NED Abstract

Copyright by Royal Astronomical Society. 1988MNRAS.233..115N On the influence of galaxy magnetic fieldS on the rotation curves in the outer discs of galaxies A. H. Nelson Deparment of Applied Mathematics and Astronomy, University College, Cardiff Accepted 1987 December 16. Received 1987 November 30; in original form 1987 June 1 Summary. The dynamical effect of magnetic stress on the tenuous outer gaseous discs of galaxies is discussed using a simplified cylindrical model. It is shown that the effects can be very significant, yielding rotation velocities well above the gravitational orbital velocity based on the visible matter. If this conclusion persists in fully three-dimensional galaxy models then the interpretation of flat rotation curves in the outer discs as being due to hidden matter may be erroneous.
