June Graduation medalist — Recipients of special awards are from left; Elzmarie Oosthuizen, Council Medalist; Jannie de Villiers, Chancellor's Medalist; Dr Khotso Mokhele, UFS Chancellor; Dr Jerry Mofokeng Wa Makhetha, and Dr Barnard Fanaroff, both honorary doctorate recipients.

The UFS presented a number of special awards during the graduation ceremonies on its Bloemfontein Campus on 27 and 28 June 2019.

Jannie de Villiers earns UFS Chancellor’s Medal

Chief Executive Officer of Grain SA and recipient of the 2019 Chancellor’s Medal, Jannie de Villiers, is a renowned leader in the agricultural and food sectors, nationwide and globally. He started his career as an economist for the South African Department of Agriculture in 1985, and dedicated more than 30 years of his knowledge, skills, and leadership to the agricultural sector, specifically in grain-industry development.
Mr De Villiers is commended for a number of initiatives he has implemented to enrich people’s lives throughout his career. One of his many admirable achievements is equipping upcoming farmers with the necessary knowledge and practical skills to advance crops and establishing a sustainable livelihood for South African citizens in the process.

UFS Council honours Elzmarie Oosthuizen

Council Medal recipient, Elzmarie Oosthuizen, is the Director: Centre for Excellence in Teaching and Learning in the UFS Faculty of Natural and Agricultural Sciences (NAS).
Oosthuizen’s experience and leadership in foundation and bridging programmes are exceptional. She has successfully initiated a programme to promote teaching and learning in Mathematics, Natural Sciences, Economics, and Agricultural subjects. Due to her active involvement in managing foundational and bridging programmes for students who do not meet the minimum requirements for mainstream higher-education degrees in NAS, the pass rate of the BSc bridging programme has increased from 34% to 83%.

“This award inspires me to sustain my efforts and find extraordinary solutions for the challenging and complex scenarios that we are facing in higher education,” said Ms Oosthuizen.

UFS June graduation Dean’s Medal recipients

Michelle Nöthling (Master of Arts in Africa Studies) in the Faculty of the Humanities and Megan Braithwaite (Master of Arts in Theology with specialisation in Bible Translation) in the Faculty of Theology and Religion were awarded Dean’s Medals on the morning of 28 June 2019. The Faculty of Education also honoured Deborah Lynn Fair, who achieved the best results for her master’s degree in Education with specialisation in Curriculum Studies, with a Dean’s Medal.

On the afternoon of 28 June, Teboho Mooko (Master of Medical Science with specialisation in Pharmacology) received the Dean’s Medal in the Faculty of Health Sciences. Tshanduko Mutandanyi (Master of Science majoring in Geohydrology) received the Dean’s Medal in the Faculty of Natural and Agricultural Sciences, as well as the Senate Medal for the best overall results in both under- and postgraduate qualifications in all the UFS faculties.

Dr Khotso Mokhele hosts Chancellor’s Dinner

Later that evening, the Chancellor of the UFS, Dr Khotso Mokhele, hosted the Chancellor’s Dinner in the Centenary Complex on the UFS Bloemfontein Campus, paying tribute to the outstanding achievements of the recipients of UFS honorary doctorates, Council and Chancellor’s medals, and doctorates.

Among the honoured guests were the two honorary doctorate recipients, Dr Jerry Mofokeng wa Makhetha – world-renowned, respected television and theatre actor (DLitt Honoris Causa – Faculty of the Humanities), and Dr Bernie Fanaroff (DSc Honoris Causa – Faculty of Natural and Agricultural Sciences), who is the Co-chair of the BRICS (Brazil, Russia, India, China and South Africa) Working Group on Information and Communication Technologies and High-Performance Computing, and member of the Advisory Committee of the Breakthrough Listen project; Mr Jannie de Villiers; Ms Elzmarie Oosthuizen; the Rector and Vice-Chancellor of the UFS, Prof Francis Petersen; and Mr Willem Louw, Chairperson of the UFS Council.

Guests also enjoyed a musical performance by the Graduation Instrumental Ensemble under the direction of Anton Esterhuyse, accompanied by the vocal ensemble of Thabo Hlongwane, Jacobus Silwer, and Mario Lategan.

In August 2017, the Boyden Observatory in Bloemfontein played a major role in obtaining optical observations of one of the biggest discoveries ever made in astrophysics: the detection of an electromagnetic counterpart to a gravitational wave event.

An article reporting on this discovery will appear in the prestigious science journal, Nature, in October 2017. Co-authors of the article, Dr Brian van Soelen and Hélène Szegedi, are from the Department of Physics at the University of the Free State (UFS). Both Dr Van Soelen and Szegedi are researching multi-wavelength astronomy.

Discovery is the beginning of a new epoch in astronomy

Dr van Soelen said: “These observations and this discovery are the beginning of a new epoch in astronomy. We are now able to not only undertake multi-wavelength observations over the whole electromagnetic spectrum (radio up to gamma-rays) but have now been able to observe the same source in both electromagnetic and gravitational waves.”

Until recently it was only possible to observe the universe using light obtained from astronomical sources. This all changed in February 2016 when LIGO (Laser Interferometer Gravitational-Wave Observatory) stated that for the first time they had detected gravitational waves on 14 September 2015 from the merger of two black holes. Since then, LIGO has announced the detection of two more such mergers. A fourth was just reported (27 September 2017), which was the first detected by both LIGO and Virgo. However, despite the huge amount of energy released in these processes, none of this is detectable as radiation in any part of the electromagnetic spectrum. Since the first LIGO detection astronomers have been searching for possible electromagnetic counterparts to gravitational wave detections.

Large international collaboration of astronomers rushed to observe source

On 17 August 2017 LIGO and Virgo detected the first ever gravitational waves resulting from the merger of two neutron stars. Neutron star mergers produce massive explosions called kilonovae which will produce a specific electromagnetic signature. After the detection of the gravitational wave, telescopes around the world started searching for the optical counterpart, and it was discovered to be located in an elliptical galaxy, NGC4993, 130 million light years away. A large international collaboration of astronomers, including Dr Van Soelen and Szegedi, rushed to observe this source.

At the Boyden Observatory, Dr Van Soelen and Szegedi used the Boyden 1.5-m optical telescope to observe the source in the early evening, from 18 to 21 August. The observations obtained at Boyden Observatory, combined with observations from telescopes in Chile and Hawaii, confirmed that this was the first-ever detection of an electromagnetic counterpart to a gravitational wave event. Combined with the detection of gamma-rays with the Fermi-LAT telescope, this also confirms that neutron star mergers are responsible for short gamma-ray bursts.

The results from these optical observations are reported in A kilonova as the electromagnetic counterpart to a gravitational-wave source published in Nature in October 2017.

“Our paper is one of a few that will be submitted by different groups that will report on this discovery, including a large LIGO-Virgo paper summarising all observations. The main results from our paper were obtained through the New Technology Telescope, the GROND system, and the Pan-STARRS system. The Boyden observations helped to obtain extra observations during the first 72 hours which showed that the light of the source decreased much quicker than was expected for supernova, classifying this source as a kilonova,” Dr Van Soelen said.
