Dark matter indirect detection in gamma-rays : dwarf spheroidal galaxies, galaxy clusters, and dark clumps

Séminaire IPAG de David Maurin (LPSC), jeudi 26 mai 2016 à 11h00, IRAM seminar room

The annihilation of dark matter particles into gamma-rays is one of the most promising channels for indirect detection. The ideal targets are regions of high dark matter density, close, and free of astrophysical background. In this context, after briefly reviewing the various interesting targets, I will focus more specifically on the dwarf spheroidal galaxies. I will discuss the determination of their dark matter profile and the related uncertainties, and how this affects their ranking as best targets. Finally, I will conclude with some perspectives regarding the evolution of the field.
