Scientific paper

We present a brief introduction to dark energy in flat universes and the possibility to measure it with a combination of optical/infrared and millimeter surveys. The cross-correlation of galaxy maps with Cosmic Microwave Background radiation (CMB) temperature anisotropies can be used to constrain the rate of linear growth of structures and therefore the cosmic parameters. We present a combination of such cross-correlation measurements and show that, under certain assumptions, these data reveal the amount of dark energy in the universe.
