Starscream is a code that I have developed for creating galaxy progenitors for N-body codes. The code implements a Springel-Hernquist model with a dark matter halo and a stellar disk, in a nutshell, and can write these initial conditions to a GADGET2 input file or others. More information is available in the manual.

The code is free to anyone who would like to use it, but comes with no warranty, neither expressed nor implied.

There are some videos of galaxy collisions created with Starscream and GADGET2 on Youtube.

Release Status: v1.1– 20110625, available here. Made a fix to support FFTW-3.2.2.

Repo Update: Replaced Autoconf with CMake!

License Info: Starscream is currently released under the GPL, but all new code will be released under the New/Modified BSD License.

NOTE! - I just started the Google Code project. It will take me awhile to fully migrate the project from my webpage.
