FLAT ROTATION CURVES - A RESULT OF THE HELICAL INVERSE CASCADE IN TURBULENT MEDIA

We have modeled the rotation curves of 21 galaxies observed by Amram e t al. (1992), by combining the effects of rigid rotation, gravity, and turbulence. The main motivation behind such modeling is to study the formation of coherent structures in turbulent media and explore its ro le in the large-scale structures of the universe. The values of the pa rameters such as mass, turbulent velocity, and angular velocity derive d from the rotation curve fits are in good agreement with those derive d from the prevalent models.
