The Faculty of the Humanities webinar series will provide opportunities for future research collaboration.

How does an anthropologist, a linguist, and a health systems researcher collect data during COVID-19 when human interaction is limited? Speaking at the first webinar hosted by the Faculty of the Humanities on Fieldwork in the time of COVID-19, Prof Deborah Posel, Research Professor in Sociology, said, “Lockdown impacted social sciences just as much. For us it was a lockout from people, libraries, and field research.” 

“The benefits (of the webinar) for Humanities research are obvious. Research in the Humanities differs a lot from research in other disciplines such as Natural Sciences; it happens in silos and not as a group focused,” said Prof Heidi Hudson, Dean of the Faculty of the Humanities. This webinar series will provide a platform to engage, but also for inter-departmental and inter-disciplinary research in the faculty. “Using this platform to engage and talk about our shared experiences will help bring researchers together and to reflect on our own experiences,” Prof Hudson said. 

Academics from different departments in the faculty shared how the COVID-19 lockdown affected their research projects. They were Dr Gladys Kigozi, Senior Researcher in the Centre for Health Systems Research and Development (CHSR&D), Dr Kristina Riedel from the Department of Linguistics and Language Practice, and Prof Joy Owen from the Department of Anthropology

Different approaches implemented 

Centre for Health Systems Research and Development
Research in the CHSR&D focuses mainly on in-person research. “COVID-19 has diminished the interaction between researchers and participants, and it threatened the quality of data gathering,” Dr Kigozi said. Field activities were thus suspended for six months, which compromised the timeline of projects.  

The CHSR&D aligned their projects with COVID-19 regulations and had virtual consolidations with the Free State Department of Health, while advertising research through health-care workers and social media.

Department of Linguistics and Language Practice 
For Dr Kristina Riedel, COVID-19 was not the proverbial nail in the coffin of linguistics research. There is great body of spoken, signed or written language that has been transcribed. “Linguists may also study public or private online data or printed texts such as newspapers, social media, and Bible translations,” Dr Riedel said. 

Language documentation usually happens with a researcher interacting with a speaker or group of speakers, which is then recorded in a high-quality, low-noise environment. Just like Anthropology, the best form of understanding data comes from in-person documentation. “We often need to work with people who are not connected to online spaces, such as the elderly and marginalised communities,” Dr Riedel said. Researchers sometimes need to be immersed in the community when recording takes place.

Department of Anthropology 
Prof Joy Owen provided perspective on how Anthropology as a discipline and anthropologists have been impacted by the lack of human interaction, which is what Anthropology is essentially about. “Anthropology, as founded in the early 20th century, is a fully immersive experience. Body, mind, psyche, and spirt were employed to understand the other (people),” Prof Owen said in her opening remarks. The anthropological encounter could thus not be socially and physically distant. 

The continuous shift to virtual interaction is not an ideal practice. “A video call, however initiated, cannot provide access to the daily nuances of life,” Prof Owen said. The video call/interview cannot replace the in-person ‘hanging out.'

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.
