Tip! Refine or expand your search. Authors are sometimes listed as 'Smith, J. K.' instead of 'Smith, John' so it is useful to search for last names only. Note this is currently a simple phrase search.

[ascl:1501.016] Colossus: COsmology, haLO, and large-Scale StrUcture toolS

Colossus is a collection of Python modules for cosmology and dark matter halos calculations. It performs cosmological calculations with an emphasis on structure formation applications, implements general and specific density profiles, and provides a large range of models for the concentration-mass relation, including a conversion to arbitrary mass definitions.

[submitted] SPARTA: Subhalo and PARticle Trajectory Analysis

SPARTA is an MPI-parallelized C-code framework for the dynamical analysis or particle-based simulations. The code follows the orbits of dynamical tracers such as particles and subhalos in dark matter halos. As a first application, SPARTA can record the first apocenters of all halo particles and compute the splashback radius of halos.
