Interference of dark matter solitons and galactic offsets

摘要: Abstract By performing numerical simulations, we discuss the collisional dynamics of stable solitary waves in Schrodinger–Poisson equation. In framework a model which part or all dark matter is Bose–Einstein condensate ultralight axions, show that these can naturally account for relative displacement between and ordinary galactic cluster Abell 3827, whose recent observation first empirical evidence interactions beyond gravity. The essential assumption existence solitonic cores kiloparsec scale. For this reason, present simulations with benchmark value axion mass m = 2 × 1 0 − 24 eV, somewhat lower than one preferred cosmological structure formation if field ( ≈ 22 eV ). We argue future observations might bear out falsify coherent wave interpretation offsets.
