Prof Pearl Sithole acknowledged the role played by the Afromontane Research Unit in securing mountain-to-mountain research funding from the US Embassy and Consulates in SA.

“This launch is an opportunity to reflect on the strategic significance of the partnership between our two universities and the long-standing relationship that academics at the two institutions have enjoyed.” 

These were the words of appreciation from the University of the Free State Vice-Rector: Research, Innovation and Internationalisation, Prof Corli Witthuhn, during the virtual launch of the Mountain-to-Mountain collaboration project between the University of the Free State and the Appalachian State University in the United States held on 10 November 2020. The R8 million project is funded by the US Embassy and Consulates in South Africa and will run over two academic years.

Prof Witthuhn also stated that the project would further strengthen the UFS strategy for internationalisation. “This collaboration has grown organically in the last decade to become one of the UFS flagships in international collaborations. With the support of this grant from the US Embassy and Consulates in South Africa, this long-standing and sustainable collaboration will be further strengthened,” she added.

New master’s programmes

In providing context to the Qwaqwa Campus’ research footprint, Campus Vice-Principal: Academic and Research, Prof Pearl Sithole, acknowledged the role played by the Afromontane Research Unit (ARU) under the leadership of its Director, Dr Ralph Clark, as well as all the faculties.

“In the Humanities, a lot is coming regarding the socio-ecosystems of the mountains. And in Education and Economic and Management Sciences, the scholarship of teaching and learning is promoted through blended skills, especially during this time of the pandemic. In the Natural and Agricultural Sciences, climate monitoring is one of the projects that has brought vibrancy to our campus,” she said.

Appalachian State University’s Associate Vice-Chancellor for International Education and Development, Prof Jesse Lutabingwa, mentioned that the collaboration would, among others, develop and offer a multi-disciplinary master’s degree in Mountain Studies on the Qwaqwa Campus, which will initially enrol seven to ten students. “In the subsequent years, we plan to increase this number to 15-20 students. We will also develop and offer a Community Development master’s degree with 10-12 students and up to 25 in subsequent years.”

Black women academics

Prof Lutabingwa, who is also the Project Director, revealed that doctoral students who are currently part of the University Staff Doctoral Project (USDP), will conduct at least three research projects focusing on social entrepreneurship, substance abuse, and rural transport monitoring in the Maloti-Drakensberg Mountains. “Also key to this collaboration is the leadership mentorship programme for black women academics who will at the end of the project produce three to five research papers,” Prof Lutabingwa added.

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.
