Enhanced Disruption of Axion Minihalos by Multiple Stellar Encounters in the Milky Way
Speakers: Chris Gordon (University of Canterbury) If QCD axion dark matter formed post-inflation, axion miniclusters emerged from isocurvature fluctuations and later merged hierarchically into minihalos. These minihalos, potentially disrupted by stellar encounters in the Milky Way, affect axion detectability. We extend prior analyses by more accurately incorporating multiple stellar encounters and dynamical relaxation timescales, simulating ... Read more
