Prof Francis Petersen
Prof Francis Petersen, UFS Rector and Vice-Chancellor opened the workshop on Monday, 10 February 2020.

Will an enclaved state work in a country like South Africa? How can universities produce graduates who will become engaged citizens, and what is the current status of the ANC and the DA? These were some of the key topics at a workshop on South Africa and Africa: Prevarication at the Precipice, hosted by the Department of Political Studies and Governance at the University of the Free State (UFS). 

The two-day workshop is an annual collaborative discussion platform between the UFS, chaired by Prof Hussein Solomon, the Southern African Centre for Collaboration on Peace and Security, and the Osaka School of International Public Policy

The workshop opened with Prof Francis Petersen, the UFS Rector and Vice-Chancellor who delivered his message from the perspective of higher education. 

He spoke about the importance of universities in South Africa being able to produce graduates who will become active citizens. 

Graduates should fulfill their role in society 

“Universities should be the place where we should educate and engage to let our students and graduates know what society should look like. If we don’t do that transformative thinking among our graduates we are going to perpetuate what society is,” Prof Petersen said. 

“I hope this conference won’t just debate the issues because we already know the answers. I hope this workshop will say what we need to do as active citizens to ensure that we start new building steps. International engagement is also important. As is our engagement with the continent.” 

Helen Zille on the State of South Africa 

Helen Zille, Chairperson of the DA Federal Council presented a talk on the State of South Africa in which she tabled three variables she believes can save the country from the precipice. “There should be three variables which can make a democracy work; a separate state (not a party-ruled state), the rule of law and a culture of accountability,” Zille said. 

Zille tabled the concept of an enclaved state a state which operates independently from party control. “There are increasingly isolated states in SA which are being pushed out of good governance and service delivery. An example of an enclave that functions well is the “justice enclave (Supreme Court of Appeal) in Bloemfontein”. 

She reiterated the importance of active citizenship. However she added that people who are active citizens are usually not the ones elected to office.

The role of active citizenship and the state of the country cannot be discussed in isolation from the state of the ruling ANC and the official opposition, the DA. Prof Dirk Kotze from the Department of Political Studies at Unisa, and Bonolo Selebano, Netwerk 24 political journalist, gave a glimpse into the status of Luthuli House (ANC headquarters in Johannesburg), and the DA. 

“ANC party politics are not unique. They are following a global trend. However, the credibility of the ANC is a big issue,” said Prof Kotze. In the political arena globally, political parties are redefining themselves and it is important for the ANC to figure out where it finds itself. Selebano wasn’t too optimistic about the DA either, saying the party should return to its liberation ideals.

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.
