Observations of variability of TeV gamma-ray blazars
The boom in ground-based gamma-ray astronomy since the beginning of the 21st century has enabled a new probe of the universe using very-high-energy photons. The Very Energetic Radiation Imaging Telescope Array System (VERITAS) is an array of four 12-m imaging Cherenkov telescopes that is sensitive …

The analysis and interpretation of VHE (Eg > 1 TeV gamma ray measurements
It is well known that Very High Energy Gamma kay Astronomy (VHEGRA) is facing a dilemma in the sense that all reported sources are very weak emitters of VHE 1-rays. The status of most sources are also questionable on statistical grounds, while very few sources have been confirmed. This dilemma can …

Studies of TeV Gamma-Ray Sources in the Hydrogen-Alpha Optical Line
… using different electromagnetic wavebands such X-rays, gamma-rays, and radio wavelengths. Since then multi-wavelength studies of sources have started to explain their physical properties. The links between the TeV (1012 eV) gamma-ray emission of HESS J1825-137 and an optical supernova remnant …

The Search For Pulsar Wind Nebulae in the Very High Energy Gamma-ray Regime
… the development of pulsar wind nebulae in the TeV regime and in doing so uncover more sources which have as yet not been observed at these wavelengths. It is found that the extent of pulsar wind nebula in the TeV gamma-ray increases with its age while no developmental relationship is seen …

Observational Properties of Gigaelectronvolt-Teraelectronvolt Blazars and the Study of the Teraelectronvolt Blazar RBS 0413 with VERITAS
… is referred to as the very-high-energy (VHE or TeV, E > 0.1 TeV) regime. At the time of this writing, more than half a hundred blazars have been detected to emit TeV gamma rays, representing the high energy extreme of these objects and constituting a population of its own. Most of these TeV …

Pulsar wind nebulae at high energies
Pulsar wind nebulae (PWNe) are the most abundant TeV gamma-ray emitters in the Milky Way. The radiative emission of these objects is powered by fast-rotating pulsars, which donate parts of their rotational energy into winds of relativistic particles. This thesis presents an in-depth study of the …

Towards Gamma-Ray Telescopes in Australia
Recent decades have seen the rise of the field of gamma-ray astronomy, probing the most extreme environments in our Universe. The upcoming Cherenkov Telescope Array Observatory (CTAO), alongside H.E.S.S. in Namibia, are Imaging Air Cherenkov Telescopes (IACTs) that will cover roughly two thirds of …
