Python routines for computing Navarro-Frenk-White halo properties
Project description
# Navarro-Frenk-White (NFW) Halo Class
[![Build Status](https://travis-ci.org/joergdietrich/NFW.svg?branch=master)](https://travis-ci.org/joergdietrich/NFW) [![Coverage Status](https://coveralls.io/repos/github/joergdietrich/NFW/badge.svg?branch=master)](https://coveralls.io/github/joergdietrich/NFW?branch=master) [![DOI](https://zenodo.org/badge/doi/10.5281/zenodo.50664.svg)](http://dx.doi.org/10.5281/zenodo.50664)
This class implements the NFW (Navarro, Julio F. Frenk, Carlos S. White, Simon D. M., “A Universal Density Profile from Hierarchical Clustering”, The Astrophysical Journal vol. 490, pp. 493-508, 1997) halo profile. It allows easy computation of halo quantities such as mass at and radius of specified overdensities. Overdensities can be specified either with respect to the critical or mean density of the Universe.
Class instances can be instantiated at different overdensities. As such the class allows for easy conversion between masses and concentration parameters between different mass definitions.
## Dependencies
This implementation of the NFW halo properties depends on
numpy >= 1.9
scipy >= 0.16
astropy >= 1.0
Older versions may work but are untested.
