DESCRIPTION:I revisit the claim of Dark Energy detection after stacking CM
 B data on the angular position of voids and superclusters in Sloan Data. I
  examine the theoretically expected amplitude for the ISW-induced signal a
 nd explore its scale dependence. I next confront these predictions with re
 sults obtained from real WMAP data\, and evaluate the degree of agreement 
 and the possible presence of contaminants. In a more general context\, I a
 ddress the possibility of unveiling the signature of Dark Energy on the CM
 B by looking at isolated regions on the sky hosting high-threshold project
 ed under/over-densities: this constitutes a novel approach since it is les
 s sensitive to large angle systematics commonly present in large scale str
 ucture surveys.\n\nhttps://indico.ific.uv.es/event/1813/
