The Astrophysics Research Group in the UFS Department of Physics recently collaborated with the Institute of Astrophysics of Andalusia (IAA) in Spain and the University College of Dublin (UCD) in Ireland, to install a robotic telescope at the Boyden Observatory.

The Astrophysics Research Group in the Department of Physics at the University of the Free State (UFS) is part of an international collaboration with the Institute of Astrophysics of Andalusia (IAA) in Spain and the University College of Dublin (UCD) in Ireland, which focuses on measuring the brightness of transient sources. Knowledge gained from studying these cosmic X-ray sources, which seem to appear in the sky for a short time before disappearing, will lead to a more complete and better understanding of the universe, believes Prof Pieter Meintjes, Professor of Physics and Head of the Astrophysics Programme in the Department of Physics.

To facilitate these observations, a robotic telescope network has been established, with the Boyden Observatory selected as one of the sites for BOOTES 6 (a Burst Observer and Optical Transient Exploring System).

The UFS and the IAA started working on this project more than two years ago. The foundation and pier were built through a local tender, and in January 2020, part of the dome of the structure housing the telescope arrived by ship. Due to the COVID-19 pandemic there were some delays, resulting in the crew from Spain only arriving in South Africa with the telescope and hardware in November 2021, but having to return to their country without completing the installation. They returned in April, and in early May completed assembling the telescope in collaboration with UFS researchers and technicians.

Robotic telescope opportunity to further own research

The main scientific objective of the robotic telescope is to observe and monitor the optic counterparts of gamma-ray bursts as quickly as possible when detected from space or other ground-based observatories.

Prof Meintjes says they will use the telescope to observe these transient sources that goes into an eruptive phase for a short span of time. “Since BOOTES has an enormously fast slew rate, it can start observations of erupting sources within a few seconds, which allows the Astrophysics Research Group to get data very quickly. This will certainly give us an edge over other international astronomy groups that are also involved in the same type of research,” says Prof Meintjes, the local coordinator of the project who is overseeing the whole operation locally. 

He explains the importance of monitoring these packets of enormous energy. “By observing the optical afterglow of the gamma-ray bursts, we can establish its point of origin in space. Furthermore, the shape of the optical afterglow light curve gives insight into the type of mechanism behind the gamma-ray burst, i.e., whether the burst is produced by a collision between two neutron stars or by the explosion of a hypernova event.” 

The knowledge gained with research made possible by the robotic telescope will lead to a more complete and better understanding of the universe. – Prof Peter Meintjes

The UFS Astrophysics Research Group, with its research focus on high-energy astronomy and the physics behind gamma-ray bursts, has a particular interest in this project. As the local custodians of the project and in terms of a memorandum of understanding, the group is guaranteed a certain amount of telescope time for its own in-house observation programmes.

Project expands UFS’ international research footprint

Besides the opportunity for knowledge exchange, this project establishes Bloemfontein as a region where research of international quality is being done and will help to attract talented learners to the UFS. “The successful operation of the robotic telescope may also draw more international groups to bring robotic telescopes to Boyden, thus expanding our international research footprint,” he adds. 

The fact that the Boyden Observatory is in the Southern Hemisphere and has access to the galactic centre region with its host of very interesting astronomical objects and the Magellanic Clouds, makes it a very attractive site for astronomical research,” says Prof Meintjes.

“We also have a number of years of experience in robotic telescopes in the sense that we have been hosting the Watcher telescope, operated by the University College Dublin in Ireland, since 2001. Once mounted in middle May 2022, this will then be Boyden’s second robotic telescope.”

UFS takes steps to address power shedding
2008-01-31

The problem of power shedding was urgently discussed by the Executive Committee of the Executive Management (Exco) during its meeting yesterday.

A report was presented by Ms Edma Pelzer, Director: Physical Resources and Special Projects, and a consulting electrical engineer about possible short, medium and long term solutions for the UFS.

This includes (a) the possible installation of equipment (eg. power generators) and (b) operating procedures to ensure the UFS’s functionality despite power shedding.

We are also in contact with Centlec to bring about the best possible arrangements for the UFS regarding the power shedding. It is possible that refined power shedding schedules will be implemented within a few weeks or a month to ensure that there is minimal disruptions at the UFS (especially during evening lectures).

In the long term it is unaffordable to generate power for the whole campus to meet everyone’s electricity needs. Only critical points will be supplied with emergency power generators.

Emergency power generation for certain critical points have already been provided for (eg. the Callie Human Centre, the evacuation of large halls, computer services, critical long term research projects, etc.). We have been doing surveys since 2006 to determine the UFS’s preparedness for “normal” power failures. The extent of the current situation has, however, taken the whole country by surprise.

Certain urgent steps were decided on yesterday. A decision was made to immediately design emergency power systems and supply it to the new examination centre and large lecture halls such as the Stabilis, Flippie Groenewoud, Agriculture building, and possibly the West Block. The delivery and installation of these systems will, however, take from three to six months.

The UFS will have to manage despite the power shedding, even after the emergency power systems have been installed and we will not be able to function as normal. Every division must devise operating procedures to deal with the power shedding without jeopardising the quality of core functions.

Bloemfontein is luckier than many other cities because Centlec is able (so far) to keep to the published schedule to a large extent.

Plans are also being made to keep staff and students continuously informed via the UFS web site about expected power shedding schedules and risks of power shedding in the course of a day.

Exco requests every faculty and support service to think about suitable operational solutions for managing their work and meetings during a power shedding.

Every line head has instructions to urgently determine the situation and needs in his or her division and indicate what practical arrangements can and must be made to schedule work around the power shedding. Every line head must provide Exco with a status report within a week.

In this way critical areas in terms of core functions and high quality service delivery will be determined and receive attention. Security systems and the safety of staff and students will also receive specific attention - this includes the residences.

In the mean time the Department of Physical Resources will carry on with a wide-ranging investigation into the extent of needs and plans and will compile a budget for the solution thereof.

Prof. Teuns Verschoor, Vice-Rector: Academic Operations, and the deans had a meeting yesterday to discuss problems and possible solutions around the power shedding in eg. computer rooms, during evening lectures, and practical classes.

Options may include eg. alternative time slots (eg. weekends) or alternative halls (eg. at the Vista Campus) for evening lectures which are affected by power shedding, or adjusted teaching methods.

Staff is requested not to install their own power generators under any circumstances. It can be very dangerous when such apparatus are linked to a building’s electrical system. The safety of staff and students and the risks of fire or injuries must also be the highest priority under all circumstances.

The Department of Physical Resources is also in the process of investigating options such as smaller power generators or ‘UPS’ apparatus as part of a broader evaluation of needs and potential solutions.

Exco wants to ensure all staff and students that this matter is receiving urgent attention and will keep on receiving it.

If there are any practical solutions about dealing with the power shedding (such as alternative ways of working) you are invited to send an e-mail to: lightsout@ufs.ac.za
