Web8 Jul 2024 · You shouldn't use SubhaloParent, this is a hierarchical index, so it is meant to identify a subhalo of a subhalo (this is a rare occurrence in these types of simulations). Better to just use SubhaloGrNr, which tells you the … WebWe find that the overall subhalo abundance is relatively insensitive to properties of the disc aside from its total mass. For a disc that contains 5% of M_{vir}, the mean subhalo …
Subhaloes going Notts: The subhalo-finder comparison project
Webthe shape of the observed Milky Way satellite distribution to those of high-resolution subhalo samples from simulations, we find agreement for samples of bright satellites, but significant deviations if faint satellites are included in the analysis. These deviations might result from observational incompleteness. Web10 May 2024 · (1) If the tree algorithm couldn't find a descendant (or progenitor), then this subhalo has no connections through time, so won't "exist" in the tree. This could happen for various complex reasons, I would typically expect for very low mass subhalos, or difficult merger scenarios. sterling connect direct interview questions
HBT: the Merger-Tree Based Subhalo-Finder - Durham University
Web16 Mar 2012 · We present a detailed comparison of the substructure properties of a single Milky Way sized dark matter halo from the Aquarius suite at five different resolutions, as identified by a variety of different (sub-)halo finders … WebThe halo and subhalo finder produces a separate output file, summarizing the properties determined by the on the fly analysis. These run immediately before every simulation output, and also sort the particles in the particle data output according to group membership, subhalo membership and binding energy. WebWe present a new algorithm for identifying the substructure within simulated dark matter haloes. The method is an extension of that proposed by Tormen et al.
