TNG-Cluster has the virtual 'simulation.hdf5' container file available.
TNG-Cluster has the SubLink merger trees available: they contain the progenitor/descendant connectivity, and essentially all Subhalo properties.
TNG-Cluster has the LHaloTree merger trees available: they contain the progenitor/descendant connectivity, and the most important Subhalo properties.
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.
TNG-Cluster has the Stellar Assembly catalog available.
TNG-Cluster has the Merger History catalog available.
TNG-Cluster has the "TNG-Cluster Catalog" available.
TNG-Cluster has the Cluster Relaxedness catalog available.
TNG-Cluster has the Cluster Cool-core Criteria catalog available.
TNG-Cluster has the Cluster Projections catalog available.
