We present a global measurement of the integrated Sachs-Wolfe (ISW) effect obtained by cross correlating all relevant large-scale galaxy data sets with the cosmic microwave background radiation map provided by the Wilkinson Microwave Anisotropy Probe. With these measurements, the overall ISW signal is detected at the $\ensuremath{\sim}4.5\ensuremath{\sigma}$ level. We also examine the cosmological implications of these measurements, particularly the dark energy equation of state $w$, its sound…
