Toward accurate measurement of property-dependent galaxy clustering: II. Tests of the smoothed density-corrected method
Lei Yang, Zhigang Li
We present a smoothed density-corrected technique for building a random catalog for property-dependent galaxy clustering estimation. This approach is essentially base…
Toward accurate measurement of property-dependent galaxy clustering I. Comparison of the Vmax method and the "shuffled" method
Lei Yang, Yipeng Jing, Zhigang Li +1
Galaxy clustering provides insightful clues to our understanding of galaxy formation and evolution, as well as the universe. The redshift assignment for the random sample is one of…
Cosmological parameter estimation from large-scale structure deep learning
Shuyang Pan, Miaoxin Liu, Jaime Forero-Romero +4
We propose a light-weight deep convolutional neural network (CNN) to estimate the cosmological parameters from simulated 3-dimensional dark matter distributions with high accuracy.…
BSG alignment of SDSS galaxy groups
Zhigang Li, Yougang Wang, Xiaohu Yang +3
We study the alignment signal between the distribution of brightest satellite galaxies (BSGs) and the major axis of their host groups using SDSS group catalog constructed by Yang e…
