The 2020 programme around the 16 Days of Activism against Gender-Based Violence will be novel in that it will be run online. “For each person to register and log into the various programmes is a small step. But each such step makes a big difference by saying that the lives of survivors matter and by underscoring that gender-based violence will not be tolerated at the UFS,” says Prof Colin Chasi, Director of the Unit for Institutional Change and Social Justice (UICSJ) at the UFS.

Women and girl children have experienced increased violence in the time of the COVID-19 lockdown, states the UN Secretary General's report, Shared Responsibility, Global Solidarity: Responding to the socio-economic impacts of COVID-19. In South Africa, there have been reports of a scourge of rape in the post-school education and training sector. At the UFS, these developments have challenged the Gender Equity and Anti-Discrimination Office (GEADO) to come up with innovative online interventions.

In 2019, the University of the Free State (UFS) established the Unit for Institutional Change and Social Justice (formerly known as the Institute for Reconciliation and Social Justice, founded in 2009). The GEADO was launched on 8 April 2019 and was incorporated into the unit to run a cross-functional Sexual Assault Response Team (SART) and to organise programmes that combat gender-based violence and other forms of gender injustice.

“We have been able to offer our services with minimal disruption throughout the year,” says Geraldine Lengau, a Bloemfontein Campus-based GEADO officer.

“Most exciting for us is that we have taken the lockdown as an opportunity to expand the scope of ways in which we engage with students and communities,” notes Chelepe Mocwana, a GEADO officer on the South Campus. “GEADO has offered a number of online webinars and seminars, and the university has made telephonic services available that support, for example, the mental health of survivors of sexual violence.”

“On the Qwaqwa Campus, where we still have some problems with consistent access to data networks, we were pleased to see that our webinars have been well-subscribed to by students and staff members,” reports Siya Magayana, who is the GEADO officer on this campus.

“Each such step makes a big difference by saying that the
lives of survivors matter and by underscoring that
gender-based violence will not be tolerated at the UFS.”

Since 1991, activists around the world have annually coordinated activities around the 16 Days of Activism against Gender-Based Violence. The 16 days of activism begin on 25 November, the International Day for the Elimination of Violence against Women, and run until 10 December, which is International Human Rights Day. The start and end dates signify that the fight to eliminate violence against women advances human rights for all.

Activities to mark the 16 Days of Activism against Gender-Based Violence will be advertised on various UFS communication platforms.

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.
