    Results of the simulations, carried out by Durham University's world-leading Institute for Computational Cosmology (ICC), tell researchers how to measure dark energy -- a repulsive force that counteracts gravity.

    What are these sound waves?

    The simulations, which took 11 days to run on Durham's unique Cosmology Machine (COSMA) computer, looked at tiny ripples in the distribution of matter in the Universe made by sound waves a few hundred thousand years after the Big Bang.

    I think the "Findings are published January 11 in the Monthly Notices of the Royal Astronomical Society" refers to this paper: The detectability of baryonic acoustic oscillations in future galaxy surveys.

    Abstract:
    The 'sound waves' referred to are baryon acoustic oscillations (BAO) ... an exciting, relatively new, field in observational cosmology.
