Improving SDSS cosmological constraints through -skeleton weighted correlation functions
Fenfen Yin, Jiacheng Ding, Limin Lai +6
The -skeleton approach can be conveniently utilized to construct the cosmic web based on the spatial geometry distribution of galaxies, particularly in sparse samples. This meth…
