Pair Counting without Binning -- A New Approach to Correlation Functions in Clustering Statistics
Shiyu Yue, Longlong Feng, Wenjie Ju +6
This paper presents a novel perspective on correlation functions in the clustering analysis of the large-scale structure of the universe. We first recognise that pair counting in b…
