Your Python library to calculate diffuse signals from dwarf spheroidal galaxies!
The Python library diffSph offers a fast and interactive way to calculate diffuse emission signals from dwarf spheroidal galaxies. Annihilation/decay of dark matter particles as well as generic astrophysical sources of cosmic-ray electrons and positrons can be investigated using this tool.
Use Git or checkout with SVN using the web URL, e. g.:
git clone https://github.com/mertio1/diffsph.gitor
svn co https://github.com/mertio1/diffsph.gitFor global installations, while in the diffSph’s main folder type:
python setup.py bdist_wheeland (after a few minutes)
pip install .diffSph can be used for a variety of calculations. Particularly interesting are
- Emission profiles for indirect Dark Matter detection with gamma rays (J-, D- factors)
- Synchtrotron-radiation emission profiles
- Upper bounds on Dark Matter annihilation cross sections
The cornerstones of diffSph are the spectra, profiles and utils modules and the top-level functions can be found in pyflux and limits as depicted in the figure below
