Itasca Simulated Clusters project

A collaborative project to study the evolution of shocks and turbulence in the gas of cluster of galaxies, using highly resolved simulations.

THE CODE - ENZO

We used the cosmological grid code ENZO (v.2.1)   with tailored mesh refinement to increase the resolution everywhere within the cluster volume.
  • Each simulation start from a volume of 643 Mpc3 simulated with 400cells.
  • The innermost 6.43 Mpcis further refined 2times, down to a fixed resolution of 20kpc.
  • for the moment, we only used non-radiative runs

THE SIMULATIONS

We ran on the ITASCA cluster hosted by the University of Minnesota.
To produce our sample, we used approximately ~260 000 core hours (~13 000 hours per cluster).

THE CLUSTER CATALOG

  • The catalog presently consists of 20 clusters with a mass range centred at ~1014  Msol.
  • For most objects, we saved ~200 timesteps at full resolution, to access their dynamical evolution in detail.

Results and data products


Talks

We give here a quick access to our results, in the form of scientific visualisation (cool ones!), papers and talks 

Movies

We have plenty of 3D movies showing the complex evolution of the gas in clusters, produced using   volume ray casting .
