On the equivalence between galaxy angular correlation function and power spectrum in constraining primordial non-Gaussianity
Scale cuts break the equivalence between the galaxy angular power spectrum and the angular correlation function for primordial non-Gaussianity, with the correlation function retaining fNL information on surprisingly small angular scales.
