Baryonic Tully–Fisher Test of Grumiller’s Modified Gravity Model
Abstract
Abstract We test Grumiller’s quantum motivated modified gravity model, which, at large distances, modifies the Newtonian potential and describes the galactic rotation curves of disk galaxies in terms of a Rindler acceleration term without need of any dark matter, against the baryonic Tully–Fisher feature that relates the total baryonic mass of a galaxy with flat rotation velocity of the galaxy. We estimate the Rindler acceleration parameter from the observed baryonic mass versus rotation velocity data of a sample of sixty galaxies. Grumiller’s model is found to describe the observed data reasonably well.
