The question of the nature of the dark matter in the Universe remains one of the most outstanding unsolved problems in basic science. One of the best motivated particle physics candidates is the lightest supersymmetric particle, assumed to be the lightest neutralino—a linear combination of the supersymmetric partners of the photon, the Z boson and neutral scalar Higgs particles. Here we describe DarkSUSY, a publicly available advanced numerical package for neutralino dark matter calculations. In DarkSUSY one can compute the neutralino density in the Universe today using precision methods which include resonances, pair production thresholds and coannihilations. Masses and mixings of supersymmetric particles can be computed within DarkSUSY or with the help of external programs such as FeynHiggs, ISASUGRA and SUSPECT. Accelerator bounds can be checked to identify viable dark matter candidates. DarkSUSY also computes a large variety of astrophysical signals from neutralino dark matter, such as direct detection in low-background counting experiments and indirect detection through antiprotons, antideuterons, gamma-rays and positrons from the galactic halo or high-energy neutrinos from the centre of the Earth or of the Sun. Here we describe the physics behind the package. A detailed manual will be provided with the computer package.

Very high-energy gamma rays from the direction of Sagittarius A* (2004, methodology): “The continuum spectra generated by the DarkSusy program (Gondolo et al. 2004) are well approximated by F ∼ E−αe−(E/Mcut ) with α = 2.2...2.4 and Mcut = 0.15...0.3Mχ depending on the annihilation channel 1.”

SEARCHING FOR DARK MATTER ANNIHILATION IN RECENTLY DISCOVERED MILKY WAY SATELLITES WITH FERMI-LAT (2016, background): “The “J-factor” is the square of the DM density (ρ) as a function of position l integrated along the light-of-sight (l.o.s.) in the region of interest (ROI), and ∆Ω denotes the solid angle over which the J-factor is calculated (Gondolo et al. 2004).”
Constrained supersymmetry after two years of LHC data: a global view with Fittino (2012, methodology): “A cross-check of the relic density computation between micrOMEGAs versions 2.2 and 2.4 [85] and DarkSUSY [86] version 5.0.5 (via the AstroFit interface) is performed, which yields compatible results in terms of allowed parameter space.”
