While we put a lot of efforts already into verifying the performance of different halo finders (Haloes going MAD, Subhaloes going Notts, Galaxies going MAD), this is certainly not the end of the story...

During the “Sussing Merger Trees” workshop we aim at validating the construction of merger trees. The basic idea is to get participants (with codes) to build their trees from the same set of pre-built halo catalogues and compare the results.
