The code associated with our recent paper on enhancing the resolution of cosmological N-body simulations is now available in the Galacticus repo. This blog post explains how it works and how to use it.

The v0.9.4 installation script now supports a "binary" option which installs a statically-linked binary copy of Galacticus and avoids the need to install the various libraries and tools required to compile Galacticus. It's the fastest way to get Galacticus up and running.

I've created a new repo at BitBucket that will hold tools useful for working with Galacticus. The first one added is a tool written by Christoph Behrens to convert RockStar/ConsistentTrees format merger trees into a simple CSV format that can then be parsed by Galacticus' own conversion tools. (If only everyone would adopt a sensible merger tree format right........?)

It took longer than usual, but v0.9.3 of Galacticus is now released! The linked article describes the significant new features and improvements.

As promised, the final major addition to v0.9.3 prior to its release: detailed tracking of subhalo orbits. v0.9.3 itself should be finalized and released early in January.

Thanks to a contribution from Stephanie Dörschner, Galacticus can now convert trees from the Bolshoi simulation database into Galacticus format - see the latest patch to v0.9.3.

Penultimate major new feature before the v0.9.3 release: fully self-consistent modelling of reionization and the evolution of the intergalactic medium.

Just pushed out a new feature which computes emission line luminosities for galaxies in Galacticus.

Making it easier to move models between versions of Galacticus.
