A reassessment of the evidence of the Integrated Sachs–Wolfe effect through the WMAP–NVSS correlation
We reassess the estimate of the cross-correlation of the spatial distribution of the NRAO VLA Sky Survey (NVSS) radio sources with that of cosmic microwave background anisotropies from the Wilkinson Microwave Anisotropy Probe (WMAP). This reanalysis is motivated by the fact that most previous studies adopted a redshift distribution of …
