Effects of the size of cosmological N-body simulations on physical quantities II-. Halo formation and destruction rate

Abstract

In this study we show how errors due to finite box size affect formation and destruction rate for haloes in cosmological N-body simulations. In an earlier study we gave an analytic prescription of finding the corrections in the mass function. Following the same approach, in this paper we give analytical expressions for corrections in the formation rate, destruction rate and the rate of change in comoving number density, and compute their expected values for the power law ($n=-2$) and LCDM models.
