Prof Francis Petersen speech
“We can create an institution that operates and lives in the times of embracing and celebrating diversity, inclusivity, and academic excellence by ensuring that students own their time at university,” said Prof Francis Petersen.

25 January 2019 marked the official welcoming of the University of the Free State’s (UFS) first-year students, as they moved into their respective residences and were warmly welcomed on the UFS Bloemfontein Campus. This day also marked the start of the registration process for first-year students.

According to first-year Psychology student Keisha Claasen, who moved into her residence earlier on 25 January, her first experience of the UFS was daunting but exciting, as she had never been in a similar environment. According to Given Gwerera, who dropped his son off at the Karee residence earlier the day, “the UFS is an institution with great culture and an overall good academic record.” He further explained that he trusts his son to make full use of the opportunities presented to him, as he has a cool head on his shoulders.

On the evening of 25 January, an eager group of millennials, joined by their parents, took the first sip from their cup of varsity life as they assembled on the Red Square of the Bloemfontein Campus to meet the Rector and Vice-Chancellor, Prof Francis Petersen, members of Rectorate, the deans of all faculties, and the Student Representative Council (SRC) of the UFS.

“2019 will be a year of continued change; the UFS is thrilled about the prospect of bringing about opportunities for adaptation and realignment to the future,” said Prof Francis Petersen.

He further explained that the university prides itself in moulding its students into well-rounded individuals who will develop into globally competitive graduates as required in a diversity of landscapes. Prof Petersen urged first-years to remain open to the technological developments that go with globalisation, because of its permanent effects on society today.

First-years were further advised to take advantage of the rich pool of academic research and knowledge that is characteristic of the university and is piloted by UFS scholars, by engaging with and learning from them.

The inspiring night concluded on a colourful note, as the audience enjoyed an artistic laser show in front of the Main Building. Caption:

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.
