Abstract
The Cherenkov Telescope Array (CTA) observatory is the next generation of ground-based imaging
atmospheric Cherenkov telescopes (IACTs). Building on the strengths of current IACTs, CTA
is designed to achieve an order of magnitude improvement in sensitivity, with unprecedented
angular and energy resolution. CTA will also increase the energy reach of IACTs, observing
photons in the energy range from 20 GeV to beyond 100 TeV. These advances in performance will
see CTA heralding in a new era for high-energy astrophysics, with the emphasis shifting from
source discovery, to population studies and precision measurements. In this talk we discuss CTA’s
ability to conduct source population studies of W-ray bright active galactic nuclei and how this
ability will enhance our understanding on the redshift evolution of this dominant W-ray source
class.
