Bringing isolated dark matter out of isolation: Late-time reheating and indirect detection
Bringing isolated dark matter out of isolation: Late-time reheating and indirect detection
In standard cosmology, the growth of structure becomes significant following matter-radiation equality. In nonthermal histories, where an effectively matter-dominated phase occurs due to scalar oscillations prior to big bang nucleosynthesis, a new scale at smaller wavelengths appears in the matter power spectrum. Density perturbations that enter the horizon during the …
