Probing topological relation between high density and low density region of 2MASS with hexagon cells
Yongfeng Wu, Weike Xiao
We introduce a new 2-D hexagon technique to probe the topological structure of the universe, in which we map regions of the sky with high and low galaxy densities onto a 2-D lattic…
Nearest neighbor vector analysis of sdss dr5 galaxy distribution
Yongfeng Wu, Weike Xiao, Rongjun Mu +2
We present the Nearest Neighbor Distance (NND) analysis of SDSS DR5 galaxies. We give NND results for observed, mock and random sample, and discuss the differences. We find that th…
SZ effect or Not? - Detecting most galaxy clusters' main foreground effect
Weike Xiao, Chen Chen, Bin Zhang +2
Galaxy clusters are the most massive objects in the Universe and comprise a high-temperature intracluster medium of about 10^7 K, believed to offer a main foreground effect for cos…
Three-Dimensional Filamentation Analysis of SDSS DR5 Survey
Yongfeng Wu, David J. Batuski, Andre Khalil
We introduce a new method to calculate the multi-scale 3D filamentation of SDSS DR5 galaxy clusters and also applied it to N-body simulations. We compared the filamentation of the…
