Limpopo. "One of the cleaning ladies used to think her job was menial. That is just not so. No hospital can do without even the lowest position. Imagine stepping over rubbish while you're trying to catch a baby. To me everybody is important no matter what you do. "

Moja's eldest daughter is studying for her B.Accounting degree at Wits . Her youngest daughter is in Gr. 9 at Eunice and she has also brought along her niece, who is in Gr. 8 at Eunice. "You see, we need to be three girls in the house."
She feels honoured to have been nominated by the institution especially as it is traditionally male-dominated. "It is not about me, but about the support structure. Nobody can do it on their own. It is a team effort."
