Snapshot from a Cosmological Simulation (IMAGE) Ohio Supercomputer Center Caption Snapshots from cosmological simulations (left) performed on Ohio Supercomputer Center systems and a plot of the clustering of dark matter on different scales (right). [For animation, see: http://www.physics.ohio-state.edu/~orban/xi_anim_vhighres.gif] Orban and Weinberg are studying the evolution of the Baryon Acoustic Oscillations standard ruler using a new cosmological model that simplifies the non-linear dynamics that affect the BAO bump feature.
