Description

The extreme and often varying nature of Active Galactic Nuclei, along with gamma-ray bursts and other transients, can be investigated with observations of very-high-energy gamma rays. Studying them requires uninterupted availability and the capacity to take continuous observations over large spans of time. The Cherenkov Telescope Ring is thus an idea to establish a worldwide network of Imaging Air Cherenkov Telescopes (IACT). This would allow for long-term continuous observations and 24-hour follow-up availability in case of transient events. Establishing an IACT site in Australia would be crucial to obtain full-sky coverage, and would be able to trigger other telescopes such as CTA to take observations of their own. The performance of an IACT site depends on factors such as its altitude, number of telescopes, the layout, and telescope design. To investigate possibilities for an Australian site simulations have been made, analysed, and compared. In this talk the concept and science cases of a Cherenkov Telescope Ring will be briefly introduced, and comparisons of simulated site performance will be presented. Lightcurves and spectrum reconstruction from simulated source observations will also be shown.
