Formation of inflaton halos after inflation
Benedikt Eggemeier, Jens C. Niemeyer, Richard Easther
The early Universe may have passed through an extended period of matter-dominated expansion following inflation and prior to the onset of radiation domination. Sub-horizon density…
First Simulations of Axion Minicluster Halos
Benedikt Eggemeier, Javier Redondo, Klaus Dolag +2
We study the gravitational collapse of axion dark matter fluctuations in the post-inflationary scenario, so-called axion miniclusters, with N-body simulations. Largely confirming t…
Formation and mass growth of axion stars in axion miniclusters
Benedikt Eggemeier, Jens C. Niemeyer
We study the formation and the subsequent mass growth of axion stars inside axion miniclusters. Numerically solving the Schrödinger-Poisson equations with realistic initial conditi…
