With the advent of very large European survey telescopes, in particular the Canada-France-Hawaii-Telescope (CFHT) (in progress) and the VLT Survey Telescope (VST), due in 2007, large-scale imaging and photometric surveys will soon yield an abundance of data containing both high-quality galaxy images and multi-wavelength information. Such large datasets put a huge demand on analysis methods. Over the last few years, such data have been exploited to study the gravitational lensed images of distant galaxies.
The distortions, caused by photons being deflected by the large-scale distribution of matter, are small and their analysis places a high demand on data, pushing both data quality and analysis techniques. The DUEL (Dark Matter with Extragalactic Lensing) research and training network proposes to exploit these data to map the distribution of Dark Matter in the Universe projected on the sky and in 3-D, using gravitationally lensed images of distant galaxies, from upcoming imaging and photometric galaxy red shift surveys, in particular the VST-KIDS survey. With this we will: (1) probe the nature of the Dark Matter from its large-scale distribution and evolution; (2) compare the Dark Matter distribution with that of the galaxies as a function of environment and cosm ic time; (3) probe the equation of state of the Dark Energy content of the Universe.
The DUEL research and training network will be vital in the development of these methods and the training of a new generation in state-of-the-art methods needed to exploit these and future sets. Since these datasets are so large, single institutes are not equipped to reduce and analyze them. DUEL will form a coherent network of observers and theoreticians required to optimally exploit these data and maintain European leader ship in Cosmology.
