Astrophysical explanations of suspected dark matter signals in dwarf galaxies
Alex Geringer-Sameth, Savvas M. Koushiappas, Matthew G. Walker +3
We present methods to assess whether gamma-ray excesses towards Milky Way dwarf galaxies can be attributed to astrophysical sources rather than to dark matter annihilation. As a ca…
Dark matter annihilation and decay profiles for the Reticulum II dwarf spheroidal galaxy
V. Bonnivard, C. Combet, D. Maurin +6
The dwarf spheroidal galaxies (dSph) of the Milky Way are among the most attractive targets for indirect searches of dark matter. In this work, we reconstruct the dark matter annih…
Spherical Jeans analysis for dark matter indirect detection in dwarf spheroidal galaxies - Impact of physical parameters and triaxiality
V. Bonnivard, C. Combet, D. Maurin +1
Dwarf spheroidal (dSph) galaxies are among the most promising targets for the indirect detection of dark matter (DM) from annihilation and/or decay products. Empirical estimates of…
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…
