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 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.”

Giraffe research broadcast on National Geographic channel
2016-03-09

Description: Giraffe research  Tags: Giraffe research

A documentary focusing on the latest and most interesting research about giraffes was recently broadcasted on National Geographic. Dr Francois Deacon from the UFS Department of Animal, Wildlife and Grassland Sciences and the team of researchers working with him, were first in the world to equip giraffes with GPS collars, and to conduct research on them.

Research by Dr Francois Deacon, from the UFS Department of Animal, Wildlife and Grassland Sciences, involving the equipping of giraffes with GPS collars, was broadcast this week as part of a documentary (4 March 2016 and subsequent weeks) on National Geographic (Channel 182). The documentary is the first of two on his team's research.

Dr Deacon and the team of researchers working with him were the first in the world to equip giraffes with GPS collars, and to conduct research on this initiative. The group of researchers can now follow the animals night and day by means of the GPS collars, while monitoring their movements from a distance on a computer screen and seeing the world from a giraffe's perspective.

“The documentary focuses on the latest and interesting information about our research in different countries,” Dr Deacon said. Besides their local research on giraffes, he and his team also assist in other projects and research in Namibia, Botswana, Zambia, Kenya, the Democratic Republic of the Congo, and Uganda.

“There is much to learn from the documentary,” Dr Deacon said. Interesting facts from their research include herd interactions by individuals towards each other, bulls versus bulls, and cows versus calves. In the documentary, the viewer can also learn how giraffes use thermoregulation, their tongues, and roaming areas and distances; peculiar behaviour such as feeding on bones and soil; bulls fighting; how and when giraffes drink water; and the conservation and management of giraffes.
 
Focus is also placed on the manner in which the latest research plays a role in the better understanding of the animals.
 
According to Dr Deacon, this is the first documentary to focus on giraffe research on such a large scale. Marco Polo Films from Terra Mater are contracted by National Geographic to produce nature films – this was the hundredth nature film produced by them.
 
“There has never before been such a production about giraffes. It also attracted huge interest and reaction overseas, which will provide great exposure for our research and for the UFS.
 
“We believe that the media involvement will provide much more exposure to giraffes, which is a good thing, since they are facing extinction in Africa. The exposure can, in itself, lead to new research and has already started attracting international students to the UFS,” Dr Deacon said.
 
The second documentary will follow later this year. Iniosante, a film team from Texas, USA, is producing this film, which focuses on the extinction of giraffes. It is the same team responsible for the production Last of the Longnecks.
