The Astrophysical sciences are witnessing a flood of observations from ground and spaced based surveys. With access to data spanning X-ray through to radio wavelengths we are now able to extract sources from any region of the sky and measure their properties across the full range of
the electromagnetic spectrum. Individually, each of these huge data sets are leading to major advances in our understanding of the processes that drive the formation and evolution of the Universe. It is, however, only when we combine these data - by collating observations from several
different surveys - that their full scientific potential will finally be realized. In this talk I will discuss the computational challenges of these new multi-frequency data sets by focusing on how they can be used to detect the imprint of dark energy on the growth of structure in the
universe. I will present results that challenge our current views on the clustering of galaxies and will show that the surveys we have access to today represent just the initial steps in understanding the evolution of our universe.
