Two-point Correlation Function and Power Spectrum at Very Large Scales

  • Z.-G. Deng (a1) and X.-Y. Xia (a2)

Abstract

Subsamples of galaxies with different morphological types have been sorted out from Stromlo-APM redshift survey. Two-point correlation function for each subsample has been calculated. The two-point correlation functions for all subsamples show very large scale fluctuation. We show that the two-point correlation function with fluctuation could be fitted by a modified power spectrum with power excess at wave number comparable to the scale of the fluctuation.
