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.”

Boys’ roars and ladies’ shouts could be heard from miles away. From this, one could tell that the 2015 first-year’s Swimming Gala was bound to be an exciting one.

While RC Sports members were stressing, the first-years blissfully continued in song and excitement.

One would think that, after a hectic first week of classes, first-years would not have much energy left, but the atmosphere proved that Residence Committees (RCs) had prepared the individuals with rather motivating pep talks before the event. Most male residences put their best foot forward, not holding back on themed attire and additional instruments, while female residences sang and danced to the music provided. Not only were the masses competing to claim that they had the greatest spirit on this night, but they were also waiting to hear the results of the Spirit Cup for the first-years’ Athletics, which was cut short due to heavy rain showers. This simply added to the already intense anticipation of first-years and RC Sports members, as they would receive the results only at the end of the event.

The competition was tough as many of the first-years who competed moved with ease in the water as though it was second nature to them. This year’s gala saw quite a few talented, national swimmers competing, which left those who swam for pride and points intimidated. The excitement of the crowd was heightened as the relay section of the programme approached. This meant that the winners were to be announced soon.

In the ladies’ section, the residences were placed:
• 1st – Marjolein
• 2nd – Wag-‘n-Bietjie
• 3rd – Sonnedou

In the men’s section, the residences were placed:
• 1st – Armentum
• 2nd – Vishuis
• 3rd – Karee

When the time arrived for the announcement of the Spirit Cup winners, many were hopefully clenching their hearts for their name to be roared out. In most people’s opinion, it came as no surprise when Armentum walked away with the Spirit Cup for both the first-years’ Athletics and the Swimming Gala. Furthermore, Armentum’s broader South College community – of which Emily Hobhouse, Marjolein, NJ vd Merwe and Villa Bravado are also part – walked away with the cash prize for the best mascot.

By end of the night, everyone, no matter if they were drenched or dry, experienced the exciting sporting atmosphere at Kovsies that they’ve now become a part of.
