Accurate estimators of power spectra in N-body simulations
Stephane Colombi, Andrew H. Jaffe, Dmitri Novikov +1
abridged] A method to rapidly estimate the Fourier power spectrum of a point distribution is presented. This method relies on a Taylor expansion of the trigonometric functions. It…
The three dimensional skeleton: tracing the filamentary structure of the universe
T. Sousbie, C. Pichon, S. Colombi +2
The skeleton formalism aims at extracting and quantifying the filamentary structure of the universe is generalized to 3D density fields; a numerical method for computating a local…
The 3D skeleton of the SDSS
Thierry Sousbie, Christophe Pichon, Hélène Courtois +2
The length of the three-dimensional filaments observed in the fourth public data-release of the SDSS is measured using the {\em local skeleton} method. It consists in defining the…
