摘要：

We present a map of the cosmic microwave background (CMB) anisotropies induced by the late integrated Sachs-Wolfe effect. The map is constructed by combining the information of the Wilkinson Microwave Anisotropy Probe 7-yr CMB data and the NRAO VLA Sky Survey (NVSS) through a linear filter. This combination improves the quality of the map that would be obtained using information only from the large-scale structure data. In order to apply the filter, a given cosmological model needs to be assumed. In particular, we consider the standard Lambda cold dark matter model. As a test of consistency, we show that the reconstructed map is in agreement with the assumed model, which is also favoured against a scenario where no correlation between the CMB and NVSS catalogue is considered.
