The observability of gamma-rays from neutralino annihilations in Milky Way substructure
Savvas M. Koushiappas, Andrew R. Zentner, Terrence P. Walker
We estimate the probability of detecting gamma-rays from the annihilation of neutralino dark matter in dense, central regions of Milky Way substructure. We characterize Galactic su…
Gamma-rays From Neutralino Annihilation in Milky Way Substructure: What Can We Learn?
Savvas M. Koushiappas, Andrew R. Zentner, Terrence P. Walker
We estimate the probability of detecting gamma-rays from the annihilation of neutralino dark matter in the substructure of the Milky Way. We characterize substructure statistically…
Testing two nuclear physics approximations used in the standard leaky box model for the spallogenic production of LiBeB
J. P. Kneller, J. R. Phillips, T. P. Walker
The spallative production rates of Lithium, Beryllium and Boron (LiBeB) are a necessary component in any calculation of the evolution of these nuclei in the Galaxy. Previous calcul…
Global Constraints On Key Cosmological Parameters
G. Steigman, T. P. Walker, A. Zentner
Data from Type Ia supernovae, along with X-ray cluster estimates of the universal baryon fraction and Big Bang Nucleosynthesis (BBN) determinations of the baryon-to-photon ratio, a…
Observational Constraints On Power-Law Cosmologies
M. Kaplinghat, G. Steigman, I. Tkachev +1
In a class of models designed to solve the cosmological constant problem by coupling scalar or tensor classical fields to the space-time curvature, the universal scale factor grows…
Rotational Mixing And The Primordial Lithium Abundance
M. H. Pinsonneault, V. K. Narayanan, G. Steigman +1
There has been recent progress in the study of the angular momentum evolution of low mass stars (Krishnamurthi et al 1997a). Theoretical models can now be constructed which reprodu…
