The Scaling Relations of Galaxy Clusters and Their Dark Matter Halos
The Scaling Relations of Galaxy Clusters and Their Dark Matter Halos
Like early-type galaxies, nearby galaxy clusters also define fundamental plane, luminosity-radius, and luminosity-velocity dispersion relations, whose physical origins are still unclear. By means of high-resolution N-body simulations of massive dark matter halos in a ΛCDM (Λ cold dark matter) cosmology, we find that scaling relations similar to those observed for …
