June 2018 graduates from the University of the Free State (UFS) Bloemfontein Campus are beginning to prepare for their upcoming graduations. The ceremonies are scheduled to take place at the Callie Human Centre from Wednesday 27 June until Friday 29 June 2018.
The UFS plans to document and highlight the special moments that graduates encounter at this time. A daily update accompanied by photos will be available on the UFS website.
Visit the UFS graduation ceremonies page for more information on the upcoming events. Graduates and students are free to familiarise themselves with the Graduation Guide Booklet which stipulates the necessary information for students to note during the graduation processions.
The Graduate Career Guide is also of vital importance as it equips graduates with fundamental knowledge and practical advice about preparing for the world of work.
A livestream link will be provided for the different graduation processions closer towards the time.
Graduation ceremonies for the different faculties take place on the following dates:

H.E.S.S. (High Energy Stereoscopic System) scientists publically revealed their latest galactic discovery in the international science journal, Nature, on 16 March 2016. These scientists were able to pinpoint the most powerful source of cosmic radiation – which, up to now, remained a mystery.
Part of this team of scientists are Prof Pieter Meintjes and Dr Brian van Soelen, both in the University of the Free State (UFS) Department of Physics. Dr Van Soelen explains that they have discovered a proton PeVatron – a source that can accelerate protons up to energies of ~1 PeV (10^15 eV) – at the centre of the Milky Way. The supermassive black hole called Sagittarius A has been identified as the most plausible source of this unprecedented acceleration of protons.
The protons are accelerated to Very High Energy (VHE) gamma rays. The energy of these protons are 100 times larger than those achieved by the Large Hadron Collider at CERN (the European Organization for Nuclear Research).
According to Dr Van Soelen, the fact that this research has been published in Nature demonstrates the importance and pioneering nature of the research conducted by H.E.S.S. The H.E.S.S. observatory – operational in Namibia – is a collaboration between 42 scientific institutions in 12 countries.
In 2006, H.E.S.S. was awarded the Descartes Prize of the European Commission – the highest recognition for collaborative research – and in 2010 the prestigious Rossi Prize of the American Astronomical Society. The extent of the observatory’s significance places it among the ranks of the Hubble Space Telescope and the telescopes of the European Southern Observatory in Chile.
“The next generation VHE gamma-ray telescope,” Dr Van Soelen says, “will be the Cherenkov Telescope Array (CTA), which is currently in the design and development stage.” Both Dr Van Soelen and Prof Meintjes are part of this project as well.
H.E.S.S. has issued a complete statement about the paper published in Nature.
