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.”

You touch a woman, you strike a rock
2004-11-02

Prof. Engela Pretorius van die Departement Sosiologie in die Fakulteit Geesteswetenskappe by die Universiteit van die Vrystaat het die kwessie omtrent feminisme aangespreek tydens haar intreerede met die onderwerp, You touch a woman, you strike a rock: Feminism(s) and emancipation in South Africa .

Prof. Pretorius het gesê: “Die geskiedenis van feminisme oor die algemeen kan in drie fases verdeel word, waarna verwys word as golwe. Eerste-golf-feminisme (19de eeu) het die fokus geplaas op die beskerming van vroueregte in die openbare terrein, spesifiek die reg om te stem, die reg tot onderrig en die reg om middelklas beroepe en professies te betreë.

Vroeë tweede-golf-feminisme word onthou vir hoe dit moederskap geteoretiseer het as synde ‘n onderdrukkende instelling. Slagspreuke van die 1970s was die persoonlike is polities en susterskap is magtig. Prof. Pretorius sê beide slagspreuke bevestig die idee dat vroue universeel onderdruk en uitgebuit word en slegs deur erkenning van dié situasie kan vroue die strukture wat hul onderdruk verander.

‘n Belangrike aspek van die derde golf van die feminisme-teorie is post-moderne feminisme wat diversiteit en verskille onderstreep. Die poging van hierdie feministe is afgestem op alle vorme van onderdrukking. Vroue van kleur het ook hul ontevredenheid uitgespreek gedurende die derde-golf-feminisme. Die feminisme van vroue van kleur word gekenmerk deur verskeie kwessies en talryke intellektuele standpuntinnames wat neerslaga vind in verskillende terme, soos Afrika feminisme of ‘womanism, sê prof. Pretorius.

Afrika-feminisme dui protes aan teen die wit/westerse geskiedenis en die wit/westerse dominansie binne feminisme. Afrika-vroue het besef dat hul onderdrukking verskillend is van dié van wit vroue en daarom is ‘n ander proses van bevryding nodig. Die Westerse feministiese praktyk om swart vroue by die bestaande feministiese ontologie te voeg, is nie voldoende nie omdat hul unieke ondervindings van slawerny, kolonialisme, onderdrukking deur mans en armoede nie uitgedruk word nie.

‘Womanism’ het tot stand gekom as gevolg van ‘n eksplisiete rassekritiek teen feminisme. Dit is ten gunste van die positiewe uitbeelding van swart mense. Dit word gekenmerk deur kulturele kontekstualisasie, die sentraliteit van die gesin en die belangrikheid daarvan om mans in te sluit.

Die geskiedenis van vroue in Suid-Afrika is verwant aan hul geskiedenis van onderdrukking as gevolg van patriargie. Vroue van verskillende rasse, kulture en klasse het patriargie op verskillende wyses in en variërende mate van erns ervaar. Onder voor-koloniale patriargie het vroue min sê gehad oor huwelikskeuses omdat mans dié besluite gedomineer het.

Die Nederlandse en Britse patriargale erfenis het neerslag gevind in die ideologie van die volksmoeder. Onderwyl dit veral manlike skrywers was wat die beeld van die vrou as versorger en tuisteskepper bevorder het, het vroue self ook hieraan ‘n aandeel gehad, sodat die volksmoeder volwaardig deel geword het van die Afrikaner nasionalistiese mitologie. Alhoewel middel- en werkersklas vroue met dié beeld geïdentifiseer het, het nie alle Afrikaanse vroue die ideologie aanvaar nie.

Onder die Victoriaanse erfenis was Britse vroue beperk to die private eerder as die openbare lewe. Die skeefgetrekte onderrigsisteem wat vroue in huishoudelike loopbane gekanaliseer het, die mag van mans oor hul vroue se eiendom en ‘n tekort aan toegang tot mag en geld het verseker dat vroue by die huis gebly het.

Wit Engelssprekende-vroue het die grootste geleentheid gehad om patriargie uit te daag vanweë hul toegang tot onderwys en die blootstelling aan liberale waardes, sê prof. Pretorius. Liberale vroue soos Helen Joseph en Helen Suzman het ‘n belangrike rol gespeel om in 1930 stemreg vir wit vroue in Suid-Afrika te verseker en het voortgegaan om ‘n rol te speel in die bevryding van swart vroue gedurende die vryheidstryd.

Die feminisme wat onder swart vroue ontwikkel het, was ‘n erkenning van die gemeenskaplike stryd met swart mans om die verwydering van die juk van eksterne onderdrukking en eksploitasie. Swart vroue in aktiewe en onafhanlike politiese rolle het tegelykertyd mans se aannames omtrent hul meerderwaardigheid asook die rassewette van die staat uitgedaag. Daarom kan ons sê dat die feminisme wat hier ontwikkel het, te voorskyn gekom het as gevolg van vroue se betrokkenheid by en toewyding tot nasionale bevryding, sê prof. Pretorius.

Institusionalisering is nie herlei tot magsvoordele nie, want gelykheid is nie in beleidsprogramme geïnkorporeer nie. Die hervestiging van sleutel aktiviste van die vrouebeweging in die regering het die stryd om genderbillikheid verander na ‘n projek wat deur die regering gelei word, sê prof. Pretorius. Ongelukkig word terreine van verandering buite die grense van die regering verwaarloos. Dit kan slegs aangespreek word deur ‘n aktiewe en feministiese stem in die burgerlike samelewing.

“Dit is my oortuiging dat formele instellings vir vroue binne die staat oor die lang termyn slegs effektief kan wees indien daar ‘n effektiewe feministiese vroue-beweging buite die staat in stand gehou word wat die grondslag waarop sosiale beleid gevorm word, kan uitdaag en bevraagteken. Daarom, A luta continua (die stryd duur voort),” sê prof. Pretorius.
