Revisiting the ISW evidence
Crittenden, Robert (ICG, Portsmouth )

The integrated Sachs-Wolfe effect provides an important independent constraint on models of dark energy, and is particularly useful in constraining modified gravity. Recently, the detections of the ISW cross correlations have come under question from a number of groups. I will discuss these criticisms, and give an update with the most recent large scale structure surveys. If time allows, I will also discuss the issue of how ISW information relates to redshift space distortion measurements, a probe which is similarly sensitive to the time derivative of the growth function.
