Formation of a very massive galaxy clusters
This movie shows the evolution of the gas during the formation of a very massive galaxy cluster from the RHAPSODY-G simulations. The gas density is shown in gray colors with the gas temperature overlaid in orange. The abundance and properties of these massive systems contain a wealth of information about the physics and cosmology of our Universe. The image is 17 Mpc/h wide, projection depth is 5 Mpc/h.

Formation of the cosmic web, dark matter streams II
This movie shows the formation of the cosmic web of dark matter from random fluctuations in the early universe. The intricate network of filaments hosts dark matter halos, the most massive of them are rendered in bright yellow hinting at the galaxies they are thought to host in the LCDM cosmological model.

Formation of the cosmic web, dark matter streams I
This movie shows the formation of the in the hierarchical LCDM structure formation scenario. The density field shown in the movie is rendered using the method presented in Kaehler, Hahn & Abel 2012 based on the Lagrangian tesselation method discussed in Abel, Hahn & Kaehler 2012.

Formation of a warm dark matter halo
This movie shows the formation of a halo in a warm dark matter cosmology. Unlike in CDM, halos here have no progenitors but form from smooth accretion of dark matter (see also my papers on WDM halo formation, Angulo, Hahn & Abel 2013 and Hahn & Paranjape 2013). The density field shown in the movie is rendered using the method presented in Kaehler, Hahn & Abel 2012 based on the Lagrangian tesselation method discussed in Abel, Hahn & Kaehler 2012.

Formation of a massive galaxy cluster in an N-body simulation
This movie shows the formation of a massive galaxy cluster in the LCDM cosmological model. The cluster forms hierarchically over time by accreting myriads of smaller clumps, of which the larger ones are expected to host galaxies.
From the RHAPSODY simulation suite, Wu, Hahn, Wechsler, Mao & Behroozi 2013.
