Clustering of cosmic string loops
  Observational effects of cosmic string loops depend on how loops are
distributed in space. Chernoff \cite{Chernoff} has argued that loops can be
gravitationally captured in galaxies and that for sufficiently small values of
$G\mu$ their distribution follows that of dark matter, independently of the
loop's length. We re-analyze this issue using the spherical model of galaxy
formation with full account taken of the gravitational rocket effect -- loop
accelerated motion due to asymmetric emission of gravitational waves. We find
that only loops greater than a certain size are captured and that the number of
captured loops is orders of magnitude smaller than estimated by Chernoff.
