Legae first-year residents welcomed on UFS South Campus

On 27 January 2018, several dozen eager first-year students and a large number of their parents crowded into the venue at the Legae residence on the South Campus of the University of the Free State (UFS). They were welcomed by Gali Malebo, the Residence Head, Prof Daniella Coetzee, the Principal of South Campus, and Prof Francis Petersen, the Rector and Vice-Chancellor of the UFS.

Prof Coetzee exhorted the students to show their seriousness about studying by giving their best and being accountable for their own learning experience. She said that she enjoyed the very positive vibe from the excited and enthusiastic students. Prof Petersen also addressed the students and advised them to make full use of the facilities made available to support and assist especially first-years.

Gali Malebo said of the occasion: “I am pleased that what we planned was so successful, and I feel blessed that both Prof Petersen and Prof Daniella [Coetzee] were present to share such beautiful moments with us. I am grateful to my team of Residence Assistants who worked very hard to make sure that everything was in order. They received several expressions of appreciation from parents for their hospitable, welcoming spirit and for making the first-years feel at home, especially for those who travelled from far.”

Prof Coetzee concluded with these words, “The UFS is a space for freedom, opportunities, and responsibilities. Use each day to reach out for knowledge. The university is a place where you are supposed to be active in seeking out the knowledge you need, a place where you are supposed to struggle and strive in order to excel. Do not give up until you have explored the limits of your intellectual ability. We expect much of you, and you should expect much of us.”

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.
