Classification of gamma-ray targets for velocity-dependent and subhalo-boosted dark-matter annihilation
Thomas Lacroix, Gaétan Facchinetti, Judit Pérez Romero, Martin Stref, Julien Lavalle, David Maurin, M. Sánchez-Conde
Izvirni znanstveni članek
Oznake: dark matter theory;dwarf galaxies;galaxy clusters;gamma-ray theory;
Gamma-ray observations have long been used to constrain the properties of dark matter (DM), with a strong focus on weakly interacting massive particles annihilating through velocity-independent processes. However, in the absence of clear-cut observational evidence for the simplest candidates, the in ...

Indirect searches with gamma rays set strong constraints on the properties of self-annihilating dark matter particle candidates. Observations of dwarf galaxies and galaxy clusters are especially interesting. Here we revisit the calculation of the annihilation flux by considering a velocity-dependent ...

Analytical insight into dark matter subhalo boost factors for Sommerfeld-enhanced s- and p-wave [gamma]-ray signals

Abstract As searches for thermal and self-annihilating dark matter (DM) intensify, it becomes crucial to include as many relevant physical processes and ingredients as possible to refine signal predictions, in particular those which directly relate to the intimate propertie ...
