HIDDEN MASSES AND CHARACTERISTIC SCALES IN THE COSMOGONY OF GALAXIES

Hidden masses, or dark matter, considered as a nonrelativistic and col lisionless medium are shown to be responsible for the existence of the Newtonian gravitational field, which at the early stages of large-sca le structure formation significantly exceeds the gravitational field, of baryonic matter. Therefore, some characteristic masses and lengths of galaxy cosmogony are shown to depend not only on universal physical constants but also on the density ratio of dark and baryonic matter, which exceeds unity. Examples of such characteristic scales and their role in the formation of galaxies and galaxy systems is discussed.
