“…Such an analysis would of course require improved data on the gamma-ray spectrum at energies E γ ≲ m π 0 =2. However, several proposals for instruments which would provide significant improvements in energy resolution within that energy range have been advanced [72,73]. Thus, we see that "contamination" from the showering/hadron-decay contribution to the differential photon flux that arises in this DDM scenario when c g ∼ Oð1Þ may actually be an asset rather than a hurdle in the effort to distinguish this scenario from other models for the origin of this excess.…”

“…The equivalent for COMPTEL on board the CGRO satellite is 6 × 10 −5 cm −2 s −1 (Schoenfelder et al 1993). The Nuclear Compton Telescope (NCT) balloon experiment has a narrow-line sensitivity comparable to INTEGRAL (Bellm et al 2009), the DUAL gamma-ray mission is 30 times more sensitive (Boggs et al 2010), and the proposed Advanced Compton Telescope (ACT) satellite is 60 times better (Boggs 2006). These are labeled in Figure 6, where the cumulative number of catalog SNe Ia are shown as functions of the 847 keV flux (bottom, x-axis) and distance (top, x-axis).…”

“…The detection of gamma rays that escape the ejecta is the key to resolving the central mysteries of SNe Ia (Gehrels et al 1994;Höflich et al 1998;Boggs 2006). Since gamma rays are more penetrating and their opacities are much simpler than those for optical photons, they offer a more straightforward and direct probe of the inner mechanisms of SNe Ia Milne et al 2004;Isern et al 2008).…”

“…In our simulations we include the background from diffuse cosmic photons based on Gruber et al (1999) and the background from albedo photons produced in the Earth's atmosphere (Mizuno et al 2004;Ajello et al 2008). In Boggs (2006) these two components were found to be the dominating background for a Compton telescope at a low-inclination low Earth orbit. The generated background photons were processed through the same simulation and selection procedure described above, and then the reconstructed background events were added to the source events.…”
