Nanolensed fast Radio Bursts
arXiv:1711.04764 · doi:10.3847/1538-4357/aa8b70
Abstract
It is suggested that fast radio bursts can probe gravitational lensing by clumpy dark matter objects that range in mass from $10^{-3}M_{\odot}$ to $10^2 M_{\odot}$. They may provide a more sensitive probe than observations of lensing of objects in the Magellanic Clouds, and could find or rule out clumpy dark matter with an extended mass spectrum.
