Enhanced Disruption of Axion Minihalos by Multiple Stellar Encounters in the Milky Way
Ian DSouza, Chris Gordon, John C. Forbes
If QCD axion dark matter formed post-inflation, axion miniclusters emerged from isocurvature fluctuations and later merged hierarchically into minihalos. These minihalos, potential…

The Disruption of Dark Matter Minihalos by Successive Stellar Encounters
Ian DSouza, Chris Gordon
Scenarios such as the QCD axion with the Peccei-Quinn symmetry broken after inflation predict an enhanced matter power spectrum on sub-parsec scales. These theories lead to the for…
