ATHENA Overview

Slice of a dark matter halo from an N-body Simulation. The left panel depicts a 2D projection centered on the halo. The middle and right panels then display the infalling and orbiting populations as described by SPARTA. The black circle indicates the traditional R200m halo radius.

Scientific plots can be confusing, Dark Matter Halo has a breakdown of what the plot is showing and what the key takeaways are!
