Global Citizen - In conversation with Rohitesh Dhawan

23 October 2023 | Story Carmenita Redcliffe-Paul

The University of the Free State (UFS) and the South African Chamber of Commerce United Kingdom (SACC UK) are pleased to invite you to the next conversation of the Global Citizen Series.

SACC UK representative, Director of Mindofafox, futurist, and bestselling author, Chantell Ilbury, will facilitate this thought-provoking and engaging conversation between UFS Vice-Chancellor and Principal, Prof Francis Petersen, and President and Chief Executive of the International Council on Mining and Metals (ICMM), Rohitesh Dhawan.

The discussion will explore the strategic priorities and breakthroughs in the mining and metals industry in relation to critical areas of climate and environmental resilience, social performance, governance, ethics and transparency, and innovation for sustainability.

Dhawan, a Fellow and faculty member of the Africa Leadership Initiative, will reflect on leadership through collaboration to enhance the contribution of mining and metals towards sustainable development, security of minerals within a changing geopolitical environment and the progress that is possible when citizens collectively focus on improving the lives of others and our planet.

Two scientists part of team that discovers the source of the highest energy cosmic rays at the centre of the Milky Way

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.
