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.”

Shimlas had the right attitude, says Scholtz

His rugby team had the right attitude to win in difficult conditions in Cape Town.

This is what Hendro Scholtz, Head Coach of Shimlas, had to say after the University of the Free State (UFS) started its Varsity Cup campaign on 8 February 2016 with a victory of 23-17 over Ikeys.

According to him, the UFS had to sweat hard until the end on a windy Green Mile, which has been the downfall of many opponents before. His substitutes also had a great impact.

Troublesome Cape wind

Shimlas have a tough draw this year, and to start in the Mother City was a huge task. Scholtz and his men have only three home matches and will play against most of the major teams in away matches.

“We knew it would be difficult in Cape Town. With the wind blowing as it does, one can't play as you would like to during the rest of the season,” the coach said.

“The guys had a will to win.”

The former Springbok believes that too much cannot be read from the first round results. The Shimlas will play their second match on 15 February 2016 against Tuks in Pretoria.

Replacements with good impact

Only the prop Rudolph Botha, flanker Fiffy Rampeta, and prop Teunis Nieuwoudt, who started against Ikeys, were involved in the 2015 final against Pukke.

Other big Shimla names, such as the prop Ox Nche, hooker Elandré Huggett, prop Conraad van Vuuren, and flanker Daniel Maartens, were sent onto the field in Cape Town after half-time.

“We had a plan with the replacements for the second half. They made a huge difference,” Scholtz said.

Rampeta was named Man of the Match, but it was Maartens and Co who turned the game in their team's favour in the second half.

Matsoele could be out of action for long

The Shimla fullback, Sechaba Matsoele, had to leave the game against Ikeys early because of a knee injury, and could be out of action for some time.

His scrumhalf, Zee Mkhabela, was also injured (by a blow to the head), so Shimlas will have to keep their fingers crossed for his quick recovery.

Scorers:
Shimlas 23 (7): Tries: Arthur Williams, Nardus Erasmus, Mosolwa Mafuma. Conversions: Stephan Janse van Rensburg (2).
Ikeys 17 (0): Tries: Khanyo Ngcukana, Nathan Nel. Conversion: Hilio de Abreu. Penalty: De Abreu.
Other results (home team first): Tuks 15, Pukke 38; UJ 19, Madibaz 12; Maties 40, CUT 0.
