Correlation of CMB with large-scale structure: I. ISW Tomography and Cosmological Implications
Shirley Ho, Christopher M. Hirata, Nikhil Padmanabhan +2
We cross-correlate large scale structure (LSS) observations from a number of surveys with CMB anisotropies from WMAP to investigate the Integrated Sachs-Wolfe (ISW) effect as a fun…
