Detecting filamentary pattern in the cosmic web: a catalogue of filaments for the SDSS

Understand

The main feature of the spatial large-scale galaxy distribution is its intricate network of galaxy filaments.

• This network is spanned by the galaxy locations that can be interpreted as a three-dimensional point distribution.
• The global properties of the point process can be measured by different statistical methods, which, however, do not describe directly the structure elements.
• The morphology of the large scale structure, on the other hand, is an important property of the galaxy distribution.
