  text: "The cosmic microwave background (CMB) has provided a precise template for
    features in the linear power spectrum: the matter-radiation turnover, sound horizon
    drop, and acoustic oscillations. In a two-dimensional power spectrum in redshift
    and angular space, the features appear as distorted rings, and yield simultaneous,
    purely geometric, measures of the Hubble parameter \U0001D43B⁡(\U0001D467) and
    angular diameter distance \U0001D437\U0001D434⁡(\U0001D467) via an absolute version
    of the Alcock-Paczynski test. Employing a simple Fisher matrix tool, we explore
    how future surveys can exploit these rings of power for dark energy studies. High-z
    CMB determinations of H and \U0001D437\U0001D434 are best complemented at moderate
    to low redshift (\U0001D467≲0.5) with a population of objects that are at least
    as abundant as clusters of galaxies. We find that a sample similar to that of
    the ongoing SDSS luminous red galaxy survey can achieve statistical errors at
    the ∼5% level for \U0001D437\U0001D434⁡(\U0001D467) and \U0001D43B⁡(\U0001D467)
    in several redshift bins. This, in turn, implies errors of \U0001D70E⁡(\U0001D464)=0.03–0.05
    for a constant dark energy equation of state in a flat universe. Deep galaxy cluster
    surveys such as the planned South Pole Telescope survey can extend this test out
    to \U0001D467∼1 or as far as redshift follow-up is available. We find that the
    expected constraints are at the \U0001D70E⁡(\U0001D464)=0.04–0.08 level, comparable
    to those of galaxies and complementary in redshift coverage."
