Figure 26: Top: Measurement of the cross-correlation functions between six different galaxy data sets
and the CMB, reproduced from [166]. The curves show the theoretical predictions for the ISW-galaxy
correlations at each redshift for the LCDM model (black, dashed) and the three nDGP models, which
describe the region of the geometry test from Figure 25. (From [167].) Bottom: Theoretical
predictions for a family of theories compared with the ISW data [166] measuring the angular
CCF between the CMB and six galaxy catalogues. The model with is equivalent to LCDM,
while increasing departures from GR produce negative cross-correlations. (From [165].)
