Discrepancy in Velocity Dispersion and Rotation Curve of Galaxy

Authors: Mitali

The difference between observed and expected values of velocity discrepancy in mid 1930s gave rise to the problem of missing mass in galaxies. Further extra mass calculated from the gravitational lensing effect also supported strongly in favor of missing mass, called dark matter. However, this non-baryonic matter has not been detected directly. Meanwhile, effect of gravitational waves energy from galaxy and result of its angular momentum on rotational curve of spiral arms in outskirts of galaxy is not taken into consideration. Here, it is discussed how gravity waves energy can eliminate the necessity of dark matter and can explain the observational facts which are thought to be purely effect of dark matter.
