Newtonian collapse of scalar field dark matter
Newtonian collapse of scalar field dark matter
In this paper, we develop a Newtonian approach to the collapse of galaxy fluctuations of scalar field dark matter under initial conditions inferred from simple assumptions. The full relativistic system, the so-called Einstein-Klein-Gordon system, is reduced to the Schr\"odinger-Newton one in the weak-field limit. The scaling symmetries of the SN …
