Title |
Wiener-Hermite Expansion applied for non-linear matter power spectrum | |||||
| Co-authors | ||||||||
|
Abstract |
New approximation method(Wiener-Hermite expansion) is applied for the non-linear evolution of Large-Scale Structure, and an approximated matter power spectrum in full order of expansion is obtained. The power spectrum agrees with N-body result within 2% accuracy in a wide range of the wavenumber k=0.1~0.5 h/Mpc at z=0.5-3. A merit of our method is that the computaional time is very short of the order og a few second. |
