Stable atmospheric environments and near perfect weather conditions were the main reasons for the establishment of the Boyden Observatory a few kilometres outside Bloemfontein. This astronomical research observatory and science education centre is managed by the Department of Physics at the University of the Free State (UFS).

With the newly acquired astronomical spectrograph for the Boyden Observatory 1,5-m telescope, scientists will be able to gain visual access to both the Northern and Southern Hemisphere skies.

Collaboration with expert in stellar spectroscopy 

The spectrograph, mainly developed and built by Dr Richard Gray, will be used collaboratively for astronomical research by the UFS and the Appalachian State University (ASU) in North Carolina, where Dr Gray is based. 

Dr Gray is a world-renowned expert in stellar spectroscopy and leading author of one of the most influential textbooks on stellar spectroscopy, Stellar Spectral Classification, with co-author Christopher J Corbally.

Dr Gray recently received a Fulbright Scholarship from the Fulbright Foundation to spend a full year in the UFS Department of Physics, where he will lecture several Astronomy classes and do research in collaboration with personnel of the UFS Astrophysics Research Group. He will also lead the assembly of the instrument over the next few weeks, working with personnel and students in the Department of Physics as well as the UFS Instrumentation Division.

According to Prof Pieter Meintjes, Senior Professor from the UFS Department of Physics, some components of the instrument have been developed and constructed by the university’s Instrumentation Division, with key components purchased from funding by the Directorate: Research Development at the UFS.

Unique capability in infrastructure 

“The availability of a sophisticated instrument of this nature on the 1,5-m telescope will place the UFS Astrophysics Group in an elite bracket in terms of the available infrastructure for astronomical research,” said Prof Meintjes.

He explained: “The combined polarimetric-spectroscopic capability in one single instrument is unique. Combined with the fact that it is hosted on a research instrument that is utilised and maintained exclusively by the UFS Astronomy Group in the Department of Physics, gives this group a competitive edge in relation to most international astronomy groups.” 

The instrument is valued at close to R1,5 million.

According to Prof Meintjes, the instrument will be mounted at the backend of the UFS Boyden 1,5-m telescope and will allow them to do simultaneous polarimetry and spectroscopy of astronomical sources. “This is vital for the research we are working on,” he said.

International collaboration and student development

The instrument also brings with it the possibility of forging international collaborations for research as well as student development. “This can advance the stature of the UFS as an internationally respected research-led tertiary institution,” said Prof Meintjes. 

The possibility of making the UFS Boyden 1,5-m telescope completely remote-controlled, is being investigated. “This will serve the observational needs of researchers from both the UFS and the ASU, with researchers at ASU able to access the telescope for their own in-house research programmes. The availability of such an instrument on the UFS 1,5-m telescope also opens up the possibility to accommodate visiting researchers from ASU or elsewhere in the world at Boyden,” said Prof Meintjes.

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.
