Bolt

Dev

Build Status codecov

Bolt is a pure-Julia integrator for the Boltzmann equations in cosmology. It can accurately compute the gradient of the CMB power spectrum, with respect to cosmological parameters, using forward-mode automatic differentiation.

Contributors: Jamie Sullivan, Zack Li, Marius Millea

Install

Bolt requires Julia 1.5+. To install, from the package prompt, run:

pkg> add https://github.com/xzackli/Bolt.jl
