The University of the Free State Qwaqwa Campus is celebrating a significant boost to its academic and research standing with the recent achievement of National Research Foundation (NRF) ratings by several esteemed academics. These ratings not only recognise the individual accomplishments and impact of these researchers but also underscore the campus' commitment to Vision 130 and the university's overarching strategy for academic and research excellence.

The Deputy Vice-Chancellor: Research and Internationalisation, Prof Vasu Reddy, explained the ratings, saying, “Ratings embody high ideals and recognition of scientific merit and impact in a knowledge-intensive economy, aligned with the UFS’ aspirations.”

Prof Jared McDonald, Assistant Dean of the Faculty of The Humanities, Dr Calvin Mudzingiri, Assistant Dean of the Faculty of Economic and Management Sciences, and Prof Richard Ocaya from the Department of Physics have all been awarded C2 ratings, signifying that they are established researchers with considerable international recognition for the quality and impact of their research outputs. This level of recognition highlights their consistent contribution to their respective fields and positions them as key players within the global research landscape.

Building on this impressive achievement, Prof Aliza le Roux, Assistant Dean of the Faculty of Natural and Agricultural Sciences, has attained a C1 rating, indicating that she is a leading international researcher recognised for the high quality and impact of her recent research outputs. This prestigious rating stresses Prof Le Roux's significant contributions and her standing as a prominent figure in her area of expertise.

Adding to the growing cadre of research talent on the Qwaqwa Campus, Dr Nthatisi Nyembe, Lecturer in the Department of Zoology and Entomology, and Dr Victor Gwande – Senior Lecturer in the Department of History – have both received Y1 ratings. Dr Regret Sunge, Lecturer in the Department of Economics and Finance within the Faculty of Economic and Management Sciences, has received the NRF Y2 rating for the period 1 January 2025 to 31 December 2030. This rating is awarded to promising young researchers who have demonstrated the potential to establish themselves as researchers with strong international recognition within five years after obtaining their doctorates. These Y1 ratings signal a bright future for research on the campus, highlighting the emergence of a new generation of impactful scholars.

NRF ratings are a crucial benchmark within the South African academic and research sector. They provide a peer-review assessment of the quality and impact of researchers' work, lending credibility and prestige to both the individual and their institution. For academics, a strong NRF rating can enhance their research collaborations, funding opportunities, and overall academic standing. For the institution, a growing number of rated researchers reflects a vibrant research environment and contributes to its reputation as a leading centre of knowledge production.

These achievements align directly with the UFS' Vision 130, which aims to elevate the university's academic and research profile, fostering a culture of innovation and impactful scholarship. The success of these Qwaqwa Campus academics demonstrates the tangible progress being made towards realising this vision and strengthening the university's strategic goals in academic and research excellence.

The UFS is committed to nurturing and supporting its academics in their research endeavours. Initiatives such as the Future Professoriate Programme and the Emerging Scholars Advancement Programme (ESAP) play a vital role in providing mentorship, resources, and opportunities for academics to develop their research careers and achieve their full potential. The recent NRF ratings are a testament to the effectiveness of these support structures and the dedication of the academics on the Qwaqwa Campus.

The University of the Free State proudly celebrates the accomplishments of Prof McDonald, Dr Mudzingiri, Prof Ocaya, Prof Le Roux, Dr Nyembe, Dr Gwande, and Regret Sunge. Their success is a source of inspiration for the entire university community and reaffirms the Qwaqwa Campus' growing prominence as a hub of impactful research.

In his congratulatory remarks, Prof Reddy said: “Our colleagues’ ratings confirm their dedicated and sterling work in advancing research and innovation. It is commendable to also see academic leaders in professional support being beacons to inspire others.”

He further commented: “We value your hard work and determination. Congratulations, you make us proud as a university. You inspire us all to follow you and we support you in reaching our research-intensive goals. We are confident that your ratings will inspire you, personally and professionally – as well as other colleagues – to grow further. Your efforts will help us as we move to new heights,” Prof Reddy concluded.

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.
