The Cold Spot as a Large Void: Rees-Sciama effect on CMB Power Spectrum and Bispectrum
The detection of a "Cold Spot" in the CMB sky could be explained by the presence of an anomalously large spherical underdense region (with radius of a few hundreds Mpc/h) located between us and the Last Scattering Surface. Modeling such an underdensity with an LTB metric, we investigate wh...
