Stable atmospheric environments and near perfect weather conditions were the main reasons for the establishment of the Boyden Observatory a few kilometres outside Bloemfontein. This astronomical research observatory and science education centre is managed by the Department of Physics at the University of the Free State (UFS).

With the newly acquired astronomical spectrograph for the Boyden Observatory 1,5-m telescope, scientists will be able to gain visual access to both the Northern and Southern Hemisphere skies.

Collaboration with expert in stellar spectroscopy 

The spectrograph, mainly developed and built by Dr Richard Gray, will be used collaboratively for astronomical research by the UFS and the Appalachian State University (ASU) in North Carolina, where Dr Gray is based. 

Dr Gray is a world-renowned expert in stellar spectroscopy and leading author of one of the most influential textbooks on stellar spectroscopy, Stellar Spectral Classification, with co-author Christopher J Corbally.

Dr Gray recently received a Fulbright Scholarship from the Fulbright Foundation to spend a full year in the UFS Department of Physics, where he will lecture several Astronomy classes and do research in collaboration with personnel of the UFS Astrophysics Research Group. He will also lead the assembly of the instrument over the next few weeks, working with personnel and students in the Department of Physics as well as the UFS Instrumentation Division.

According to Prof Pieter Meintjes, Senior Professor from the UFS Department of Physics, some components of the instrument have been developed and constructed by the university’s Instrumentation Division, with key components purchased from funding by the Directorate: Research Development at the UFS.

Unique capability in infrastructure 

“The availability of a sophisticated instrument of this nature on the 1,5-m telescope will place the UFS Astrophysics Group in an elite bracket in terms of the available infrastructure for astronomical research,” said Prof Meintjes.

He explained: “The combined polarimetric-spectroscopic capability in one single instrument is unique. Combined with the fact that it is hosted on a research instrument that is utilised and maintained exclusively by the UFS Astronomy Group in the Department of Physics, gives this group a competitive edge in relation to most international astronomy groups.” 

The instrument is valued at close to R1,5 million.

According to Prof Meintjes, the instrument will be mounted at the backend of the UFS Boyden 1,5-m telescope and will allow them to do simultaneous polarimetry and spectroscopy of astronomical sources. “This is vital for the research we are working on,” he said.

International collaboration and student development

The instrument also brings with it the possibility of forging international collaborations for research as well as student development. “This can advance the stature of the UFS as an internationally respected research-led tertiary institution,” said Prof Meintjes. 

The possibility of making the UFS Boyden 1,5-m telescope completely remote-controlled, is being investigated. “This will serve the observational needs of researchers from both the UFS and the ASU, with researchers at ASU able to access the telescope for their own in-house research programmes. The availability of such an instrument on the UFS 1,5-m telescope also opens up the possibility to accommodate visiting researchers from ASU or elsewhere in the world at Boyden,” said Prof Meintjes.

Prof Tim Murithi calls for Africa to design new global order

“What do Africans have to say about the remaking of the global order?” was the opening question of Prof Tim Murithi’s lecture which was hosted by the Centre for Africa Studies (CAS) of the University of the Free State (UFS) to celebrate Africa Day on 25 May 2016.

The annual Africa Day Memorial Lecture, entitled: Africa and the Remaking of the Global Order, doubled as Prof Murithi’s inaugural lecture. He is CAS’s newly-appointed Extraordinary Professor, as well as the Head of the Justice and Reconciliation in Africa Programme at the Institute for Justice and Reconciliation in Cape Town. He made a compelling argument for the need for Africa to exert an active influence on international narratives of peace, governance, justice, and reconciliation.

“If we are waiting for American leadership to get us out of the quagmire of a situation we are in, we will be waiting for a long time,” said Prof Murithi.

The Head of the Centre, Prof Heidi Hudson, concurred with Prof Murithi’s suggestion of devising African solutions for African problems. She quoted Audre Lorde’s well-known assertion that “The master’s tools will never dismantle the master’s house.”

Remembering 1963
Over five decades ago, on 25 May 1963, the Organisation of African Unity was formed, and was renamed the African Union in 2002. Africa Day marks this pivotal point in the continent’s history. On this day, we reflect on the continent’s journey into democracy, peace, stability and socio-economic development. It is also an opportunity to celebrate African identity and heritage.

Continent-building dialogues
The UFS Sasol Library celebrated Africa Day with a book launch. Facets of Power. Politics, Profits and People in the Making of Zimbabwe's Blood Diamonds by Tinashe Nyamunda is a reflection of some of the challenges that Zimbabwe continues to face. It details the disadvantaged position which the country finds itself in due to greed, maladministration, and corruption, despite possessing large deposits of minerals.

In celebration of Africa Month, CAS has held a series of lectures by esteemed scholars from across the globe.  Earlier in the month, Prof Henning Melber presented lectures on Namibia’s independence and the African middle class. Kevin Bloom and Richard Poplak unpacked the issues surrounding Africa’s continental shift, while Prof Joleen Steyn Kotze focused on the possible fall of the African National Congress.
