Initial Conditions:

TNG50-2 has its initial conditions available.

Download Initial Conditions (37.5 GB in one HDF5 file)

simulation.hdf5 file:

TNG50-2 has the virtual 'simulation.hdf5' container file available.

Download simulation.hdf5 File (188.6 MB)

Merger Trees:

TNG50-2 has the SubLink merger trees available: they contain the progenitor/descendant connectivity, and essentially all Subhalo properties.

Download SubLink Tree (88.3 GB across 14 files)

TNG50-2 has the LHaloTree merger trees available: they contain the progenitor/descendant connectivity, and the most important Subhalo properties.

Download LHaloTree (47.9 GB across 60 files)

Note: Extracting sub-trees for individual galaxies or halos

The merger trees are generally quite large. If you are interested in making a galaxy/halo selection based on a complex criterion related to assembly history, merger history, etc, then you will need to download the full tree files. If, however, you are only looking to study the merger history of a few galaxies/halos, you should instead consider extracting sub-trees on the fly using the Web API.
