Searching for dark matter isocurvature initial conditions with N-body Simulations
Searching dark matter isocurvature initial conditions N-body Simulations

Small fraction of isocurvature perturbations may exist and correlate with adiabatic perturbations in the primordial perturbations. Naively switching off isocurvature perturbations may lead to biased r...
Analytical Treatment of the Two-Body Problem with Slowly Varying Mass
Mass loss—binary systems—two-body problem—perturbations.
2010/9/15
The present work is concerned with the two-body problem with varying mass in case of isotropic mass loss from both components of the binary systems. The law of mass variation used gives rise to a pert...
