Disruption of Dark Matter Minihaloes in the Milky Way environment: Implications for Axion Miniclusters and Early Matter Domination

Understand

Many theories of dark matter beyond the Weakly Interacting Massive Particles (WIMP) paradigm feature an enhanced matter power spectrum on sub-parsec scales, leading to the formation of dense dark matter minihaloes.

• Future local observations are promising to search for and constrain such substructures.
• The survival probability of these dense minihaloes in the Milky Way environment is crucial for interpreting local observations.
• In this work, we investigate two environmental effects: stellar disruption and (smooth) tidal disruption.
