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.

Visiting Professor, Piet Bracke, Speaks on Public Mental Health
2015-02-20

Piet Bracke

Professor in the Department of Sociology at the Ghent University in Belgium, Piet Bracke, recently visited the UFS to speak about his research on the Public mental health and comparative health research: between social theory and psychiatric epidemiology.

At the public lecture on Monday 16 February, Bracke stated that part of the sociological attention to mental health and well-being was rooted in the 19th century's romanticists' discontent with self and society. The classical and contemporary social theorists' views on the disconnection between culture and the ‘real’ self resembles the more recent evolutionary psychological assumptions about the maladaptation of  psychobiological mechanisms to contemporary societal arrangements.

In contrast to these perspectives, contemporary psychiatric epidemiological research has a strongly underdeveloped conception about the nexus between society and population mental health. Both perspectives, the social-theory-and-societal-discontent approach and the biomedical psychiatric epidemiological approach, have drawbacks. Starting from the pitfalls of the aforementioned perspectives, they have been exploring the challenges posed by the development of a macro-sociology of population mental health.

Recently, this research domain has received renewed attention of scholars inside as well as outside sociology. The rise of multi-country, multilevel datasets containing health-related information, as well as the growing attention on the fundamental social causes of health and illness, and the focus on population as opposed to individual health, has contributed to the revival of comparative public mental health research. Based on findings from their recent research, they have illustrated how taking the context into account is vital when exploring the social roots of mental health and illness. In addition, they have demonstrated how they can liberate a few so-called ‘control variables’ in risk factor epidemiology – e.g. gender, education, and age – from their suppressed status by linking them to core concepts of sociology. With their research, they hope to further the development of a macro-sociology of public mental health.
