Through collaborative agreements with the University of Malawi and the University of Zambia, the University of the Free State (UFS) has established the Research Alliance for Higher Education in Africa (RAHEdA), a dynamic initiative aimed at enhancing research capacity and partnerships within Sub-Saharan Africa.
The collaborative agreements align with the UFS’s Vision 130 strategy in relation to internationalisation, emphasising the important role that intra-African mobility visits play in establishing relationships with universities on the continent. It also fosters knowledge exchange and engagement and allows for careful planning and strategy meetings.
“During these discussions, an ambitious but feasible roadmap was laid out for the next three to five years,” Prof Mkwananzi said. “These activities include online workshops for staff and postgraduate students at all partner institutions, and a new webinar series that focuses on profiling, advancing, and celebrating thought leaders, higher education scholars, and scholarship in Africa.”
The inaugural webinar was held on 21 May 2025. Speaker Prof Siseko Kumalo, Associate Professor at the University of Johannesburg’s Ali Mazrui Centre for Higher Education Studies, spoke on ‘Orality as the Bulwark of the Humanities?’, set the bar high for the webinar series through his compelling and original response to this timely question, as scholars around the world contemplate appropriate responses to the rise and influence of artificial intelligence in higher education teaching, learning, and assessment.
Funding to support RAHEdA has been generously provided by Prof Melanie Walker, Distinguished Professor and SARChI Chair in Higher Education and Human Development.

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.
