Theory of Dark Matter

Abstract

We discuss the hypothesis that the constituents of dark matter in the galactic halo are Primordial Intermediate-Mass Black Holes (PIMBHs). The status of axions and WIMPs is discussed, as are the methods for detecting PIMBHs with emphasis on microlensing. The role of the angular momentum J of the PIMBHs in their escaping previous detection is considered.
