Free Cosmic Density Bispectrum on Small Scales
Ricardo Waibel, Sara Konrad, Matthias Bartelmann
We study the asymptotic behaviour of the free, cold-dark matter density fluctuation bispectrum in the limit of small scales. From an initially Gaussian random field, we draw phase-…

Gravitational Turbulence: the Small-Scale Limit of the Cold-Dark-Matter Power Spectrum
Yonadav Barry Ginat, Michael L. Nastac, Robert J. Ewart +3
The matter power spectrum, , is one of the fundamental quantities in the study of large-scale structure in cosmology. Here, we study its small-scale asymptotic limit, and sho…
