Local overdensity finder
WitrynaA number of local mass overdensity variables, both including and excluding the halo mass itself, are tested as measures of a halo's environment. The simple functional dependence on z, M0, and xi of the merger rate found in our earlier work is largely preserved in different environments, but we find that the overall amplitude of the … WitrynaRanBox. Source code of anomaly detection finder in the copula space. This repository contains source code for the programs RanBox and RanBoxIter. The algorithms are two versions of an anomaly finding routine which transforms multidimensional data into a copula space, and scans it to localize a small multi-dimensional interval which …

WitrynaThe resulting filaments are regions connecting haloes with halo mass overdensity at least five times the background halo mass density, and which are less than 10 Mpc h −1 long. The full catalogue at z = 0.1 has ∼30 000 filaments and ∼44 000 end points, with 45 per cent of the halo mass fraction in filaments and 36 per cent of the haloes (in … Witryna3 lut 2024 · Values of the Hubble constant between the direct measurements from various independent local observations and that inferred from the cosmic microwave background with the $Λ$-cold-dark-matter model are in tension with persistent significance.

WitrynaWe present and test a new halo finder based on the spherical overdensity (SO) method. This new adaptive spherical overdensity halo finder (ASOHF) is able to identify dark matter haloes and their substructures (subhaloes) down to the scales allowed by the analysed simulations. The code has been especially designed for the adaptive mesh …
