Velocity relationships of isolated galaxy pairs in support of MOND-type theories
Subject
Abstract
The MOND-type theories of AQUADratic Lagrangian (AQUAL) and GRavitational Anti-Screening (GRAS) are applied to isolated galaxy pairs. Theoretical relationships between their intervelocities, line-of-sight velocities, and their baryonic masses will be derived. These relationships will be compared with observations taken of a set of 3970 highly isolated pairs. The theoretical velocity relationships and distributions provided by AQUAL and GRAS are found to be in very good agreement with these observations. This agreement indirectly implies that there is no fall-off in the rotational curves of galaxies, which remain flat out to large distances.
