CLUMPY: Jeans analysis, $\gamma$-ray and neutrino fluxes from dark matter (sub-)structures

Understand

We present an update of the CLUMPY code for the calculation of the astrophysical J-factors (from dark matter annihilation/decay) for any Galactic or extragalactic dark matter halo including substructures: halo-to-halo concentration scatter may now be enabled, boost factors can include several levels of substructures, and triaxiality is a new option for dark matter haloes.

• This new version takes advantage of the CFITSIO and HEALPix libraries to propose FITS output maps using the HEALPix pixelisation scheme.
• Skymaps for $\gamma$-ray and $\nu$ signals from generic annihilation/decay spectra are now direct outputs of CLUMPY.
• Making use of HEALPix routines, smoothing by a user-defined instrumental Gaussian beam and computing the angular power spectrum of the maps is now possible.
