WebBased on a suite of state-of-the-art high-resolution N-body simulations, we revisit the so-called halofit model (Smith et al. 2003) as an accurate fitting formula for the nonlinear matter power spectrum. While the halofit model has been frequently used as a standard cosmological tool to predict the nonlinear matter power spectrum in a universe … WebDM cosmology with a cosmological constant, the so-called CDM model [e.g.,6]. Still, DM remains merely a postulate and constitutes one of the biggest puzzles in fundamental physics. Over the years, a variety of DM candidates have been proposed [see, e.g.,7]. A speci c and well-motivated particle physics candidate for DM is the axion [8{11].
