2. 1. Indirect Detection of Neutralino Dark Matter

   Author : Piero Ullio; Marc Kamionkowski; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Theoretical Physics; teoretisk fysik;

   Abstract : The detection of dark matter is a primary issue in today's astrophysics. Although the lightest supersymmetric particle, generally assumed to be a neutralino, is an excellent dark matter candidate, it is not easy to prove that such particles are the main component of galactic halos.

4. 2. Dark matter signal normalisation for dwarf spheroidal galaxies : A frequentist analysis of stellar kinematics for indirect Dark Matter searches

   Author : Andrea Chiappo; Jan Conrad; Piero Ullio; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; dark matter; dwarf galaxies; kinematics and dynamics of galaxies; fysik; Physics;

   Abstract : Indirect detection strategies of Dark Matter (DM) entail searching for signals of DM annihilation or decay, typically in the form of excess positrons or high-energy photons above the astrophysical background, originating from (inferred) DM-rich environments. Due to their characteristics, dwarf spheroidal satellite galaxies (dSphs) of the Milky Way are considered very promising targets for indirect particle DM identification. READ MORE
