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.

Leah Tutu - from a humble heritage to a matriarch of devotion

There are treasures in life, but owners are few
Of money and power to buy things brand new
Yet you can be wealthy and feel regal too,
If you will just look for the treasures in you …

The joy and the laughter, the smile that you bring;
The heart unafraid to love and to sing;
The hand always willing to help those in need;
Ones quick to reach out, to labour and feed.

So thank you for sharing these great gifts inside;
The caring, the cheering, the hug when one cried.
Thanks for the energy, encouragement too,
And thank you for sharing the treasures in you. (Author unknown)

With these words, Thandeka Tutu-Gxashe embodied the celebration in honour of her mother, Leah Tutu.

On Thursday 17 October 2013, the Annual Intercontinental Leah Tutu Symposium was launched at the UFS’ Bloemfontein Campus. Dignitaries and students alike flocked to the Centenary Hall where friends and family shared their immense love and respect for Ms Tutu.

Approaching the podium, Eunice Dhadhla (co-founder with Ms Tutu of the Domestic Workers Union) started humming and in an instant the audience had risen to their feet and the words “My mother was a kitchen girl. My father was a garden boy. That’s why I’m a unionist”, reverberated through the hall.

“I am what I am today because of her,” Dhadhla said of Ms Tutu. They have walked a long hard road together to ultimately unite domestic workers across the globe. Stretching her small body to its full length, Dhadhla imparted one of the most valuable lessons she has learned from Ms Tutu, “Stop crawling, stand up and walk for yourself.”

As soon as Dr Sindiwe Magona – acclaimed writer and poet – ascended the stage, her energy rushed across the room with electrifying intensity. Her high regard for Ms Tutu as public icon as well as a mother, wife and friend, was palpable. Belting out line after line of a poem she wrote especially for Ms Tutu, the audience echoed their agreement in a mutual exchange.
No sooner were they seated, than Archbishop Desmond Tutu and Prof Jonathan Jansen had the crowd roaring with laughter. Archbishop Tutu’s familiar chuckle peppered his story of how he came to propose to his wife. It was clear, though, how much he reveres Ms Tutu’s presence in his life. With enormous awe, he revealed her innate power, specifically during difficult times in our country’s past – from weathering death threats against her husband to public humiliation.

But despite adversity and heartache, in front of the Centenary Hall, this matriarch stood up and beamed joy into everyone present.
