Understanding the cosmic web

Understand

We investigate the characteristics and the time evolution of the cosmic web from redshift, z=2, to present time, within the framework of the NEXUS+ algorithm.

• This necessitates the introduction of new analysis tools optimally suited to describe the very intricate and hierarchical pattern that is the cosmic web.
• In particular, we characterize filaments (walls) in terms of their linear (surface) mass density.
• This is very good in capturing the evolution of these structures.
