Abstract—The
probability of strong gravitational lensing of distant compact
objects by transparent lenses with King mass distributions is
calculated. Examples of such lenses are globular clusters, dwarf
galaxies, and clusters of hidden mass. The lens masses thus range
from 103 to 109 M
, intermediate between
stellar and galactic masses. Taking account of the conic caustic
of King lenses and the fractal large-scale distribution of matter
along the line of sight, it is possible to explain the
correlation between quasars and nearby galaxies as the effect of
strong gravitational lensing of the active nuclei of distant
galaxies by globular clusters in the halos of nearby galaxies.
Observational tests for verifing this mesolensing hypothesis are
described.
