Geraldine Lengau, Senior Officer in the UFS Gender Equality and Anti-Discrimination Office within the Unit for Institutional Change and Social Justice, calls on men to take the lead in ending gender-based violence.

Gender-based violence is a phenomenon deeply rooted in gender inequality and the scourge continues to be one of the most notable human rights violations, with many communities – especially women and children – suffering the most from the atrocious acts. 

South Africa remains the country with the highest number of violent acts, especially against women, and Statistics South Africa reports that one in five partnered women has experienced physical violence. 

Gender-based violence can take many forms, including 

• sexual harassment; 
• rape and/or sexual violence;
• stalking (deliberately and repeatedly following, watching, and/or harassing another person);
• physical, emotional, and economic abuse; and
• child abuse.

Geraldine Lengau, Senior Officer in the Gender Equality and Anti-Discrimination Office within the Unit for Institutional Change and Social Justice, says: “Individuals must be vigilant of toxic environments where emotional and physical abuse are rampant.”

 “Even in the workplace, individuals can experience gender-based violence and it can play itself out in the form of power dynamics, prejudice, and discrimination.”

To help end gender-based violence at work, Lengau says, “Institutions have a duty to implement policies and procedures to increase awareness and sensitisation about this pandemic.”

Societal norms often contribute to victims deciding not to report these criminal acts for fear of being judged, with many women still being considered guilty of attracting violence against themselves through their behaviour.

“It is important for communities to provide support to victims and for organisations to have a zero gender-based violence tolerance policy. Victims must report any act, and in extreme cases, they must not be shy to get a protection order,” Lengau says. 

With the 16 Days of Activism for No Violence against Women and Children Campaign in full swing, Lengau says, “It is a great international initiative to tackle and raise awareness around issues of gender-based violence; however, it is not enough. It should go beyond the 16 days.”

 “To rid society of gender-based violence, our communities – men and women – should work together to root it out. Men should take the lead in tackling issues and bringing about solutions. Women should never get tired of speaking out; there is help for them.”

“Gender-based violence is a societal ill and women need to know that they should not bear the shame,” she says.

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.
