Abstract:
We have entered a new era of powerful instruments, enabling high-precision cosmological observations. The Wide-Field-Imager (WFI) at the ESO/MPG
2.2-m telescope is a precursor of them since its field of view is large and of superb image quality. We employed the WFI to compile the Garching-Bonn Deep Survey
(GaBoDS), where most of the high-quality images are obtained
via data mining the ESO archive. This large virtual survey is used to determine some of the statistical properties of
the Universe utilising weak gravitational lensing.
