This program calculates excitation energies E0 and E2 transition strengths within the "Confined Beta Soft" nuclear structure model as described in [N. Pietralla and O. M. Gorbachenko, Phys. Rev. C 70, 011304(R) (2004)]. Parameter fits are possible.

Cosmic ray electrons scatter on the photon fields around stars, including the sun, to create gamma rays by the inverse Compton effect. This program computes the spectrum and angular distribution of this emission. The software also includes general-purpose routines for inverse Compton scattering on a given electron spectrum, for example for interstellar or astrophysical source modelling. For further information see these publications: http://arxiv.org/abs/astro-ph/0607563,...

AGBStarViewer is an astronomical SW which was developed as a part of my Master Thesis at the University of Vienna. It is designed to compare star spectra and obtain best fits of many hundreds spectra. Licence: GPLv2

The core of Green Valley is an open source script-based software framework . It fits specially well in game engines but can be used in other programs as well. The extension of Green Valley provide some useful libraries for building a game.
