Preferred alignments of angular momentum vectors of galaxies in six
  dynamically unstable Abell clusters
  A spatial orientation of angular momentum vectors of galaxies in six
dynamically unstable Abell clusters (S1171, S0001, A1035, A1373, A1474 and
A4053) is studied. For this, two-dimensional observed parameters (e.g.,
positions, diameters, position angles) are converted into three-dimensional
rotation axes of the galaxy using `position angle - inclination' method. The
expected isotropic distribution curves for angular momentum vectors are
obtained by performing random simulations. The observed and expected
distributions are compared using several statistical tests. No preferred
alignments of angular momentum vectors of galaxies are noticed in all six
dynamically unstable clusters supporting hierarchy model of galaxy formation.
These clusters have a larger value of velocity dispersion. However, local
effects are noticed in the clusters that have substructures in the 1D-3D number
density maps.
