The CosmicProfiles project
****************************
This repository provides shape and density profile analysis tools for cosmological simulations (and beyond). Its features include
- overall halo shape determination, i.e. major, intermediate, minor axis vectors and shape quantities such as intermediate-to-major axis ratio or sphericity
- halo shape profile determination
- iterative shell-based shape profile determination algorithm for high-resolution halos
- iterative ellipsoid-based shape profile determination algorithm for lower-resolution halos
- user can choose between reduced shape tensor and non-reduced shape tensor
- supports
- 'direct' datasets (i.e. index catalogue provided by user) and
- FoF / SUBFIND halo catalogues
- Gadget-style I, II and HDF5 snapshot files
- all functionalities available for dark matter halos, gas particle halos and star particle halos
- in addition, allows for velocity dispersion tensor eigenaxes determination
- halo density profile estimation using direct binning and kernel-based approaches
- user can choose between direct binning into spherical shells and
- direct binning into ellipsoidal shells
- density profile fitting assuming either `NFW <https://ui.adsabs.harvard.edu/abs/1997ApJ...490..493N/abstract>`_, `Hernquist 1990 <https://ui.adsabs.harvard.edu/abs/1990ApJ...356..359H/abstract>`_, `Einasto <https://ui.adsabs.harvard.edu/abs/1965TrAlm...5...87E/abstract>`_ or `alpha-beta-gamma <https://arxiv.org/abs/1107.5582>`_ profile model
- concentration-mass relationship of halos easy to calculate
- mock halo generator: ellipsoidal or spherical, compatible with the 4 density profile models
- easy to interface with `pynbody` to work with halos identified in a cosmological simulation (see example scripts)
- easy to interface with `nbodykit` to harness large-scale structure capabilities (see example scripts)
- various profile plotting and 3D point cloud plotting tools
- efficient caching capabilities to accelerate look-ups
