The University of the Free State (UFS) is gearing up to be a leading academic institution in astronomical research. The institution successfully mounted a spectrograph with a polarimeter to the Boyden Observatory 1,5-m telescope that will provide scientists with visual access to both the Northern and Southern Hemispheres.

The instrument, which can be accessed from Boyden, an astronomical research observatory and science education centre a few kilometres outside Bloemfontein, will allow researchers such as the Astrophysics Group at the UFS to do simultaneous polarimetry and spectroscopy of astronomical sources. This is vital for the research they are working on.

Mounting the spectrograph to the telescope and installing the polarimeter completed the upgrade of the 1,5-m telescope and is a leap forward for the astrophysics group at the UFS. The upgraded telescope with the spectropolarimeter, with a valued cost of R1.5 million, will also provide unique opportunities for collaborative research between the Astrophysics Groups at the UFS and researchers from the Appalachian State University (ASU). This adds greatly to the astrophysics research capacity at the university.

Prof Richard Gray, who 2019 started with the development of the astronomical spectrograph for the UFS Department of Physics, is a world-renowned expert in stellar spectroscopy, from the Department of Physics and Astronomy at ASU in North Carolina in the US. He was mainly responsible for the development and building of the instrument.

Prof Pieter Meintjes, Senior Professor from the UFS Department of Physics, describes the moment that installation was completed as a feeling of enormous relief. “It took many hours of hard work, planning and testing to marry the 90-year 1,5-m telescope with the new sophisticated instrument,” he says.

Adding value to graduate programme

Besides the development and installation of the spectrograph, Prof Gray also designed and built a polarimeter which can be integrated with the spectrograph. When placed inside the spectrograph, this piece of equipment transforms the spectrograph into a spectropolarimeter, giving it additional functionality. “This allows us, for example, to detect and analyse polarised light. It enables us to study the effect of magnetic fields in astronomical sources which introduce various polarisation signatures that can be detected with the polarimeter,” explains Prof Gray.

“I am fascinated by the polarimetric capabilities that we never had before. It is a great step forward,” remarks Prof Meintjes.

“The Department of Electronics and Instrumentation at the UFS played an enormous role in the building of several components of the instrument that Prof Gray designed, as well as getting the 1.5-m telescope research ready so that the completed instrument could be mounted to the telescope”, says Prof Meintjes

He envisages that the research instrument will be ready for research purposes by March this year. Up till then researchers, graduates, and third-year students will have the opportunity to spend time on the spectrograph to familiarise themselves with it.

“Once installation is finalised, the UFS will be the only academic institution in South Africa with access to a 1.5-m telescope paired with a spectrograph. This gives us an edge in terms of our astrophysics programme and the training we provide our students. It also adds so much value to our graduate programme,” he says.

New instrument provides much flexibility

The spectrograph offers Prof Meintjes many possibilities for his research, and he is eager to put the instrument to use. To study binary systems as well as the jets of Active Galactic Nuclei (AGN), you need a spectrograph, preferably with polarimetric capabilities. It can also be applied to finding elements at the surface levels of stars so that their chemical composition can be determined.

“In the past, we needed to send our researchers to Sutherland and they were never guaranteed clear skies. Having this facility gives us so much flexibility,” he says.

Prof Brian van Soelen from the Department of Physics will be a key user of the spectrograph for his research. He is also playing an important role in terms of postgraduate training and research where the spectrograph is applied.

The polarimeter converts the spectrograph to a spectropolarimeter. This instrument, which is mounted on a telescope (in the case of the UFS, it is mounted on the Boyden 1,5-m telescope) enables the user to detect whether radiation from astronomical objects are polarised and to analyse the level of polarisation of the light. Scientists can then, for instance, study the effect of magnetic fields in astronomical sources, which introduce various polarisation signatures (typically with a characteristic level of polarisation).

You have the knowledge, which is a big resource, and should use it to the benefit of South Africa. This was the overwhelming message to graduates obtaining their master’s and doctoral degrees at the University of the Free State (UFS).

Their responsibility was emphasised by the likes of Justice Mahube Molemela during the ceremonies in the Callie Human Centre at the Bloemfontein Campus on 26 June 2017. Justice Molemela, Judge President of the Free State Division of the High Court and Acting Justice of the Supreme Court of South Africa, was the guest speaker at the morning and afternoon ceremonies.

The UFS conferred 388 master’s and 72 doctoral degrees on the final day of its mid-year graduation ceremonies, which was the biggest set of ceremonies in the university’s history. The doctorates came from the Faculty of Natural and Agricultural Sciences (30), Faculty of the Humanities (15), Faculty of Economic and Management Sciences (9), Faculty of Education (8), Faculty of Health Sciences (5), and Faculty of Theology (5). A total of 5 258 degrees were conferred over six days from 19 to 26 June 2017.

Future dependant on youth
Justice Molemela said the master’s and doctoral graduates have the skills to make a difference. “The future of a nation is largely dependent on its youth playing a meaningful role in creating a strong economy, culminating in a good standard of living for everyone.”

She said they should plough back into their communities and give opportunities to others. “I am certain that if each one of you thinks innovatively in your respective fields, you will find solutions which will eradicate poverty, improve service delivery, and hence our education will advance gender equity, and promote public participation.”

Dr Khotso Mokhele, UFS Chancellor, said these graduates have every reason to hold their heads high, their shoulders square, and walk with a bit of an attitude, as they have distinguished themselves.

Generation of new knowledge
According to Prof Francis Petersen, Rector and Vice-Chancellor, the UFS strives to be a university that is research led. “For me, one of the important aspects about universities which set them apart from other training and vocational institutions is the generation of new knowledge,” he said at a lunch function for PhD graduates on 26 June 2017. He feels it is critically important for them to make a contribution to the country.

Dipiloane Phutsisi, Principal and Chief Executive Officer of the Motheo TVET College in the Free State, also emphasised this. Phutsisi was the guest speaker on 23 June 2017. “Your courage and eagerness to face the future and tell the truth in the midst of this confusion, is highly desired by South Africans.”

Justice Ian van der Merwe, Judge of Appeal at the Supreme Court of Appeal and former Chair of the UFS Council, was the guest speaker at the ceremonies on 22 June 2017. He encouraged graduates from a chapter in the book War and Peace by Leo Tolstoy.

“There is no greatness where there is not simplicity, goodness, and truth (according to Tolstoy). Or maybe more modernly translated: There is no greatness where simplicity, goodness, and truth are absent.”
