Can Alternative Gravity Explain Galaxies which Appear to have No Dark Matter
ORAL
Abstract
Alternative gravity has long been shown to provide analysis and descriptions of rotation curve physics without the need for dark matter. Recently, numerous authors have made claims of galaxies whose rotation curves can be fit without dark matter. Although interesting enough, these galaxies can serve to provide new tests of the validity of alternative and standard gravity. To this end, we focus on two major theories, namely conformal weyl gravity and modified newtonian dynamics, both of which have had tremendous success in fitting galactic rotation curves without using any dark matter. The Tully Fisher relation and the Radial Acceleration rule will be explored in these galaxies to serve as tests for the parameters that generate no dark matter in standard gravity and allow us to see if alternative gravity that requires no dark matter by fiat can provide reasonable predictions for the data.
