Lower Limits on the Strengths of Gamma Ray Lines from WIMP Dark Matter Annihilation

Kevork N. Abazajian^{1, 2}Prateek Agrawal,¹Zackaria Chacko,¹ and Can Kilic³

The line sensitivity for Fermi-LAT may improve substantially with systematic improvement at better than the Poisson count rate. For example, this may occur with enhanced energy resolution for lines over the lifetime of Fermi-LAT. Moreover, for certain cases of dark matter spins, any future gamma-ray experiment with even higher energy resolution (e.g. GAMMA-400 [44]) may prove to have line sensitivities or constraints on dark matter annihilation be more significant than that for the continuum.

GRIPS and its strong connections to the GeV and TeV bands

O. Tibolla¹, K. Mannheim¹, A. Paravac¹, J. Greiner² and G. Kanbach²

Conclusions. - GRIPS is proposed to be launched in 2020 and its advent will answer many of the open questions in high energy astrophysics; we showed that the answers to such questions are hidden in the MeV gamma-ray band and that deep multiwavelength studies (in particular together with higher energy instruments, such as Fermi, Gamma-400 and CTA) will be able to provide the seeked answers. The deep importance of closing the MeV-gap can be underlined by W. Atwood, one of the fathers of Fermi: "If 10 years ago I could do an experiment from hundreds of keV to hundreds of MeV, I would have done it instead of GLAST". We have shown how crucial GRIPS will be inanswering the one-century old question of the origin of cosmic rays.
