Description
The extreme and often varying nature of Active Galactic Nuclei can be investigated by observations of very-high-energy gamma rays. Studying their long-term behaviour and flaring episodes requires the ability to take continuous observations over large spans of time. The Cherenkov Telescope Ring is thus a project to establish a worldwide network of Imaging Air Cherenkov Telescopes (IACT). This will allow for long-term continuous observations and 24-hour follow-up availability in case of transient events. Establishing a site in Australia will be crucial to obtain a full-sky coverage. The performance of an IACT site depends on the number of telescopes, their layout, and their height. To investigate possibilities for an Australian site, simulations need to be made and analysed.
In this talk the concept and science cases of a Cherenkov Telescope Ring will be briefly introduced, and preliminary comparisons of simulated site performance will be presented.
