The University of the Free State (UFS) is gearing up to be a leading academic institution in astronomical research. The institution successfully mounted a spectrograph with a polarimeter to the Boyden Observatory 1,5-m telescope that will provide scientists with visual access to both the Northern and Southern Hemispheres.

The instrument, which can be accessed from Boyden, an astronomical research observatory and science education centre a few kilometres outside Bloemfontein, will allow researchers such as the Astrophysics Group at the UFS to do simultaneous polarimetry and spectroscopy of astronomical sources. This is vital for the research they are working on.

Mounting the spectrograph to the telescope and installing the polarimeter completed the upgrade of the 1,5-m telescope and is a leap forward for the astrophysics group at the UFS. The upgraded telescope with the spectropolarimeter, with a valued cost of R1.5 million, will also provide unique opportunities for collaborative research between the Astrophysics Groups at the UFS and researchers from the Appalachian State University (ASU). This adds greatly to the astrophysics research capacity at the university.

Prof Richard Gray, who 2019 started with the development of the astronomical spectrograph for the UFS Department of Physics, is a world-renowned expert in stellar spectroscopy, from the Department of Physics and Astronomy at ASU in North Carolina in the US. He was mainly responsible for the development and building of the instrument.

Prof Pieter Meintjes, Senior Professor from the UFS Department of Physics, describes the moment that installation was completed as a feeling of enormous relief. “It took many hours of hard work, planning and testing to marry the 90-year 1,5-m telescope with the new sophisticated instrument,” he says.

Adding value to graduate programme

Besides the development and installation of the spectrograph, Prof Gray also designed and built a polarimeter which can be integrated with the spectrograph. When placed inside the spectrograph, this piece of equipment transforms the spectrograph into a spectropolarimeter, giving it additional functionality. “This allows us, for example, to detect and analyse polarised light. It enables us to study the effect of magnetic fields in astronomical sources which introduce various polarisation signatures that can be detected with the polarimeter,” explains Prof Gray.

“I am fascinated by the polarimetric capabilities that we never had before. It is a great step forward,” remarks Prof Meintjes.

“The Department of Electronics and Instrumentation at the UFS played an enormous role in the building of several components of the instrument that Prof Gray designed, as well as getting the 1.5-m telescope research ready so that the completed instrument could be mounted to the telescope”, says Prof Meintjes

He envisages that the research instrument will be ready for research purposes by March this year. Up till then researchers, graduates, and third-year students will have the opportunity to spend time on the spectrograph to familiarise themselves with it.

“Once installation is finalised, the UFS will be the only academic institution in South Africa with access to a 1.5-m telescope paired with a spectrograph. This gives us an edge in terms of our astrophysics programme and the training we provide our students. It also adds so much value to our graduate programme,” he says.

New instrument provides much flexibility

The spectrograph offers Prof Meintjes many possibilities for his research, and he is eager to put the instrument to use. To study binary systems as well as the jets of Active Galactic Nuclei (AGN), you need a spectrograph, preferably with polarimetric capabilities. It can also be applied to finding elements at the surface levels of stars so that their chemical composition can be determined.

“In the past, we needed to send our researchers to Sutherland and they were never guaranteed clear skies. Having this facility gives us so much flexibility,” he says.

Prof Brian van Soelen from the Department of Physics will be a key user of the spectrograph for his research. He is also playing an important role in terms of postgraduate training and research where the spectrograph is applied.

The polarimeter converts the spectrograph to a spectropolarimeter. This instrument, which is mounted on a telescope (in the case of the UFS, it is mounted on the Boyden 1,5-m telescope) enables the user to detect whether radiation from astronomical objects are polarised and to analyse the level of polarisation of the light. Scientists can then, for instance, study the effect of magnetic fields in astronomical sources, which introduce various polarisation signatures (typically with a characteristic level of polarisation).

UFS Communication and Brand Management receives two prestigious international awards

2015-07-07

Lelanie de Wet, Lacea Loader and Leonie Bolleurs

The Department of Communication and Brand Management at the University of the Free State (UFS) received two of the six Gold Quill Awards – that were awarded to South African companies and institutions - at the International Association of Business Communicator’s (IABC) Excellence Gala ceremony in San Francisco, US on 15 June 2015.

The awards ceremony formed part of the 2015 IABC World Conference, which took place from 14-17 June 2015. The department received a Gold Quill Excellence Award for its social media campaign, UFS #FaceOfFacebook and a Gold Quill Merit Award for the B Safe Take Action campaign.

From the 15 countries that entered, a total of 120 Gold Quill Excellence awards and 189 Gold Quill Merit awards were awarded. Other South African award winners included Barclays Africa Group Limited, Mediclinic and the Cape Peninsula University of Technology (CPUT).

This is the second year in a row that the UFS has been recognised by the IABC for its communication projects. In 2014, the department was awarded the Jake Wittmer Research Award for a Stakeholder Perception Audit conducted in February 2014. The audit was considered – by the IABC - as one of the best breakthrough strategies used by a university to measure the perceptions of its stakeholders.This made the UFS the first tertiary institution in Africa to receive the research award. The stakeholder perception audit also received an Africa Gold Quill in 2014.

"Being recognised by a global association such as the IABC for the second time, is a great honour and I am very proud of what my colleagues have achieved by entering the two campaigns. Winning the awards is a true indication of what can be done when a team of expert communicators is committed towards engaging their target audiences with campaigns that speak of quality and innovation. The fact that the UFS is one of only two tertiary education institutions in the country to receive these prestigious awards, makes it even more special," said Lacea Loader, Director: Communication and Brand Management at the UFS.

IABC World and Africa conferences 2015

The IABC is a global membership association with a network of 12 000 members in more than 80 countries, representing many of the Global Fortune 500 companies. It serves professionals in the field of business communication, bringing together the profession’s collective disciplines.

With the theme: Changing landscape: Informing the future, the 2015 world conference was attended by over 1 200 delegates from across the world. Delegates were offered an opportunity for learning, discovering, and connecting. Loader also made a presentation entitled ‘Award-winning measurement endorses sound reputation management strategy’ at the world conference.

The department will also be receiving two Africa Gold Quill Awards from the Africa chapter of the IABC for the same campaigns on 30 July 2015 in Johannesburg.

UFS #FaceOfFacebook Campaign

The university received a Gold Quill Excellence Award for its social media campaign, UFS #FaceOfFacebook. This initiative originated in the university’s commitment to its Human Project, which sets the standard for good behaviour and care.

Lelanie de Wet, Manager: Social Media and Website Content and project leader of UFS #FaceOfFacebook, said the project was born from the need to communicate with students. Thus a virtual friend, #FaceOfFacebook, was created. “Yearly auditions are being held to choose the new face representing the UFS on Facebook. Short video clips of the #FaceOfFacebook – whether it is attending events or communicating important messages - are posted on the UFS Facebook page. The successful candidate holds the title #FaceOfFacebook for 12 months.

“When I look at a campaign such as #FaceOfFacebook, from the time it took its first tentative steps in 2013, and see how it inspired staff and students alike, my heart swells with pride. Often you can see the impact you have made only in retrospect. The ripples you send into the world will inevitably create waves,” she said.

B Safe Take Action Campaign

The B Safe Take Action campaign of the university received a Gold Quill Merit award from the IABC.

The campaign was activated in September 2013. “It targeted on- and off-campus students and staff, aiming to create social ownership of personal safety, and to raise awareness of the safety measures put in place by the university,” said Leonie Bolleurs, Manager: Internal Communication and project manager of the campaign.

The campaign looked at a number of safety aspects, focusing not only on crime but also on being safe from road accidents and stress/burnout.

It is the second time this year that the BSafe campaign has been recognised for its innovative strategy. Earlier this year it received a PRISM Award (Gold) from the Public Relations Institute of Southern Africa (PRISA). The annual PRISM Awards are about recognising and celebrating great public relations campaigns.
