Alternative gravity rotation curves for the Little Things Survey
  Galactic rotation curves have proven to be the testing ground for dark matter
bounds in spiral galaxies of all morphologies. Dwarf galaxies serve as an
increasingly interesting case of rotation curve dynamics due to their typically
rising rotation curve as opposed to the flattening curve of large spirals.
These galaxies usually vary in galactic structure and mostly terminate at small
radial distances. This, coupled with the fact that Cold Dark Matter theories
struggle with the universality of galactic rotation curves, allow for exclusive
features of alternative gravitational models to be analyzed. Recently, the
THINGS (The HI Nearby Galactic Survey) has been extended to include a sample of
25 dwarf galaxies now known as the LITTLE THINGS Survey. Here, we present a
thorough application of alternative gravitational models to the LITTLE THINGS
survey, specifically focusing on conformal gravity and Modified Newtonian
Dynamics. An analysis and discussion of the results of the fitting procedure of
the two alternative gravitational models are explored, as well as the resulting
rotation curve predictions of each. Further, we show how these two alternative
gravitational models account for the recently observed universal trends in
centripetal accelerations in spiral galaxies. We posit here that both conformal
gravity and MOND can provide an accurate description of the galactic dynamics
without the need for dark matter.
