Description
A cosmological scenario where axions provide the dark matter in the universe is considered. Fluctuations in the axion-field energy density produced by domain walls and strings cause the appearance of ''axion clumps'' of masses of order 106M/sub cirdot/ which most likely collapse to black holes by or at the time that the universe becomes axion dominated at Tapprox.10 eV. These objects form the building blocks for the clustering hierarchy theory of galaxy and supercluster formation on scales up to approx.10 Mpc and 1015M/sub cirdot/. .AE
