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.

Conference on religion and reconciliation

2011-07-25

At the conference were, from the left, front: Dr Frank Chikane, President of AFM International; Dr Mathole Motshekga, Chief Whip of the ANC; at the back: Rev. Maniraj Sukdaven, Head of our Department of Religion Studies; and Dr Alan Boesak, connected to our International Institute for Studies in Race, Reconciliation and Social Justice, as well as a minister in the United Reformed Church.

In recent times, reconciliation has mainly been politically driven, Dr Alan Boesak stated during a conference on religion and reconciliation. He was one of a number of prominent academic leaders from various religions who participated in the conference: Exploring religious understanding for reconciliation.The conference was presented by our Faculty of Theology and the International Institute for Studies in Race, Reconciliation and Social Justice at our university this week.

According to Dr Boesak, a theologian connected to our International Institute for Studies in Race, Reconciliation and Social Justice, reconciliation means much more than simply former enemies no longer attacking or killing one another; they also have co-exist with a positive attitude towards one another.

Speakers from, amongst others, the Christian, Jewish, Baha’i, Rastafarian, Islam and Buddhist religious communities shared their views on reconciliation with one another.Most of these speakers referred to the special value of humankind in each religion. A person’s life has a supernatural dimension, which ought to play a major role in the way in which people treat one another.

Dr Frank Chikane, President of AFM International, as well as a speaker at the event, stated that the religious community should and had to be more active in discussions about reconciliation.“If religious leaders do not talk about current issues, all kinds of voices with distorted perspectives will be heard instead,” Dr Chikane added.

Reconciliation can only truly take place if the contribution of each group in society is taken seriously. Apart from the high premium placed on rights in society, duties that have to be fulfilled should also be emphasised. Bishop Malusi Mpumlwana from the Ethiopian Episcopal Church is of the opinion that this sense of duty should be established in people’s frame of mind. Adv. Antony Osler pointed out from a Buddhist perspective how important it was to deal with reconciliation by living up to its principles.

Rev. Maniraj Sukdaven, Head of our Department of Religion Studies, is very satisfied with the high quality of the contributions during the conference.
