The distribution of dark matter at large scales and in gravitational lenses
… research study presented here concerns the flux ratio anomaly in the quadruply imaged strong gravitational lens, B1422+231, in which the contribution of $10-10^3M_{\odot}$ primordial black holes (PBHs) as a potential dark matter constituent is examined. I review the theory of gravitational …
