Merging dark matter halos in 3D
A merger tree in 3D: the spheres correspond to positions and sizes of dark matter halos that merge from redshift z~5 to z=0 to the most massive halo in the MDR1 cosmological simulation. Colors represent the different timesteps; the big red sphere in the center corresponds to the final halo’s position and size. The grey box just helps to guide the eye and has a side length of 40 Mpc/h.
All the information can be extracted directly from the public CosmoSim database.
