Description

Infall of cold dark matter on a galaxy may result in caustic rings where the particle density is enhanced. They may be searched
for as features in the galactic rotation curves. Previous studies suggested the evidence for these caustic rings with universal, that is
common for different galaxies, parameters. Here we test this hypothesis with a large independent set of rotation curves by means
of an improved statistical method. No evidence for universal caustic rings is found in the new analysis.
