Galactic Rotation Curves with No Dark Matter

ORAL

Abstract

Recent literature has shown the apparent existence of spiral galaxies without dark matter. Usually the cold dark matter prescription is the explanation to the missing matter in the rotation curves for spiral galaxies. This recent literature seems to challenge this paradigm. In this talk, we present various fits to the respective galaxies that show that although dark matter may not be needed to produce a "fit", many of the resulting fits are not consistent with other observational data such as Tully Fisher and the radial acceleration rule. We further explore to see if alternative gravity can provide fits in these cases whereas alternative gravity (such as MOND and conformal gravity) are usually used as an alternative to dark matter.
