- Description: This mini-thesis serves as a supporting document for my Master of Fine Art (MFA) exhibition, ‘Twee Kante van ‘n Storie’. The exhibition explores my culture and experiences as a ‘Coloured’ woman in Makhanda through storytelling. I use the term ‘Coloured’ with quotation marks to remain respectful to those who do not wish to reclaim the term. My minithesis analyses how video games as artworks can be a mode of storytelling and can encourage sociocultural awareness. In my research, I use storytelling as a tool and autoethnography as a methodology to both discuss and influence my practice. For my MFA installation, I have created a digital interactive website that uses the same language as a video game. Throughout my process, I have used two video games, That Dragon Cancer and Boet Fighter, as case studies, in order to help the building and creation of my autoethnographic art video game. My art video game explores my experiences of my culture and living in a small town. Through the creation of four fictionalised characters, which are loosely based on true life experiences and first-hand observations, I can reveal and unpack cultural experiences and biases that I have observed over the years. Each character in the game grapples with one of three prominent themes; stereotypes, ‘swagger’ and texturism. Furthermore, through using autoethnography as a methodology and the researcher as the phenomenon (Ellis, 2004: 45). This study contributes to the gap in ‘Coloured’ cultural diversities that exist outside the lens of the Western Cape experience. This is a perspective not commonly found within academia. , Thesis (MFA) -- Faculty of Humanities, Fine Art, 2023

- Description: Galaxy clusters are the largest, gravitationally-bound structures in the Universe, formed through the hierarchical merger of smaller structures. The most accepted view is that the merging process injects energy into the intracluster medium (ICM) and re-accelerates pre-existing particles and compresses magnetic fields, generating, eventually, synchrotron emission. Such radio emission appears as radio halos, i.e. central Mpc-size diffuse structures, mostly visible in merging or unrelaxed clusters and with a spatial correspondence with the thermal gas component of the ICM. Observations have probed radio halo properties mostly for clusters withM500 > 6×1014 M⊙ at intermediate redshifts (0.3 < z < 0.4), providing support to their connection between mergers, which provide the necessary energy to re-accelerate particles via turbulence. Probing the redshift evolution of radio halos is an important test of the turbulent re-acceleration scenario, as fewer halos are expected at high redshift, given the same mass interval. In this thesis, we present MeerKAT observations at 1.28 GHz of three high-redshift (PSZ2G254.08- 58.45, PSZ2G255.60-46.18 and PSZ2G277.76-51.74, in the 0.42 ≲ z ≲ 0.46 range) clusters, with masses M500 ≳ 6.2 × 1014 M⊙, selected for their disturbed dynamical state – inferred from existing X-ray observations. Our observations reached rms noise values between 20 and 23.5 μJy beam−1, with ∼ 4′′ angular resolution. No evidence of diffuse emission is found at ii full resolution. Low-resolution (∼ 30′′) images achieved rms noise levels of 30-50 μJy beam−1, amongst the deepest observations of high-redshift targets. One radio halo was detected in the least massive cluster PSZ2G254.08-58.45 extending over ∼ 500 kpc, with a 1.20 } 0.08 mJy integrated flux density. We placed a ∼1 mJy upper limit at 95% confidence level on the radio halo flux density for the other two targets. The radio-halo detection is consistent with the recent P1.4 GHz − M500 correlation from Cuciti et al. (2021b), while the upper limit on PSZ2G255.60-46.18 is consistent with being on the correlation. On the other hand, the upper limit on PSZ2G277.76-51.74 places the radio halo well below the correlation. Recently a 1.5 GHz survey (Giovannini et al., 2020) detected a slightly higher fraction of radio halos in clusters in the same redshift range, with power and size typically higher than what we found in our observations. Both observations are, however, not inconsistent with each other. Our results, although with limited statistics, do not disfavour the current scenario of radiohalo formation based on the turbulent re-acceleration model. , Thesis (MSc) -- Faculty of Science, Physics and Electronics, 2023
