Comment on “Evidence for supersymmetric dark matter annihilations into [Formula presented] rays”
Physical Review D - Particles, Fields, Gravitation and Cosmology 57:4 (1998) 2637-2638
Abstract:
The evidence for supersymmetric dark matter annihilations presented by Strausz is based on both an analysis of data from the JACEE balloon-borne emulsion experiment which ignores systematic uncertainties and on a flawed analysis of background data from the Whipple gamma-ray observatory. When the latter analysis is corrected, it is found that there is no evidence for a peak in the 3.5–4.0 TeV regime in the Whipple data. Furthermore, were any such excess seen in the Whipple data, it would indicate a flux in gross conflict with the JACEE upper limits. It is therefore concluded that no evidence exists for an annihilation line due to supersymmetric dark matter. © 1998 The American Physical Society.New limits to the infrared background: Bounds on radiative neutrino decay and on contributions of very massive objects to the dark matter problem

Abstract:
From considering the effect of γ-γ interactions on recently observed TeV gamma-ray spectra, improved limits are set to the density of extragalactic infrared photons which are robust and essentially model independent. The resulting limits are more than an order of magnitude more restrictive than direct observations in the 0.025‒0.3 eV regime. These limits are used to improve constraints on radiative neutrino decay in the mass range above 0.05 eV and to rule out very massive objects as providing the dark matter needed to explain galaxy rotation curves. Lower bounds on the maximum distance which TeV gamma rays may probe are also derived. © 1998 The American Physical Society.The spectrum of tev gamma rays from the crab nebula
