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 application figures show a good upward trend
2008-10-23

Applications for admission to the University of the Free State (UFS) are showing an upward trend. In comparison with the same time last year, the total application figure has increased from 6 273 to 7 507 – a growth of 19,7%.

So far, applications for postgraduate studies are showing the biggest growth with 1 342 applications received. During the same time last year, 594 applications for postgraduate studies were received – an increase of 126%.

Prospective students have until 30 November 2008 to apply for admission. “This applies to first-time entering first-year students and senior students who have interrupted their studies for at least one year,” said Mr Vernon Collett, Registrar: Student Academic Services, at the UFS.

According to Mr Collett students whose applications for admission are received after 30 November 2008 and until 13 January 2009 will be accepted subject to the availability of place on the programme they applied for.

Applications from prospective students who wrote the Senior Certificate (prior to 2008) and who are in the possession of a conditional exemption will only be accepted until 5 January 2009.

Prospective students who want to apply must pay a non-refundable fee of R140.
The signed application form must be accompanied by a certified copy of the prospective student’s identity document or passport, a proof of payment of the application fee as well as a certified copy of their Statement of Results of their Senior Certificate.

Prospective students who are in Grade 12 this year will receive a National Senior Certificate. A certified copy of their Statement of Results must be faxed to the UFS not later than 7 January 2009.

The application form of a minor must be signed by his/her parent or guardian and the field of study should be clearly indicated.

First-time entering first-year students from the Faculties of Economic and Management Sciences and the Humanities (including Education) will be welcomed by the Acting Rector, Prof. Teuns Verschoor, on Friday, 9 January 2009 at 09:00 in the Callie Human Centre on the Main Campus.

The welcoming of students from the Faculties of Health Sciences, Natural and Agricultural Sciences, Law and Theology will take place on Saturday, 10 January 2009 at 09:00 in the Callie Human Centre.

The registration of first-time entering first-year students will commence on 13 January 2009 and that of senior students on 19 January 2009 at the Callie Human Centre according to a programme.

Students who applied for admission after 30 November 2008 and are accepted can register from 4 February 2009.

Lectures will commence on 2 February 2009 and the registration process will end on 10 February 2009. This is applicable to all students – undergraduate as well as postgraduates

Prospective students who want to apply for admission or who have any enquiries can call 051 401 3000 or visit the UFS web site at www.ufs.ac.za.
