Here we provide a small 128^3 particle dataset for developing initial visualization methods and interfaces for the IEEE SciVis 2015 Contest. More information can be found here: http://darksky.slac.stanford.edu/scivis2015.
Feel free to directly browse the data here. The full dataset can be downloaded as a tarball with "curl -O http://darksky.slac.stanford.edu/scivis2015/data/ds14_scivis_0128.tar".
Halo catalogs can be browsed at ./ds14_scivis_0128/rockstar (we use the Rockstar halo finder), and merger trees can be found in ./ds14_scivis_0128/rockstar/hlists and ./ds14_scivis_0128/rockstar/trees. More information about the halo catalog and merger trees can be found at https://bitbucket.org/gfcstanford/rockstar and https://bitbucket.org/pbehroozi/consistent-trees.
