1 COMPLEX DATA VISUALIZATION 15/01/2015 CEA DSM Irfu - Daniel Pomarède - COMPLEX DATA VISUALIZATION 1
2 COMPLEX DATA VISUALIZATION a software project established in the context of the COAST «Computational Astrophysics» IRFU Program involving SAp and SEDI main component is the SDvision «Saclay Data Visualization» software developed at SEDI/LILAS lines of IDL code primary target: visualizing the complex, massive, three-dimensional data produced by numerical simulations in astrophysics benefits to other research area: observational astrophysical data other domains: accelerators, fusion plasma, nuclear physics, 15/01/2015 CEA DSM Irfu - Daniel Pomarède - COMPLEX DATA VISUALIZATION 2
3 Formation of a Milky Way-like spiral galaxy in a cosmological context (RAMSES code) The galaxy is nourished by cold gas coming from the filaments. Hot gas is injected in the environment ( supernovae feedback ). Stereo3D movie running at Musée des Confluences in Lyon (inaugurated december 19th, 2014)
