p3d is a general data-reduction tool for use with fiber-fed integral-field spectrographs (IFSs); although, the spectrum viewer works with spectrum data cubes of any origin. The tool is built about the proprietary software IDL (Harris/EXELIS; see http://www.harrisgeospatial.com), but can be used without any license. Most slowly running loops are implemented in parallelized C (OpenMP).

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 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 make GALPROP skymaps viewable in Aladin. This program performs this conversion, outputs both the original energy bins and energy-integrated spectra, and in addition convolves with a user-defined Gaussian both in energy bins and energy-integrated. ...

Finds the cosmological power spectrum from a N-body simulation using the MPI FFTW library. May be run as a parallel computation for increased resolution. Reads in binary Gadget2 files.

For the direct and detailed analysis of supernova spectra.

SSynth is a package of scientific software consisting of shell scripts and fortran source code for efficiently calculating a model stellar spectrum using the standard LTE, homogenous, and plane parallel approximations.

А GUI tool to visualize the development of the early Universe, the process of creation of galaxies and stars and the spectrum of the Cosmic Microwave Background Radiation (CMBR).

The aim of Stellar Population Spectrum Fitting (SPSF) is to collect different methods for fitting observed with a synthetic spectra.

We attempt to provide code to calculate the emergent spectrum of a Hydrogen atmosphere Neutron Star accurate to .01%.
