CLUMPY v3: $\gamma$-ray and $\nu$ signals from dark matter at all scales

TL;DR

CLUMPY v3 is an updated computational tool for calculating gamma-ray and neutrino signals from dark matter annihilation or decay across all cosmic scales, incorporating new features and improved usability.

Contribution

This release introduces the mean extragalactic signal, flexible definitions of halo properties, and enhanced user experience with better documentation and installation.

Findings

Includes extragalactic signals with cosmological parameters

Allows user-defined halo mass and concentration parameters

Simplifies installation and improves code usability

Abstract

We present the third release of the CLUMPY code for calculating $\gamma$-ray and $\nu$ 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 $\gamma$-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 $\Delta$. 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/.
