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 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.”

Minister Jeff Radebe commends UFS for measures taken to address racial prejudices

Minister Jeff Radebe lecture: YouTube video

Mr Jeff Radebe, Minister of Justice and Constitutional Development, last night delivered a lecture in the Prestige series of the Dean: Faculty of Law, at the Bloemfontein Campus of the University of the Free State (UFS).

In a packed hall with, among others, university students, staff and members of the judicial system, Minister Radebe said that many other academic institutions should look to the UFS when they deal with the challenges of racism in its various manifestations in their midst. “I commend the university for taking drastic measures to address the challenges of racial prejudices in its own backyard,” he said.

“Government can and must provide leadership, but it is the collective efforts of all our people that will ensure that we bridge the racial and historical divides that stand in contrast to our noble virtues as entailed in the Constitution,” the Minister said.

On the topic “Access to Justice” the Minister said that the Department of Justice and Constitutional Development has channelled more than 80% of its nearly R16 billion budget to the Access to Justice programme.

Minister Radebe talked about the reintroduction of the Sexual Offences Courts, which attests to the unrelenting resolve to eliminate the scourge of gender-based violence. “Fifty-seven of the department’s Regional Courts are being upgraded to operate as dedicated Sexual Offences courts during the 2013/2014 financial year. We believe that these sexual offences courts will help address the growing challenge of sexual offences in the country, particularly against vulnerable groups.”

The Minister also pleaded with law teachers to avail themselves to preside in the courts in our country to complement the decreasing number of presiding officers that are drawn from the attorneys’ and advocates’ profession. These services are normally rendered by the Commissioners pro bono as part of an endeavour to bring justice to all the people, including the poor.

A challenge that the UFS could help resolve,is the transformation of the legal profession. “We need to increase the number of Law students and in turn increase the number of attorneys and advocates in the pool from which we derive candidate judges,” Mr Radebe said.

The Legal Practice Bill and the transformation of the State Legal Service are the most important initiatives underway by which the Institutions of Higher Learning will make a contribution. “The Bill seeks to establish a single regulatory structure, which will be responsible for setting the norms and standards for all legal practitioners. Members of the public, as primary beneficiaries of the legal profession, will also be represented in this structure. Other important objectives of the Bill are the removal of barriers of entry to the profession for young law graduates who aspire to pursue a legal career, and the introduction of measures aimed at ensuring that fees chargeable for legal services are reasonable and within reach of ordinary citizens,” he said.

The Minister concluded: “Our courts must reflect both the race and gender demographics of our country and so must the university communities in their various capacities as a microcosm of the society we seek to build.”
