<George R. Blumenthal> helped formulate the <cold dark matter> account of the formation of <galaxies> and larger cosmic structures. The 1984 paper with <Sandra Faber>, <Joel Primack> and <Martin Rees> considered matter whose early <velocity dispersion> was sufficiently small that free streaming would not erase fluctuations on galactic scales.
This connects a proposed microscopic property of <dark matter> to observable cosmic structure: surviving <density> fluctuations grow through <gravity>, and their initial spectrum constrains the later distribution of <galaxies>. The paper evaluated a model with calculable consequences, rather than merely adding unseen <mass> to individual systems.<Formation of galaxies and large-scale structure with cold dark matter by George R. Blumenthal and others>[Abstract: collisionless cold particles, undamped galactic-scale fluctuations and predictive fluctuation spectrum]{ref}
