A New Dark Matter Candidate: Kaluza-Klein Solitons
Abstract
Background radiation has recently provided some strong constraints on conventional candidates for dark matter, which leads us to suggest another possibility: Kaluza-Klein solitons. These are the analogs of black holes in the simplest extension of general relativity from four to five dimensions, a theory which is otherwise in agreement with astrophysical data. We outline the essential properties of such solitons, which resemble balls of radiation-like matter. Information on solitons can be obtained from background radiation, the morphologies of galaxies, and gravitational lensing.
