CLUMPY v3: γ-ray and ν signals from dark matter at all scales

We present the third release of the CLUMPY code for calculating γ-ray and ν signals from annihilations or decays in dark matter structures. This version includes the mean extragalactic signal with several pre-defined options and keywords related to cosmological parameters, mass functions for the dark matter structures, and γ-ray absorption up to high redshift. For more flexibility and consistency, dark matter halo masses and concentrations are now defined with respect to a user-defined overdensity Δ. We have also made changes for the user’s benefit: distribution and versioning of the code via git, less dependencies and a simplified installation, better handling of options in run command lines, consistent naming of parameters, and a new Sphinx documentation at http://lpsc.in2p3.fr/clumpy/. Program Title:CLUMPY Program Files doi:http://dx.doi.org/10.17632/4n33mbh9bc.1 Licensing provisions: GPLv2 Programming language: C/C++ External routines/libraries:GSL (http://www.gnu.org/software/gsl), cfitsio ( http://heasarc.gsfc.nasa.gov/fitsio/fitsio.html), CERN ROOT (http://root.cern.ch; optional, for interactive figures and stochastic simulation of halo substructures), GreAT (http://lpsc.in2p3.fr/great; optional, for MCMC Jeans analyses) Nature of problem: Calculation of the γ-ray and ν signals from dark matter annihilation/decay at any redshift z. Solution method: New in this release: Numerical integration of moments (in redshift and mass) of the mass function, absorption, and intensity multiplier (related to the DM density along the line of sight). Restrictions: Secondary radiation from dark matter leptons, which depends on astrophysical ingredients (radiation fields in the Universe) is the last missing piece to provide a full description of the expected signal.
