Choir
The UFS Bloemfontein Campus, South Campus, and Qwaqwa Campus choirs are student-centred choirs functioning under the Student Affairs’ Arts, Culture and Dialogue office.

It has been a noteworthy year for the University of the Free State (UFS) Choir, establishing itself on the student/university choir scene. The choir, based on the Bloemfontein Campus, represented the UFS at the bi-annual KUESTA choir festival earlier this year, showcasing its musical talent. The choir shared a stage with other university choirs from around the country.   

The UFS (Bloemfontein Campus) Choir is a 42-member ensemble of students; the other two choirs, based on the South and Qwaqwa campuses, consist of 40 and 62 members respectively. The choirs are administered and managed by the Division of Student Affairs’ Arts, Culture and Dialogue Office. In addition to Kovsie culture, the choirs strive to have a varied repertoire of inclusive music, with the UFS BFN Campus choir performing a diversity of songs in English, Afrikaans, isiXhosa, and Sesotho. 
 
The new South Campus choir was established in 2018 and is led by choir director, Bonisile Gcisa, who specialises in choral music. This leg of the choir will therefore perform many of his works, but will also include some of the Bloemfontein choir’s set lists, since most of the choir members will be auditioning in 2021 for the Bfn choir when they change campuses. 
 
The Qwaqwa Campus choir will lean more towards a choral genre under the direction of Sipho Khumalo. 
 
The UFS Bloemfontein Campus choir was officially re-established under the leadership of choir conductor Leona Geldenhuys in March 2018, and has performed at several events, including the Rector’s Concert, the annual KUESTA choir convention, and the Bloemfontein Choir invitational. The group has also held a number of public performances on the Thakaneng Bridge at the UFS Bloemfontein Campus.  
 
“Part of the UFS Student Affairs’ objective is to create an inclusive and a socially just student lived experience, and that is the mandate the choirs will also adopt. We hope to create an experience that not only enhances our students’ singing abilities, but also contribute to a more inclusive university experience.” – Angelo Mockie – Director: UFS Student Affairs Arts, Culture and Dialogue office. 

“Rest well, be safe, and return rejuvenated,” were his parting words to students for the festive season.

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.
