Non-linear nature of Einstein equation introduces genuine relativistic higher order corrections to the usual Newtonian fluid equations describing the evolution of cosmological perturbations.
Cosmology in One Dimension:Fractal Geometry, Power Spectra and Correlation
One Dimension Fractal Geometry Power Spectra

Concentrations of matter, such as galaxies and galactic clusters, originated as very small density fluctuations in the early universe. The existence of galaxy clusters and super-clusters suggests that...
Bayesian modeling and significant features exploration in wavelet power spectra
Bayesian modeling significant features exploration wavelet power spectra
2009/11/2
This study proposes and justifies a Bayesian approach to modeling wavelet coefficients and finding statistically significant features in wavelet power spectra. The approach utilizes ideas elaborated i...
