Abstract

Axionlike scalar fields and the Lane-Emden truncation of their periodic potential are analyzed as a model of dark matter halos. The apparent enhancement of infall velocities in merging clusters is intriguing: here it is tentatively explained via an intrinsic inelastic effect during relativistic soliton collisions. © 2014 American Physical Society.
