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.git

or

svn co https://github.com/mertio1/diffsph.git

For global installations, while in the diffSph’s main folder type:

python setup.py bdist_wheel

and (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
