Abstract

The LIGO observatory has recently reported several detections of gravitational waves from the coalescence of binary black holes We consider the extraordinary possibility that the detected events involving heavier masses are mergers of primordial black holes making up the dark matter in the Universe We will describe various ways of testing this proposition once more gravitational wave data is gathered survey some of the existing constraints and present a novel probe of massive compact dark matter in the relevant mass range based on strong gravitational lensing of fast radio bursts We will conclude with a summary of observational prospects to test the proposed scenario over the next decade
