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, http://arxiv.org/abs/0801.2178, http://arxiv.org/abs/1104.2093, http://adsabs.harvard.edu/abs/2013NuPhS.239..266O and this conference presentation: https://confluence.slac.stanford.edu/download/attachments/130879399/poster_symposium_sun_2012.pdf and the corresponding conference paper http://arxiv.org/abs/1307.6798 2017 June 16: now available from gitlab https://gitlab.mpcdf.mpg.de/aws/stellarics which will be used for future develpments.

This library contains the parametrization of pp->gamma cross section functions based on Phys.Rev. D90 (2014) 12, 123014 (astro-ph/1406.7369) work. The functions are written in Python, Fortran and Matlab. Please, if you use this library DO NOT reference to this webpage, instead reference to Phys.Rev. D90 (2014) 12, 123014 (astro-ph/1406.7369), "Parametrization of gamma-ray production cross-sections for pp interactions in a broad proton energy range from the kinematic threshold to PeV energies" by Ervin Kafexhiu, Felix Aharonian, Andrew M. ...

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. ...

A C++ version of the public GALPROP (http://galprop.stanford.edu) routine to compute non-thermal bremsstrahlung, with added features to compute the gamma-ray emissivity either differential or in user-defined bands.

Oree - Optimum Real-time Estimation of Events of Interaction: real-time reconstruction of photon interaction events in Gamma Cameras. Optionally making use of a CUDA enable GPU, Oree achieves reconstruction of over 1M events/sec.
