The Multiscale Morphology Filter: Identifying and Extracting Spatial Patterns in the Galaxy Distribution

arXiv:0705.2072 · doi:10.1051/0004-6361:20077880

Abstract

We present here a new method, MMF, for automatically segmenting cosmic structure into its basic components: clusters, filaments, and walls. Importantly, the segmentation is scale independent, so all structures are identified without prejudice as to their size or shape. The method is ideally suited for extracting catalogues of clusters, walls, and filaments from samples of galaxies in redshift surveys or from particles in cosmological N-body simulations: it makes no prior assumptions about the scale or shape of the structures.}
