14. dSphs, J-factors and DM limits

Mr Mauro Valli (SISSA, INFN)

19/09/2014, 10:00

Dwarf spheroidal galaxies (dSph) are dominated dark matter (DM) astrophysical objects which allow us to put tight constraints on the velocity averaged annihilation cross-section of weakly interacting massive particles (WIMPs). Such bounds, coming from the observation of dSphs in the gamma-ray band, depend crucially on the mass modelling of this peculiar class of galaxies. We will review the...

15. Anti-nuclei from Dark Matter

Mr Andrea Vittino (Universita' di Torino and INFN Torino)

Light anti-nuclei, namely anti-deuteron and anti-helium, can be produced through the nuclear coalescence of the anti-protons and the anti-neutrons that are originated in a dark matter pair annihilation event. At low kinetic energies, the fluxes of these bound states are found to dominate over the astrophysical background and thus anti-nuclei may be considered as a very promising channel for a...

16. On the dependence of cosmic ray propagation parameters upon some basic source properties.

Mr Yoann GÉNOLINI (LAPTh)

19/09/2014, 10:40

An understanding of the origin of cosmic rays requires inferring source as well as propagation parameters from the analysis of the data. While it is well appreciated that propagation parameters depend on the propagation model adopted, it is also important to gauge to what extent they are affected by more or less implicit assumptions on the source properties. I present some results about such...
