Randomized trial shows core-halo relation in quantum wave dark matter, indicating implications for galaxy formation.

This research aims to investigate the core-halo relationship in quantum wave dark matter using 3D simulations.
Simulated the structure of gravitationally collapsed objects using the Schrödinger-Poisson equation for dark matter particles.
Examined the internal structure of virialized halos and merged solitons to create individual virialized objects.
Achieved high simulation resolution with adaptive mesh refinement and GPU acceleration.
Identified a solitonic core at the center of halos with a distinct profile from those in warm or self-interacting dark matter models.
Verified a scaling relation Mc∝a(-1/2)Mh(1/3) for core and halo masses, predicting dwarf galaxies to have kiloparsec-sized cores.
Forecasted massive solitonic cores within galaxies at high redshift, providing conditions for forming early stellar structures.

Schive et al. (2014) studied this question.
