Abstract

Despite years of research into dark matter, little has been done to explore models which are heavier than most WIMPs and lighter than most primordial black hole models, "blobs".  This parameter space is particularly difficult to probe, due to low number densities and low masses.  This talk will present a new model-independent mechanism that can be used to probe this difficult to reach region of dark matter parameter space.  Blobs form binaries which spin down and merge at high rates in the present and recent past.  The abundance of mergers can produce observable gravitational wave and electromagnetic signals.  I describe some of these unique signals and show how they already constrain parts of blob parameter space.
