The CTA (Cherenkov Telescope Array) is a transformational next step in
ground-based TeV (10^12 electron-volt) gamma-ray astronomy. It will
utilise the successful methods employed by H.E.S.S. and others in the
field via an array of about 100 imaging Cherenkov telescopes in the
Southerm Hemisphere located at Paranal, Chile, with a smaller array
in the Northern Hemisphere at La Palma, Canary Islands.
The CTA will cover a wide energy range, from about 20 GeV to well over 100 TeV.
A two day workshop is being held at the University of Sydney this week to
disuss Australia's role in CTA and linkages with Australian activities in
other areas of astronomy. The connections with radio astronomy will be explored
in talks on the ASKAP EMU and GASKAP surveys, and with results at mm wavelengths
from the Mopra telescope.
