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…
An Excessive Core Collapse in Nbody Cosmological simulations
Weike Xiao, Xufen Wu
The particle mass used in cosmology N-body simulations is close to , which is about times larger than the GeV scale expected in particle physics. However…
A Cosmology-Independent Calibration of Gamma-Ray Burst Luminosity Relations and the Hubble Diagram
Nan Liang, Wei Ke Xiao, Yuan Liu +1
An important concern in the application of gamma-ray bursts (GRBs) to cosmology is that the calibration of GRB luminosity/energy relations depends on the cosmological model, due to…
Detecting a physical difference between the CDM halos in simulation and in nature
Weike Xiao, Chang Peng, Xianfeng Ye +1
Numerical simulation is an important tool to help us understand the process of structure formation in the universe. However many simulation results of cold dark matter (CDM) halos…
