Density-based clustering algorithm for galaxy group/cluster identification
Published in arXiv, 2024
A new density-based clustering algorithm, sOPTICS, which outperforms the traditional Friends-of-Friends (FoF) algorithm in identifying galaxy groups and clusters by incorporating a scaling factor to account for line-of-sight positional uncertainties due to redshift space distortions.
