A three dimensional object point process for detection of cosmic filaments

TL;DR

This paper introduces a novel 3D object point process method for detecting cosmic filaments in large-scale structure data, demonstrated on the 2dF Galaxy Redshift Survey.

Contribution

It presents a new application of object point processes for automatically identifying cosmic filaments in redshift catalogues.

Findings

Successful delineation of cosmic filaments in the 2dF survey

Method demonstrates feasibility for large-scale structure analysis

Provides a new tool for cosmological data interpretation

Abstract

We propose to apply an object point process to automatically delineate filaments of the large-scale structure in redshift catalogues. We illustrate the feasibility of the idea on an example of the recent 2dF Galaxy Redshift Survey, describe the procedure, and characterise the results.
