CARAD: Computer-aided Analysis of Radio Astronomy Data
Radio astronomy studies celestial objects by detecting their radio frequency emissions, enabling observation of phenomena invisible at other wavelengths. Next-generation telescopes generate unprecedented data volumes that challenge traditional analytical approaches. Manual inspection and classical …

Fast online predictive compression of radio astronomy data
… Africa and Australia, which will produce data at rates up to 1 Petabyte every 20 seconds. The compression technique being investigated is based on predictive compression, which has proven successful at achieving high-speed compression in previous research. Several different predictive …

Assessing GridSim for modeling the global distribution of next-generation astronomy data
The transfer of big data between geographic locations incurs various costs that are better managed when computing resources are used efficiently. Measuring the energy used by a computing facility is a mechanism for managing computational efficiency because the energy provided to the facility can be …

VRDAV is: remote visualisation of astronomy data with a standalone virtual reality device
… explores the challenges of visualising vast astronomy data cubes using a virtual reality environment, addressing the ever-increasing volume of data collected by radio astronomy instruments. As the amount of data grows year after year—ranging from terabytes to petabytes—radio astronomy …

South African Astronomical Observatory data archiving for multi-wavelength astronomy research
… investigates the best practices for creating a data archive system that can store optical and radio astronomy data as well as interact with other astronomy archives. Archives are built and maintained by staff that specialise in big data storage, information security, database administration, and …

The G332 Molecular Cloud
… the velocity information from [HI] and 13CO data. The analysis of the CO and [CI] emission performed in this work has taken advantage of a new approach to radio data visualisation, realised through the use of Virtual Reality (VR) and Augmented Reality (AR) techniques. These visualisation …

Towards Generalized Characterization of Exoplanet Atmospheres with Transit Spectroscopy
… diverse planet population and higher fidelity data necessarily demand more flexible, complex, and generalized modeling frameworks. In this thesis, we present our work on atmospheric retrievals of exoplanets, focusing on investigating the robustness of the model assumptions inevitably employed …

Pulsar wind nebulae at high energies
… is introduced and compared to the available data. In particular, this work presents two exceptional PWNe which protrude from the rest of the population, namely the Crab Nebula and N 157B. Both objects are driven by pulsars with extremely high rotational energy loss rates. Accordingly, they …
