Matter distribution for power spectra with broken scale invariance

To test the primordial power spectra predicted by a double inflationary model with a break of amplitude {Delta}=3 at a scale of 2{pi}/{ital k}{approx_equal}10 {ital h}{sup {minus}1} Mpc and cold dark matter (CDM) as dominant matter content, we perform particle-mesh simulations with 128{sup 3} particles on a 256{sup 3} grid. The broken scale invariance of the power spectra explains the extra power observed in the large-scale matter distribution. {ital COBE}-normalized spectra and a linear biasing with {ital b}{approx_equal}2 are shown to reproduce the reconstructed power spectra from the CfA catalog. By identifying galactic halos with a random selection of particles in overdensity regions of approximately 2 times the cell variance, we can fit the angular correlation function using both the Limber equation and creating an APM-like angular projection with the observed luminosity function. Finally, the higher order moments of the galaxy distribution are shown to fit reasonably well the observed values. {copyright} {ital 1995 The American Astronomical Society.}
