Dark matter constraints from dwarf galaxies with data-driven J-factors
Alexandre Alvarez, Francesca Calore, Anna Genina +3
We present an updated analysis of the gamma-ray flux from the directions of classical dwarf spheroidal galaxies, deriving new constraints on WIMP dark matter (DM) annihilation usin…
Dark matter profiles and annihilation in dwarf spheroidal galaxies: prospectives for present and future gamma-ray observatories - I. The classical dSphs
A. Charbonnier, C. Combet, M. Daniel +8
Due to their large dynamical mass-to-light ratios, dwarf spheroidal galaxies (dSphs) are promising targets for the indirect detection of dark matter (DM) in gamma-rays. We examine…
Dark Matter Disc Enhanced Neutrino Fluxes from the Sun and Earth
Tobias Bruch, Annika H. G. Peter, Justin Read +2
As disc galaxies form in a hierarchical cosmology, massive merging satellites are preferentially dragged towards the disc plane. The material accreted from these satellites forms a…
