Research group rethinks white societies in Southern Africa

Poor, Precarious, White? Rethinking white societies in Southern Africa, 1930s-1990s is a two-day workshop that was recently convened by the International Studies Group (ISG) with financial support from the office of the Vice-Rector: Academic, on the University of the Free State’s (UFS) Bloemfontein Campus. The event drew together a range of historical research on poor and working-class whites across Southern Africa during the twentieth century, with the goal of uncovering wider histories of race. 

In his welcoming speech, Prof Francis Petersen, Rector and Vice-Chancellor of the UFS, stated that race and its histories have taken on a new and renewed significance, not only in South Africa, but also globally. He said, “I am very proud to see the ISG organising and hosting such a wonderful workshop. It has attracted some of the leading intellectuals in the world on critical studies related to whiteness, and though its focus is on the histories of whites, I am pleased to see that a large number of presentations concern the wider questions of race.”

Mentioning several areas of concern on the world scene, such as policies issuing forth from the Trump government in the USA, violence against new migrants across Europe, as well as challenges of race as exhibited by specific events at the UFS, Prof Petersen said that it is particularly significant for this event to be hosted on one of our campuses. Quoting from Prof Neil Roos’ inaugural lecture held the previous evening, Prof Petersen added, “The histories of race offer the opportunity to rethink the approaches and methodologies of social history, and thus revitalise … the discipline.”

Participants in the workshop came from across Southern Africa, Europe, and the United States, and included leading scholars in the field. The first keynote was by the author of the acclaimed book The Wages of Whiteness: Race and the Making of the American Working Class (published in 1991), Prof David Roediger, who currently serves as Foundation Professor of American Studies and History at the University of Kansas. In his keynote entitled Settlers and Immigrants in Critical Whiteness Studies, Prof Roediger dealt with topics such as Southern Whiteness and Indigeneity in Australia and New Zealand, the relationship between migration and race, as well as how the current focus on the role of the white working class in the election of Donald Trump overlooks the complicity of the middle-class and elite whites who also supported him.

The second keynote address was delivered by Prof Jonathan Hyslop of the Colgate University, on the topic Workers called White and Classes called Poor: The ‘White Working Class’ and ‘Poor Whites’ in Southern Africa, 1910-1994. Prof Hyslop offered a sweeping overview of poor and working-class white experiences in Southern Africa, suggesting attention to comparisons and connections as a way of analysing and understanding the history of the region. 

The workshop was organised by Drs Danelle van Zyl-Hermann and Duncan Money, both Postdoctoral Research Fellows in the ISG, in conjunction with Prof Neil Roos, who is also based in the ISG. The research papers presented at the workshop covered topics as diverse as the experiences of white female civil-service employees in colonial Zimbabwe, French immigrants to the apartheid-era Vanderbijlpark steelworks, and white working-class resistance to state regulation. The papers are to be published in an edited collection which will be included in the Routledge African Studies series.

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.
