Core-collapse, evaporation, and tidal effects: the life story of a self-interacting dark matter subhalo

HIGHLIGHTS

  • who: Zeng Zhichao Carton and colleagues from the of Physics, The Ohio State University, WWoodruff Columbus, OH, USA have published the paper: Core-collapse, evaporation, and tidal effects: the life story of a self-interacting dark matter subhalo, in the Journal: (JOURNAL)
  • what: The authors develop a new hybrid semi-analytical + N-body method to study the evolution of SIDM subhaloes with high fidelity from core formation to core-collapse in staged simulations. For each subhalo N-body particle, the authors evaluate the evaporation probability based on knowledge of the particle`s position and velocity . . .
