stellarics
Inverse Compton emission from heliospheres of sun and stars
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. -

galplot
Plot GALPROP output
Plot package for GALPROP https://sourceforge.net/projects/galprop Plots models and data for cosmic-ray spectra, secondary/primary ratios, gamma rays, synchrotron. Includes gamma-ray source population synthesis and corresponding plots. For gamma rays, convolves models with the Fermi-LAT response. This release is to assess interest. It requires many input data files (not included) which will be made available as required. With the data provided cosmic-ray spectra and ratios and source population synthesis will work. ... -

gcr_convert
converts cosmic-ray files from GALPROP for viewing / plotting.
The GALPROP program (http://galprop.stanford.edu) computes cosmic-ray propagation in the Galaxy, in 2D or 3D. The ouput cosmic-ray distribution is in the form of FITS files which however are not convenient for viewing or plotting with the standard ftools program fv, since the files have 4 or 5 dimensional arrays (due to the momentum and species axes) while fv handles only 3 dimensional arrays. This program converts to fv-compatible FITS files, either from 2D to (R,z) or from 3D to (x,z) at y=0 or (x,y) at z=0, in each case for a chosen cosmic-ray species. ... -

galprop_skymap_convert
Convert galprop skymaps to standard healpix
A routine for converting GALPROP-generated HealPix skymaps to a compatible format which can be plotted by Aladin (v7), available from CDS at http://aladin.u-strasbg.fr. This allows free rotation of the sphere, avoiding the distortions of Aitoff and other projections often used. It is a very practical way to view and prepare skymap plots of GALPROP output. GALPROP outputs a spectrum per HealPix pixel, while Aladin requires each energy to be stored as a column. A conversion is required to... -

galprop_propel
GALPROP update for accurate propagation calculation
The GALPROP program (http://galprop.stanford.edu) computes cosmic-ray propagation numerically. To obtain manifestly accurate solutions an explicit method is now available to replace the Crank-Nicolson operator-splitting method. This can be implemented in the public version of GALPROP with the update provided here. Instructions: replace the four files propel.cc, propel_diagnostics, Galdef.cc and Galdef.h and rebuild the executable. -

hadronic gamma rays
gamma rays from hadronic processes in astrophysics
Cosmic-ray hadronic interaction matrices for gamma-ray and other secondaries for an interstellar medium target are available as described in Huang et al. Astroparticle Physics, 27, 429 (2007). These require significant effort in practice to compute emissivities for given input spectra. To supplement these matrices I provide here a C++ class which reads the matrices, interpolates on user-defined particle and gamma-ray energy grids, and computes the gamma-ray emissivity either differential or in user-defined bands. ... -

bremsstrahlung
Non-thermal bremsstrahlung c++ routine
