New leaves of the tree: percolation analysis for cosmic web with discrete points
Jiajun Zhang, Dalong Cheng, Ming-Chung Chu
Percolation analysis has long been used to quantify the connectivity of the cosmic web. Most of the previous work is based on density fields on grids. By smoothing into fields, we…
Measurement of Redshift Space Power Spectrum for BOSS galaxies and the Growth Rate at redshift 0.57
Zhigang Li, Y. P. Jing, Pengjie Zhang +1
We present a measurement of two-dimensional (2D) redshift-space power spectrum for the Baryon Oscillation Spectroscopic Survey (BOSS) Data Release 11 CMASS galaxies in the North Ga…
Cosmological Structure Formation in Decaying Dark Matter Models
Dalong Cheng, M. -C. Chu, Jiayu Tang
The standard cold dark matter (CDM) model predicts too many and too dense small structures. We consider an alternative model that the dark matter undergoes two-body decays with cos…
Angular momentum - mass relation for dark matter haloes
Shihong Liao, Dalong Cheng, M. -C. Chu +1
We study the empirical relation between an astronomical object's angular momentum and mass , , the relation, using N-body simulations. In particular, we invest…
