GriSPy: A Python package for Fixed-Radius Nearest Neighbors Search
Martin Chalela, Emanuel Sillero, Luis Pereyra +4
We present a new regular grid search algorithm for quick fixed-radius nearest-neighbor lookup developed in Python. This module indexes a set of k-dimensional points in a regular gr…
A comparison of cosmological filaments catalogues
Agustín Rost, Federico Stasyszyn, Luis Pereyra +1
In this work we compare three catalogues of cosmological filaments identified in the Sloan Digital Sky Survey by means of different algorithms by Tempel et al., Pereyra et al., and…
Detection and analysis of cluster-cluster filaments
Luis A. Pereyra, Mario A. Sgró, Manuel E. Merchán +2
In this work, we identify and analyse the properties of cluster-cluster filaments within a cosmological simulation assuming that they are structures connecting maxima of the densit…
